Install OS X El Capitan on Mac [Direct Download]

Although there is no official way to download OS X El Capitan from outside the Mac App Store [MAS], we have found a reliable workaround for those who are facing similar issues with the OS X upgrade.

Installing El Capitan

When you download OS X El Capitan using the Mac App Store, a raw package (.pkg) file is downloaded from the Apple server. This raw file is not installable on its own. While downloading the package, MAS processes and converts it into an executable (.app) file, which can then be installed on your Mac.

In this workaround, we’ll be downloading the raw package directly from the Apple server using a suitable download manager. This will accelerate the download speed, and reduce the risk of download error at the same time. We’ll then configure the system in such a way that the MAS downloads and installs the new version of OS X from the locally downloaded raw package, instead of the one available on the Apple server.

The end result is the same as you would get if you had downloaded OS X El Capitan directly from MAS. The only thing you have skipped here is the annoying download interruptions and slow download speeds.

Note: On Mac App Store, the estimated download time was around 15 hours on a 2 Mbps connection. Using a download manager like Folx, the setup package was downloaded within 5 hours on the same connection.

OS X El Capitan [Direct Download]

First, download the El Capitan package (.pkg) file from the Apple server using a suitable download manager.

El Capitan package URL:

#Update: Here, we have mentioned the URL of the package file for OS X 10.11. If the latest version of OS X El Capitan available on the Mac App Store is a different one, MAS will fetch it from a different location. Hence the workaround mentioned here will no longer work, unless you know the URL of the latest package file and create the directory structure on localhost based on the same.

Before downloading the package, ensure that it is the latest version of El Capitan released on the MAS. To find out the URL of the latest El Capitan package file, you can either check out the comments below or search on the Internet for it.

Once you have got the raw package (ftk3252456602304584541.pkg), you need to configure your Mac so that the MAS uses it as the source for downloading OS X El Capitan. For this, first you need to edit the hosts file and point the root domain of the download URL ( to localhost ( To modify the hosts file as required, follow the steps below:

#1 Open Terminal from the Launchpad or Applications list.

#2 Type “sudo nano /etc/hosts” and hit the return key. You’ll be asked for your password. Enter your admin password. The hosts file is now open in editable mode within the Terminal window.

#3 Add the following line to the end of the file: “”.

Editing hosts file on Mac

#4 Press control + X (^X), then Y and hit return to save the file and return to Terminal prompt.

The root domain has now been pointed to localhost IP of your computer.

Note: Sometimes, you might need to flush the DNS cache for the changes to take effect. To flush DNS cache, type “sudo killall -HUP mDNSResponder” in the command line and hit return.

Next, you need to replicate the path of the source package on your computer in the same way as it is represented in the original URL. Only then, will MAS be able to download the package from localhost server.

To replicate the original download URL on localhost, you need to create the same directory structure on your computer within a particular folder, and then assign that folder as the root of the localhost server.

Note: OS X comes preinstalled with Python, which natively includes a SimpleHTTPServer by default. This server can turn any directory on your Mac into a web server directory (on localhost).

In this example, we will create a folder named “osxapps_local” on Desktop, and replicate the directory structure of the package URL under it. Follow the steps below to create the directory structure and then host “osxapps_local” as the root directory on localhost.

#1 Open Terminal from the Launchpad or Applications list.

#2 Type “cd Desktop” on the command line and hit return to enter the Desktop folder.

#3 Type “mkdir osxapps_local” and hit return to create the root directory of the same name on Desktop.

#4 Go to the newly created folder by typing “cd osxapps_local” and hitting return.

#5 To create the relative path inside the root folder, enter the following command: “sudo mkdir -p ./apple-assets-us-std-000001/Purple3/v4/74/d2/82/74d28291-9db9-7ae2-305d-9b8b3f5fd463/”. Provide the admin password when prompted.

#6 Copy the source package (ftk3252456602304584541.pkg) file you have downloaded earlier and paste it in the last folder of the directory tree created within the root folder. Click on Authenticate when prompted, and provide the system admin password.

#7 The Terminal prompt should be pointed to the root directory inside Desktop. Now, you need to host this folder on localhost. In order to do that, execute the following command in the Terminal prompt: “sudo python -m SimpleHTTPServer 80”. Provide the admin password and click on Allow in the subsequent message prompt. This will start the localhost server in the Terminal window. Do not close the terminal window till the process is over.

Start SimpleHTTPServer on Mac

To check the status of the local server setup, enter the URL of the original package in your browser and check the download speed. It should be very high as it is downloading from the localhost server.

El Capitan Direct Download at High Speed

Now, launch the Mac App Store and install OS X El Capitan in the usual way. MAS will now download it from the local server at a high speed. Once downloaded, you may proceed with the installation by clicking on Continue when the setup launches.

Note: During the installation process, your Mac may request resources from the “” domain. Thus, it is recommended to remove the entry from the hosts file before proceeding with the installation.

Is this method Genuine?

You might be wondering if this workaround to install OS X El Capitan is genuine enough. And to answer the question, it’s as genuine as the official method. Here, you’re downloading the same raw package that Mac App Store requests when it downloads OS X El Capitan. And you’re using MAS to convert the raw package into the executable app file. The only thing that changes here is the location of the raw file that Mac App Store downloads from (localhost instead of Apple server).

