How to enable Intel HD4600 natively on your Hackintosh

If you’re Hackintosh has an Haswell CPU you’ll have by 70% of chances an integrated graphic card, the Intel HD4600. This GPU works perfectly with OS X because its present in some real Macs, like the MacBook Air and the entry level iMac, and you can use it with your Hackintosh without adding any modified or extra kext to the system. To use it you’ll only need to enable it with Chameleon or Chimera, that’s it.

Those two boot loaders in fact have a feature called “GraphicsEnabler” which, if enabled in your org.chameleon.Boot.plist file in your Extra folder, will automatically search and set the “Device properties” parameter for you to make your GPU recognized by OS X which will then load the proper kext according to the GPU model. But, since GraphicsEnabler is a completely automatic feature it has a few downsides. First of all GraphicsEnabler can increase boot time since it needs a few seconds to correctly identify your GPU using a few tests, second it can be wrong sometimes and/or with some particular GPU models, third your GPU could be recognized correctly but Quartz Extreme and Core Image graphics acceleration could not work.

Note: If you’re not a “pro” Hackintosh user and GraphicsEnabler correctly recognize your HD4600 already you won’t need to change anything since everything is working fine for you.

So, is there a way to enable the Intel HD4600 without using GraphicsEnabler? Yes, just follow those steps.

You will need:

  1. Download and extract all the applications
  2. Copy Chameleon Wizard and EFIStudio to your application folder
  3. Open the Terminal
  4. Paste this line in the Terminal window and press Enter
    ioreg -lw0 -p IODeviceTree -n efi -r -x | grep device-properties | sed 's/.*<//;s/>.*//;' > device-properties.hex
  5. With this terminal command a file named device-properties.hex have been created to your home folder, like in this picture:
    giuliolombardo-14
  6. Open EFIStudio and select Open Hext File… from the File menu
  7. Select the device-properties.hex and press Open
  8. Now you’ll see an “Editor” window with all the GPU informations, click on Hex String to Clipboard to copy the string, like in this picture:
    Editor_e_EFIStudio-6
  9. Open Chameleon Wizard and go to the org.chameleon.Boot tab
  10. Click on the Paste button in the Device properties section to paste the Hex string, like in the picture below:
    Chameleon_Wizard-5
    Note: EFIStudio will always copy a few spaces along with the Hex String, this isn’t always a problem for Chameleon and it should recognize your GPU anyway but, to be sure, delete all the spaces after the Hex String.
  11. Click on save to save the org.chameleon.Boot.plist file in your Extra folder.
  12. Reboot

Choose the best model number on your Hackintosh for correct power management

Choosing the model number for your Hackintosh setup is not a cosmetic reason, not the only reason at least. In fact the model number it’s a crucial parameter which “tells” to the operative system what type of computer you’re using. On a regular PC, with Windows or Linux installed, this is done automatically for the user during the OS installation based on a few conditions like: “Is this a Desktop or Laptop computer?”, “Which CPU and GPU model it has?”, “Is the GPU integrated or not?”.
The same thing happens on a real Mac computer but the only difference is the fact that when OS X is being installed instead of “asking questions” it simply reads the answers which are contained in the EFI portion of the Mac, and, since there are only a few fixed types of Macs [iMac, MacBook Air, MacBook Pro, Mac Pro and Mac Mini], this is a simpler process compared to ordinary PCs.

While this is a straight-forward process for a real Mac it can be a problem for Hackintoshes since there are not fixed types of computers and anyone can built it’s own setup with different components like a normal PC. Another problem is that OS X’s power management is completely based on the model number parameter and, as you can easily understand, if it is wrong it will be wrong too.

So, how can we fix this problem? By using the SMBios.plist file.

This file, contained in your Extra folder, holds many informations about your system such as its serial number, BIOS version and the one we’re looking for: the model number.

Note: The SMBios.plist is a really [really!] important file and you cannot simply change it without knowing what you’re doing. Remember that the system uses this file to initiate and pass data to system kexts as needed.

To edit the SMBios.plist we will need Chameleon Wizard, download the latest version available here, install it by dragging it to your Application folder and then open it. Once Chameleon Wizard is launched click on the SMBios tab and then click on Edit

You could ask: “Which model number should I choose?”, answer: the one with the most similarities with your build with CPU at the highest priority. For example if you have a Haswell CPU choose a model with Haswell CPU [desktop or laptop depending on your system], if you have Ivy Bridge select a Ivy Bridge model an so on.

In my case I have an Intel Core i5 4570S and I have chosen the iMac 14,2 model number since it has the same CPU [as you can see here] so power management will work perfectly.

If you can’t find any model number similar enough you can try using MacPro 3,1, it’s the most flexible model number and it can work sometime with unsupported hardware.

Remember: Chose your model number based on your CPU, if you need help with Mac models you can use the Apple official tech specs websiteEveryMac.com, or Wikipedia