As for the build number, it is the latest version of El Capitan that was publicly released on September 30. Mac App Store downloads the update from a specific URL, and there is only one directory structure (with only one file in it) that you have replicated on the localhost server. If Mac App Store’s target URL did not match the relative path on localhost, it would not be able to download the package from localhost. After El Capitan has been installed, you may verify its build number (15A284) by clicking on “About This Mac” from the Apple Menu.

Additionally, we are also providing the MD5 and SHA1 hash values for the original disk image file (InstallESD.dmg) found within the processed OS X El Capitan app package. If you wish to download the raw package (ftk3252456602304584541.pkg) from alternate sources, such as torrents, you can verify the authenticity of the file using its MD5 or SHA1 (also provided below).

El Capitan (15A284) hash/md5


SHA1: 5e21097f2e98417ecc12574a7bb46a402594ea4a
MD5: d54b388282228df41f40e95649e8bc32


SHA1: 8ff3e26ec16aece573b3cea680b0df67f85ccd8a
MD5: f46f412a5a74b0122ac1a317d604758a

El Capitan – Single Download Multiple Installations

If you or any of your trusted peers have already downloaded the raw package on any other device, you can simply copy the file to your own Mac and upgrade to El Capitan using the above method. Moreover, if you have multiple Macs registered with the same Apple ID, you can directly use the processed app package created by Mac App Store on a single device, to install El Capitan on other devices.

Once MAS has finished downloading the setup, just go to the Applications folder and keep a backup of the “Install OS X El” file. To install El Capitan on other Macs registered with the same Apple ID, copy the file to the Applications folder of that computer and double click it to run the setup. You may also create a bootable USB installer for OS X El Capitan from the installer app package.

Direct link for 10.11.5

for MacOS 10.11.5, there is a secondary file (.pfpkg) needed.……

There are now 2 files for the OS, you will need to create 2 separate folder for both the files.


So, now that you know how to get the direct link, from now on, you can  generate the direct links for all the future releases.

Dual Boot Setting for OSX El Capitan and Windows10 

Now you have Windows But you are not able to Boot to OSX El Capitan due to Missing Boot Entry , now we gonna Fix This ::

Step 1: Run EasyUEFI   and See which Boot Entries are available , now we gonna add Missing Entry for OSX Bootloader ( Clover Bootloader ).

Disk0 is usually the internal Hard Drive / SSD. In the Boot order section, we can see that only Windows Boot Manager is detected. There is no mention of Clover UEFI anywhere.

EasyUEFI Setting

Step 2: To solve this problem, click on the Add button (the second button you see on the right).

EasyUEFI Settings 2

Step 3: Now Change Type fromWindows BootManager to Linux or Other OS , Type Name in Description Box (Whatever you want Clover Bootloader or Mac OSX Bootloader or Else depends upon you),  and Click Browse Button

EasyUEFI Settings 3

Step 4:  Now Expand EFI => BOOT or CLOVER Folder , Select any of Bootx64.efi or Cloverx64.efi  , Both are Clover Bootloader files Choose one or add Entry for Both but one is Enough to Boot Clover then why you waste your time but if you having Issue with and Then Use Another Option.

EasyUEFI Settings 4

Note : Remember these things :

1.Bootx64.efi is Bootloader file (this file is from Clover Bootloader )

2.Bootmgfw.efi is Windows Bootloader

3.Cloverx64.efi is Clover Bootloader

initially when we Click on drive to Boot it loads Bootx64.efi First then Required Files to Boot to OS (Operating System) . Every OS Contains it Bootx64.efi , Windows and Linux too . above Bootx64.efi is from CloverBootloader but anyhow your file is got Replaced with particular OS then Bootx64.efi will load that OS only .Clover is capable of running any OS.

But Don’t Worry use Above Bootloader Files to Boot to OS what you want .

Now Everything is done and you have Successfully added Boot Entry for OSX El Capitan in BIOS , Just Select This Entry and Boot to OS you want .

You will See Boot Menu Like This :-

Asus UEFI BootMenu

Also You can Set you OS’s Priority . you will see like This :-


Additional Workarounds :

These Following Steps i used to Format my Single HDD to Dual Boot in Mac OSX DiskUtility .

OSX El Capitan DiskUtility is not providing option to set you HDD as Free Space (as we were have in Yosemite or before OSX Version)

i have HDD (500 GB ) 250 GB for OSX El Capitan  and 250 GB for Windows 10 .

if you set you HDD first 250GB as Mac OSX and Second 250 GB as FAT32 or ExFat , This Way OSX WIll make Format your HDD as Hybrid GPT , there’s only way to Format you HDD as OSX Journaled to get Full GPT Drive .

Window 10 Can’t be Install on HyBrid GPT Drive you will Receive this Error Continously :-

Windows Error

Solution to This Error :-  

1 :  I Used Mac OSX Yosemite USB installer and Fomatted My HDD as

First 250GB for OSX  formatted as OSX Journaled and Left 250 GB as Free Space .

Free Space will be as Unallocated Space in Window10 Installation Disk Management

2 : You Can use GptFDisk to Convert your Hybrid GPT Drive into Pure or Full GPT then Windows Installation Can Proceed .

Pure/Full GPT Disk will look like :-


Above Screenshot is from Gdisk you can use Partition Manager Softwares on Windows as well as OSX to Determine Drive is Full GPT or Hybrid GPT .

Note : In My Case i was not able to Convert Hybrid GPT Disk using GDisk , receiving too many error then i used solution 1 , which is much Easier .

Things to be Remember Always Before Dual Boot:-

1. Always Install Install OSX First on HDD , Don’t try to Install Windows First .

2.EFI Partition is Required for UEFI Bios System , if EFI is not Present then it not Booting UEFI is using Legacy Boot.

3.Disable Secured or Set it to Other OS in Bios Menu , otherwise you won’t able to Boot from any OS then Windows .

Never try to Install Windows First Because Windows always make first partition as OEM (100MB), Second EFI (100 MB) and Third MSR (620 MB ).

OSX always Requires EFI to be First Partition and of (200 MB) at least of Size , otherwise you will Receive this Error Continuosly . Error will look like this :-

MEDiaKit reports partition (map) too small - Error

PS: This Guide is not only for Dual Booting With OSX El Capitan with Windows10 , you can Dual Boot any Version of OSX and Windows (UEFI Support ) on Single Hard Drive using This Method .

Guide for Installing OS X on Lenovo IdeaPad Y510p



Always visit the original source as that will be more updated. This is just for my reference.


  • This guide will always be incomplete (this is not a mac anyway) and I will refine it overtime time as needed
  • This guide is intended to help the very newbies having Lenovo Y510p to taste either OS X Yosemite (10.10.x) or OS X El Capitan (10.11)
  • As some may have different partition layout or different hardware, it should be noted this is not a definite guide and you must adapt according to the situation you have
  • For every step there might be other ways to do it better (or worse). The experts here in this forum may not agree with some of the steps mentioned here. This is what I had to do to get it working for my liking but comments and suggestions are very welcome indeed.
  • The work introduced here is gathered and collected from many sources. My contribution is the least of all and I will try to give credit where it belongs as much as I remember. For any work I forgot to give credit I apologise for not remembering the source.



What Works and What Does not (for both Yosemite and El Capitan)
Simply put, almost everything works if the post-installation fixes are followed carefully. In summary:

What Works  :thumbsup_anim: 

  • Graphics with full acceleration QE/CI (using Intel GPU only)
  • Audio using AppleHDA
  • HDMI Audio
  • Ethernet (LAN)
  • WiFi / Bluetooth (after replacing the Intel card (incompatible) with a compatible one like Broadcom BCM4352 for example
  • Sleep (also sleep on Lid Close)
  • Brightness
  • Battery
  • Keyboard / Touchpad
  • CPU Power Management
  • Web-Cam
  • All USB ports

Issues and What does not work  :thumbsdown_anim: 

  • Intel GPU / Restart issue: There is a problem related to graphics occurs when display goes off then on, like when system sleeps and wake for example, which results in no display on restart. More details and a workaround for this problem are introduced in Post Installation / graphics section.
  • Wake on LID open: Currently is not working but I believe this one can be fixed.
  • Nvidia GPU (built-in): This will have to be disabled as OS X does not support Optimus technology.
  • Nvidia GPU (external/ultrabay, for those who have it): This will have to be removed before using OS X. It was possible to boot with this GPU and the built-in Nvidia GPU without Intel GPU like it is possible in Windows / Linux. However, there are issues prevents configuring those Nvidia GPUs correctly. There is a work started inthis thread to try booting OS X with this graphics configuration but the work is in very early stage and seem halt as well as the interest of the community is quiet low for this regard.

1. Introduction


This guide intends to help installing OS X Yosemite and El Capitan on Lenovo IdeaPad Y510p. There are many ways to install OS X on this machine but I will focus only on vanilla installation and only UEFI. So no myHack, no niresh, no iAtkos, no U-Beast, no what so ever with all respect to the developers behind these tools and distributions.

Lenovo Y510P released with different configurations and is adjustable. My model have the built-in Hard Disk Drive (SSHD 1TB+8GB Cache SSD integrated) in addition to second Nvidia graphics card in the caddy. In Windows with the second Nvidia GPU present we see no trace of intel card which means the first Nvidia (the built-in not the external) is apparently attached to the display in a configuration that OS X do not know so the only option for now is to skip both Nvidia GPUs altogether. Therefor, the external Nvidia GPU must be removed and the switchable Nvidia GPU (Optimus) should be disabled, to prevent other problems, either via BIOS or by DSDT/SSDT patches.

There are many ways to dual boot Windows and OS X on Lenovo Y510p (and in general). In this guide I will stick with having Windows installed first in UEFI mode because this what any one would have initially once he buy this computer. At the beginning when I start writing this guide I only had the HDD and wrote that those who have SSD inside should not have any problem to adapt. Now that I have an SSD and booting off from it I will add it to the guide as well although nothing much would change.

For those who think of doing like me (i.e. to get an SSD to put both Windows 8.1 and OS X and their apps on it and keep the HDD for data only), you first have to put the SSD in place of the HDD inside (to benefit from the connector speed). Normally you either don’t have a place for the HDD or you are using a caddy but in all cases I suggest and advice to leave the HDD outside and work with the SSD only for now. Now you can proceed with the guide just as if installing on HDD with only one exception which is to fix TRIM after installation (explained later in the guide).

Since Lenovo Y510P have Windows installed in UEFI mode, I will simply install OS X in EFI mode and use Clover EFI bootloader to be able to boot either OS since both would be installed in EFI. A problem that we might have for such type of configuration (both Windows and OS X in EFI on the same HDD) is that OS X needs bigger EFI partition than that created by Windows (assuming Windows is installed first). In this case, OS X installer will refuse to format the partition we prepared for OS X installation. We have to sort this problem out before trying to install OS X at all.

This guide is split into several parts. First we create a space to install OS X in. Next we modify the size of EFI partition to remedy the mentioned problem. We then prepare a USB installer for OS X and use it to install. Finally we do some post-installation fixes to have more juice from the system.

Are you ready? Let’s go …

2. Preparing a Partition for OS X


There are many ways to do this, the easiest is to use Disk Management in Windows to shrink the last partition and create a new one in the space. Any other partitioning tool can be used for that matter.
My HDD was partitioned to have EFI partition, MS reserved partition, MS recovery partition, Windows partition, and Data partition. I used Disk Management in Windows to shrink a partition and free some space, then formatted that partition and labeled it “MacOSX”. The size of that partition is optional but I suggest to have it no less than 50GB to allow space for apps to be installed later on OS X. The label is optional too, we just need to keep record of that label so we don’t accidentally ruin any important partition later. Once we have the partition formatted (either fat32, exFat, or NTFS), we can proceed to the next step.

3. Increasing EFI Partition Size


As I said above, there’s a problem when trying to format the created partition for OS X while trying to install it. OS X will fail to format the created partition (we labeled it “MacOSX”) as HFS+ because of small EFI partition size since OS X requires big ‘enough’ EFI partition. So before attempting to install OS X, we’ll have to increase the size of that partition.

A default install of Windows 8.1 creates ~300MB Recovery partition, ~100MB EFI partition, and 128MB MSR (Microsoft Reserved) partition. This process (originally byRehabMan and slightly modified by me) removes the mentioned partitions and creates bigger EFI:

  • Boot Windows installer USB (you should have one ready of course)
  • Press Shift+F10 for recovery command line
  • Type: diskpart
  • Type: list disk (verify disk 0)
  • Type: select disk 0
  • Type: list part (you should see all partitions)
  • Type: select part 2 (part 2 is EFI part)
  • Type: assign
  • Type: list vol (to find out the drive letter assigned to EFI and Windows partitions, lets assume they were E: and C: respectively)
  • press Shift+F10 for another command prompt
  • Type: robocopy e:\efi c:\efi.bak /mir
  • Switch back to original command prompt (the one running diskpart)
  • Type: select part 1
  • Type: delete part override
  • Type: select part 2
  • Type: delete part override
  • Type: select part 3
  • Type: delete part override
  • Type: create part efi size=528 (the space left by removing all three partitions Recovery, EFI, and MSR)
  • Type: format quick fs=fat32 label=”EFI”
  • Type: assign
  • Type: list vol (to find out new drive letter, assume it is F: )
  • Switch back to other command prompt window (the one just running cmd)
  • Type: robocopy c:\efi.bak f:\EFI /mir
  • Type: exit
  • Switch to original command prompt (the one running diskpart)
  • Type: exit
  • Type: exit
  • Hit: Alt+F4 at the Windows installer to quit

Steps from 1 to 12 create backup of EFI partition contents so we can restore the contents after creating a bigger EFI and have Windows bootable. Then 13-18 it removes all three partitions Recovery, EFI, and MSR. Step 19 creates a new EFI partition with arbitrary size (put 528 which is the sum of previous EFI, Recovery, and MSR sizes). Step 20 format and label the new EFI partition, and finally step 24 restores EFI partition contents from the backup we created earlier.

At this point, I verify that Windows still boots and it should. Now I have 4 main partitions EFI, Windows, Data, and “MacOSX”.

4. Preparing OS X USB Installer


There are many guides on the web to do it, I will use virtual installation of OS X on windows to create the USB installer. If you have a working OS X somewhere else you could use that too. The USB should be no less than 8GB and you should have downloaded Yosemite/El Capitan Installer App from AppStore, ShowHiddenFiles app, Clover EFI bootloader, CloverConfigurator, HFSPlus.efi, FakeSMC.kext, and VoodooPS2Controller.kext / SmartTouchpad.kext. All these are available in Downloads section near the end of the thread.

The following are the steps to create the USB installer:

  • Plug the USB in and mount it in OS X.
  • Open Disk Utility, select the USB from the list, click on Partition tab, choose 1 partition in Partition Layout, click options button, choose GUID Partition Table, and click Apply. You can format the created partition in the USB as Mac OS Extended and label it as “MacOSX Installer”. Selecting GUID scheme creates a hidden EFI partition on the USB so the USB actually contains 2 partitions with only 1 visible.
  • Run ShowHiddenFiles app and click “Show Special Files”
  • Go to Applications folder and right click the Yosemite/El Capitan Installer App > Show package Contents > Contents > SharedSupport > and mount InstallESD.dmg. This will mount a disk labeled “OS X Install ESD”.
  • From the new window appeared, right click BaseSystem.dmg and choose Open. The image will be mounted as “OS X Base System”.
  • Go back to Disk Utility and Restore the disk “OS X Base System” to our created USB partition “MacOSX Installer”. Close Disk Utility once it is done, we are not going to need it anymore.
  • On the desktop there will be 2 disks with the label “OS X Base System”. One of them is mounted from BaseSystem.dmg and the other belongs to our USB which is the larger one. Rename the larger one to “MacOSX Installer”.
  • Now open the disk labeled “OS X Install ESD” on desktop and copy both files BaseSystem.chunklist and BaseSystem.dmg to the root of “MacOSX Installer”. Also copy the folder “Packages” to “MacOSX Installer” > System > Installation after removing the link with the same name there.
  • Start installing Clover on the USB (the partition “MacOSX Installer”) with these options:
    • Install for UEFI booting only.
    • Install Clover in the ESP.
    • Themes > BootCamp (or whatever)
    • Drivers64UEFI > EmuVariableUefi-64, OsxAptioFixDrv-64, PartitionDxe-64

Once you are done, you will find a disk labeled “EFI” belongs to the USB (the hidden one now visible). Open that, “EFI” > EFI > Clover, and using any plist editor (PlistEdit Pro is prefect) or CloverConfigurator app, edit config.plist with the following and save the file before closing it:

  • ​​ACPI > DSDT > Fixes > Remove All
  • ACPI > DSDT > DropTables > Remove All
  • ACPI > SSDT > Generate > CStates > false
  • ACPI > SSDT > Generate > PStates > false
  • Boot > Arguments > -v dart=0 darkwake=0 nv_disable=1 kext-dev-mode=1
  • Devices > FakeID > IntelGFX > 0x0
  • Graphics > Inject > Intel > true
  • Graphics > ig-platform-id > 0x0a260006 (you can try others)
  • SMBIOS > (set it to MacBookPro11,1)
  • Replace “VBoxHFS.efi” with downloaded “HFSPlus.efi” in the folder “Drivers64UEFI”.
  • Copy the two kexts downloaded (FakeSMC.kext and VoodooPS2Controller.kext / SmartTouchpad.kext) into Kexts > 10.10 (or into Kexts > other).

Now the USB installer is ready for prime time.

5. Installing OS X


In this section we shall use the USB to install OS X but first let’s edit couple of settings in BIOS. Shutdown the computer and press the novo key (on the left) and select to enter BIOS. From there, disable discrete graphics card (Nvidia) and disable secured booting. Exit saving changes and press F12 once Lenovo logo appears.

  • Select the USB from the Boot menu that will appear.
  • Clover will load in seconds, select “Boot from MacOSX Installer” and hit enter.
  • In a minute or two the installer will be ready. Format the partition prepared earlier as “Mac OS Extended (Journaled)” and install OS X. The computer will restart after installation is finished.
  • Boot again from the USB and this time select to boot from “MacOSX” entry.
  • The installed OS X will run and you should have touchpad and keyboard working. Use them to finish the first time initialisation and creating the account.
  • Install Clover almost the same why you did while creating the USB installer but with small changes to be made:
  • Tick “Install all RC scripts on target volume”.
  • Tick “Install Clover Preference Pane”.
  • Also edit config.plist to reflect these:
    • ACPI > SSDT > SortedOrder > List the order of the SSDT’s (normally they should be SSDT.aml, SSDT-6.aml, SSDT-7.aml to match the tables names in BIOS. The AutoPatcher will return different names but rename the files accordingly)
    • Boot > Arguments > dart=0 darkwake=10 kext-dev-mode=1
    • Devices > FakeID > IntelGFX > 0x04128086
    • SMBIOS >
      • iMac14,2 should be OK but it is usually for desktops
      • MacBookPro 11,1 without issues (in the past this SMBIOS used to be problematic with Firefox-flash but not anymore).
      • MacBookPro 11,2 will generally work nice but with few-seconds delay for touchpad upon booting for those who have Synaptics touchpad. If you have Synaptics touchpad try to avoid this SMBIOS and use any one of the other two but if you have ELAN touchpad there is no problem reported.
  • Restart and boot from USB, select “Clover Boot Options”, and choose “Add Clover boot options for all entries”.
  • Restart without USB and Clover will boot off the EFI partition and you can boot straight into MacOSX.

6. Post Installation
Once logged in, you will have a working system with full resolution 1920×1080 but with glitches and only 7MB (check Apple-Menu > About This Mac) which makes the experience awful. Also no Sound, no WiFi, no Brightness Control, no Battery Management, no Sleep, and more. Follow the steps below to fix most of the issues and have a better working system. Many of these steps will require DSDT/SSDT patching to get things working and these patches are not covered in this guide. Instead, I really recommend the reader to visit this awesome guide by intruder16: DSDT/SSDT Auto-Patcher for Lenovo Y510p Ideapad. It provides a brilliant method to auto patch all ACPI files with the required patches for our laptop without experimenting (which usually ends with error for newbies).

6.1 Graphics


Apple has removed support for Intel Mobile HD4600 and to make it work we have to fake OS X to pretend it is another supported graphics card and this can be achieved in several ways. The most recent and clean method to use is OS-X-Fake-PCI-ID by RehabMan and I advice everyone to read about it in this topic and carefully apply the method. Moreover, there are two additional things that should be covered here to fix some graphic glitches.

6.1.1 Enabling QE/CI
In brief, this is what should be done to fix the graphics and enable QE/CI:

  • Download, un-compress, and install FakePCIID.kext and FakePCIID_HD4600_HD4400.kext in /S/L/E or Clover kexts.
  • Add 9MB cursor framebuffer patch in Clover (as described in the linked topic) to fix few glitches that often appear when using ig-platform-id = 0x0a260006.
  • Setting FakeID for IntelGFX of 0x04128086 either in Clover or by patching DSDT

6.1.2 Fixing 16-bit colour (gradients)
Normally, OS X will run in good colours after enabling QE/CI. However, it was found that anything sets the display off then on results in dirty graphics that have colour gradients as described in this topic. Some examples of the actions that reproduce this problem are:

  • Putting display to sleep (with system not sleeping)
  • Putting system to sleep: on system wake the display will have to return on from off state
  • Changing system resolution: the display have to turn off then on
  • Connecting an external display: the internal display have to turn off then on

These events requires re-initialisation for the graphic driver but it seems the driver re-initialise incorrectly. As a result, the graphics related memory hold wrong data for some graphic registers which indirectly affects the restart functionality. Once the system is restarted in any of these scenarios, the POST (where Lenovo logo should appear) has no display and so is Clover and beyond if an OS is selected and booted using keyboard blindly. However, this is a graphic driver issue and has nothing to do with power or reboot function itself.

To fix the 16-bit colour gradient issue, our forum member vusun123 suggested using a custom EDID (google EDID if you don’t know what it is) and his suggestion workedbrilliantly. To apply the custom EDID, all you have to do is to add the following to Graphics section in Clover’s config.plist:

Note 1:
These are the lines to add and do NOT replace the whole section, apply common sense.
Note 2:
Although the custom EDID fixes the 16-bit colour issue, the restart side-effect is still there and needs a fix. There is a workaround though:

  • If you did not trigger the graphic-restart issue (no display off/on switch) then use Restart function as you wish.
  • If you triggered the graphic-restart issue then use Shutdown instead of Restart and Power on again. It is a good advice anyway not to hot-reboot between different OS’s as some devices do not initialise properly.
  • If you triggered the graphic-restart issue and used Restart already and stuck in a black screen, calm down and do not panic. Just know you are on Clover bootloader and control it using keyboard:
  • If you were planning to boot OS X, blindly choose it using keyboard and hit Enter. Now press Ctrl+Shift+Eject to set the display to sleep then press any key and the display will return. [Eject key is mapped to Insert for VoodooPS2Controller.kext users]
  • If you were planning to boot Windows, blindly choose it using keyboard and hit Enter and wait until Windows boots completely. Now press Fn+F1 to set Windows to sleep, then press any key to wake up the machine and display will be back on.

6.1.3 Fixing OS X boot graphic glitch
The following patch for IOGraphicsFamily.kext is required to fix a graphics glitch on second boot screen for Yosemite (10.10.2+) :

This one is for El Capitan 10.11:

There will still be a glitch in the transition between first and second boot stages which there is no fix for it at the moment. The only improvement that can be made is to enable Legacy Support in BIOS which will replace the transition glitch with black screen. Beware that enabling Legacy Support will trigger incorrectly initialization to graphic driver for OS X which will result in no display upon rebooting from OS X.

6.2 Audio


6.2.1 Enabling native AppleHDA
There are two methods to fix audio in OS X. The first is to use VoodooHDA which is a generic audio driver that support wider range of sound chips out of the box (acceptable with issues). The second method is to patch AppleHDA.kext for our audio chip to have native sound (better and clearer) which is a complicated process. Now that we have AppleHDA working perfectly, the guide will only offer using AppleHDA.

Getting AppleHDA.kext patched to work correctly for our Y510p indeed toke much time reading guides and trying things. I have to give Mirone the credit he deserve for his awesome guide and the patched kext he provided that enabled most of the audio features but not external mic support. Our forum member intruder16 did his best and succeeded to get this the right way. Basically what have to be done is:

  • Patching the binary of AppleHDA to support our audio chip (either in place or in Clover’s config.plist)
  • Adding the correct audio codecs to AppleHDA either directly or by using a helper kext to have all audio functions
  • Making a change in DSDT or in Clover’s config.plist to use the proper audio layout
  • There is also an additional kext to install to help restoring audio after sleep/wake

For those who want to learn (I recommend all to learn because this is why we are all here), you can find some good information in this post. Otherwise, head over Y510p-OSX-AppleHDA and use that script to create and install the helper kext. You will also find instructions on how to properly configure Clover so the audio solution is complete. From now on, these information will not be available in this guide to keep everything organized.
6.2.2 Fixing HDMI & HDMI Audio
Connecting the laptop to an external display through HDMI means the display will be responsible for audio output instead of the laptop audio system. This feature is broken on many hackintoshes (ours included) and here you will find the procedure to fix it:

  • Make sure AppleHDA is working
  • Patch the DSDT/SSDT that have the device at address 0x00030000 to rename it from B0D3 to HDAU. (the patch is included in Auto-Patcher)
  • Put FakePCIID_Intel_HDMI_Audio.kext in Clover’s kexts folder (optionally can be installed in /S/L/E)
  • Patch AppleIntelFramebufferAzul.kext for HDMI-audio (there are other patches for other configurations if this one did not work)
  • Set this option in clover’s config.plist:
  • Clear cache and reboot
  • Now when you connect the laptop to an external display through HDMI you will find new entry in System Preferences > Sound > Output for HDMI which means sound is now controlled by the external display.

HDMI Issues and workarounds:

  • If HDMI display is connected after OS X is booted (hot plug), the display will be distorted on the built-in display. This may need a new patch for AppleIntelFramebufferAzul.kext to get fixed but a workaround is to use the external display to change the built-in display resolution to anything then back to 1920×1080 again.
  • If HDMI display is turned off (or display mode is switched from HDMI) while OS X is running, OS X will freeze for second every few seconds. Turning the external display on (or switching to HDMI mode) again, or disconnecting the HDMI cable will fix the freezing and everything will be normal.

6.3 Ethernet (LAN)


To fix Ethernet we can utilize the solution by Mieze by first downloading the driver AtherosE2200Ethernet.kext (link in downloads section) then following the steps from his topic:

  • Goto /S/L/E and delete ALXEthernet.kext. (If you don’t have this it is OK)
  • Recreate the kernel cache.
  • Open System Preferences and delete the corresponding network interface, e. g. en0.
  • Reboot.
  • Install the new driver and recreate the kernel cache. I recommend to use Kext Wizard or a similar utility for the installation.
  • Reboot
  • Open System Preferences again, select Network and check if the new network interface has been created automatically or create it manually now.
  • Configure the interface.

6.4 Wi-Fi


The built-in WiFi card in Lenovo Y510P won’t work with OS X and I had to replace mine with Broadcom BCM4352 AC WLAN BT4.0 Wi-Fi card that is compatible with Y510P and OS X. For this card to work, OS X needs to see this card as one of those defined in AirPortBrcm4360.kext (inside IO80211Family.kext). Also, the same kext have to be patched to enable 5GHz.

PS: if you have other chip than mine or the given patch didn’t work for you, I advice you to visit Toleda’s topic to find all the up-to-date information.

6.4.1 Broadcom Airport Extreme
Put FakePCIID_BCM94352Z_as_BCM94360CS2.kext in Clover’s kexts folder (optionally can be installed in /S/L/E) and reboot.

6.4.2 Enable AC (5GHz)
There are 3 different Clover patches to try depending on the WiFi chip country. For me, the required patch is:

After putting the patch in config.plist, nothing more is needed but a reboot.

6.5 Bluetooth


In order to use BCM4352 Bluetooth with OS X, we will use BrcmPatchRAM to activate it. Head over Rehabman’s fork of BrcmPatchRAM (link in download section) and read how to install it. Basically, you will need to download BrcmPatchRAM and install two kexts from the archive depending on OS X version and install location.

  • For Yosemite 10.10.x: install both BrcmPatchRAM.kext and BrcmFirmwareRepo.kext in /S/L/E
  • For El Capitan 10.11: install both BrcmPatchRAM2.kext and BrcmFirmwareRepo.kext in /S/L/E

Ignore the rest of the kexts in the archive.

6.6 Proper CPU Power Management


This is important as it affects many aspects of the system specially sleep. To get proper CPUPM, either download and use the latest version of to produce CPUPM SSDT.aml (Secondary System Description Table), or, use the one generated by AutoPatcher. Either way, put the resulting SSDT.aml into EFI/Clover/ACPI/patched among other patched tables.

6.7 Sleep


At this moment the system might not sleep for many reasons like problems with USB, Network interrupting sleep, and not having AppleLPC.kext loaded on startup. If you are going to use AutoPatcher (recommended) then it will do everything for you and you can skip the rest of this section.

If you will go manually and still reading, I’ll try to cover all the requirements for perfect sleep but this will involve DSDT patches so you should be familiar with the process. You have to know how to use MaciASL, extract native ACPI tables (from Clover), disassemble tables using iasl, and fix common problems while patching.
The Laptop Patch Repository by Rehabman is a must have with MaciASL. Add it and it won’t harm to add his Debugging Patch Repository too.

6.7.1 AppleLPC.kext is not loading
This kext is essential for sleeping. To test if it is loaded or not fire off Terminal and issue the command kextstat then look for in the output. If it is there then the kext is loaded and nothing to do in this section. If not, edit your DSDT in MaciASL and patch it with “Haswell-LPC”. Reboot and use kextstat again to confirm AppleLPC.kext is loaded fine.

6.7.2 Fix EHC1/EHC2 Kernel Assertions
You can test if there are problems prevents sleep using the command pmset -g assertions. If you got anything with EHC1 or EHC2 then it probably USB related problem and you might need to patch the DSDT with “7-series/8-series usb” and/or “SMBUS Fix”.

6.7.3 Workaround for EHC1/EHC2/XHC Instant-Wake
If you got OS X to sleep but found it to wake immediately then look for wake reason in system.log using Console app. If the reason is found related to either EHC1, EHC2, or XHC then the easy workaround is to delete/comment the code related to powering on/off to these devices from DSDT which is the name _PRW for each of them.

6.7.3 Sleep on LID close
Out of the box LID open/close is not functioning. A workaround is available in Rehabman’s laptop patch repository and also in AutoPatcher that remove _PRW for LID but this method completely break the functionality of Wake on LID open. Since Wake on LID open is not working at the moment either way, this workaround is all what we have now.

6.8 Brightness


Getting brightness to work perfectly is a process of several steps that I’ll cover in order of importance:

6.8.1 Patching DSDT or SSDT
Skip this if you have used AutoPatcher. Either DSDT or one of the SSDTs (whichever contains IGPU definition) have to be patched with “Brightness fix (Haswel)” from Rehabman’s Laptop Repository. Doing this correctly will result in having the brightness slider visible in System Preferences > Displays.

6.8.2 ACPIBacklight.kext
This is a must have kext that gets the job done assuming DSDT/SSDT is already patched. With this kext the brightness slider will function normally.

6.9 Battery Management


This one is important but easy to fix, just download the latest version of “ACPIBatteryManager.kext” and put it in Clover’s kexts folder, reboot.

6.10 Keyboard and Touchpad


In this section I will cover how to activate the keyboard and touchpad. Moreover, I will show how to control brightness using Fn+Up and Fn+Down.
6.10.1 Activating Keyboard and Touchpad
There are two variants of Ideapad Y510p with regards to Touchpad so each variant will require different Kext to enable PS2Controller:

  • The first one with Synaptics touchpad and basically VoodooPS2Controller kext by RehabMan is great and reliable. In addition, EMlyDinEsH updated his SmartTouchpad kext so now it works very nice with Synaptics Clickpad available on Y510p with more features and it is worth checking out (both links in downloads)
  • The other one with Elantech touchpad and the driver by EMlyDinEsH is the only option which is great anyway for this hardware (link in downloads)

6.10.2 Controlling brightness using Fn+Up and Fn+Down
At the moment, you can control the brightness using the slider in System Preferences > Display. To get the default key combination for Y510P working we cannot use Karabiner or OS X shortcuts as the events are buried deep down. Therefore, the DSDT have to be patched and ACPIKeyboard kext by RehabMan may be required. (link in Downloads)

We will use Auto-Patcher for this:

  • If you have Synaptics touchpad and are using VoodooPS2Controller then choose Synaptics when prompted by the Auto-Patcher script. You don’t need ACPIKeyboard kext in this case as the needed functionality is built into VoodooPS2Controller already.
  • If you have Synaptics or ELAN touchpad and are using SmartTouchpad kext by EMlyDinEsH then choose ELAN when prompted by the Auto-Patcher script. In this case, however, you will need ACPIKeyboard kext as the needed functionality is not built into SmartTouchpad.

The above part may be confusing but I will update it once intruder16 update his script.

6.11 Enabling SSD TRIM


For those who are using SSD the OS should support TRIM which is a technology to removes any deleted file completely to enhance SSD performance and increase its lifespan. It is said that newer SSD have their own built-in technology to do this without any effort from the OS but not-so-new SSD’s does not have this. To get OS X Yosemite to offer TRIM support to our SSD, we have to put this patch in Clover’s config.plist:
And reboot the system.

6.12 USB 3.0


[Yosemite] Both USB 3.0 ports will work OOB but may not power on again after wake from sleep (at least with 10.10). To fix this issue, we will patch AppleUSBXHCI, the native usb driver, with just one patch through clover:

[El Capitan] I have used the same patch for 10.10 with 10.11 without a problem but I noticed that all USB devices are routed to USB2 controller with that patch active. Without it, El Capitan will still route them to USB2 controller until system goes to sleep then wake. Thereafter, USB3 controller will handle the devices without routing. There is a technical situation here and I’m investigating it but despite that, all USB ports will work no matter that patch is applied or not. You can choose to use the patch above with 10.11 or not, it’s up to you, until further notice.

Need HELP??  :help: 


  • Make sure you have CAREFULLY READ the entire guide. I have the same laptop as yours (mostly) so it is unexpected to have unique issue unless you have a faulty machine.
  • Search the topic (and the web in general) for the things you have questions about before asking. The answer for your question may be few posts away so save your time and other’s.
  • If you still want to ask for help, you are welcome but you have to know that no one here have super powers to sense the problems without details. Some problems are well-known and small amount of evidence is enough for diagnosing them but many problems are not. Therefore, in general, this is my advice whenever you try to report a problem or ask for help:
    • Introduce the problem in clear words
    • Provide as much information as you can in form of logs, screenshots and/or dumps
    • State whether the issue is reproducible and list some of the ways to reproduce it.
    • State the things you have tried and the results you found
