As I see many novices in the forum ask "How to make my Radeon working? I have bad resolution, no QE/CI...." and so on. They come to the section and have no find an answer here because all Radeons are different and they don't know where else they read about this.
I want to explain all steps needed for launching the Radeon family of videocards.
I will speak about Clover because I maintain this bootloader to know recent hardware and modern OSX. Not sure if you will have the same result with other bootloaders. I am carefully checking the injecting of ATI card and correcting it times to times. I am also accessible for bug reports.
Older card require older system, newer cards require new system.
ATIRadeon9000 is possible to launch under Tiger.
ATIRadeonMobilityX1400 requires 10.5-10.6. See RadeonHD topic.
As I see RadeonHD3xxx was successful only in 10.5
For new AMDRadeonHD7xxx there must be 10.8.3+ system.
This must be the first question before asking about the card.
You may know the device-id from Windows->DeviceManger->VideoCard.properties->compatibleIDs
You may boot into system in safe mode (key -x) and see system profiler
And you may boot into Clover GUI, press F2 and get preboot.log. Find here something like
2:709 0:000 PCI (00|01:00.00) : 1002 6758 class=030000 2:709 0:000 Found Radeon model=AMD Radeon HD 6670 Series It means my DeviceID=6758 (these are hex numbers)
Then you must check that Apple's drivers support your DeviceID. If not then add it!
For example HD7850 has DeviceID=6819. If we look into ATI7000Controller (AMD7000... in new systems) we find 6818 here but no 6819!
I show you how to do this with terminal commands. Launch /Application/Utilities/Terminal.app. Type in opened window:
cp /System/Library/Extensions/ATI7000Controller.kext/Contents/Info.plist ~/Desktop So you get a copy of the Info.plist on Desktop. Edit it with TextEdit. Change 68181002 -> 68191002.
Don't edit this file directly in the system folder!
Then copy back by terminal. Don't use finder to copy kexts! They will have wrong permissions in this case.
sudo cp ~/Desktop/Info.plist /System/Library/Extensions/ATI7000Controller.kext/Contents/ sudo rm -r -v /System/Library/Caches/com.apple.kext.caches/* Second command make sure next reboot the kext will use your edited info.plist.
The same operation you must do with a kext AMDRadeonAccelerator or ATIRadeonX2000 or other one. Check all candidates if they contain such list of possible IDs and choose closest to you.
Since Clover revision 1971+ you may just inject new DeviceID into DSDT instead of correcting kexts. See instruction here.
GraphicsEnabler or Injector
OSX needs to know some properties (Model name, Family, etc...) that must be somehow injected at boot time. Yes, also real Macs got DeviceProperties string from firmware.
1. Set InjectATI=Yes in Clover (same as GE=y in Chameleon).
2. Use custom string made with gfxutil. For whom who knows.
3. Write _DSM into DSDT. You should know what to write.
4. Use some kext like ATY_init.kext or Natit.kext. If you are sure that the kext is for your card namely.
I want to say that all this methods make the same thing. Differencies in their tuning.
The Clover do this automatically for most known cards at this moment.
As you may see to start HD5000-7000 some strange names used: Pithecia, Orangutan, Elodea... What are they?
They are configs for framebuffer. Predefined configs how connectors are solded for cards used in real Macs. Strange but these configs rear coincide with PC card. Usually gurus make advice "choose a framebuffer that most appropriate for your card". The chances 1:10. In most cases you may find a FB name that gives you main monitor working. Or nothing at all.
Great respect to bcc9 who gives us a method to correct one of config to be exactly for you. See here.
My retelling for Clover is here
Success example in the thread in posts 44-52
I tested Clover's methods with two users having Mobility Radeon HD5470 and HD5650M. We found that full memory and QE/CI will be achieved if we set in Clover's config
even thou no file with bios is provided. This is the key to make Radeon Mobility working!
Other problem is bad gradients or artifacts. For this case Clover accept the key
and sometimes you also need to inject CustomEDID.
See Clover instructions for details.
And my results.

for this card "yes" leads to black screen. Use with precautions.
A sample for Radeon R7 240
UPDATE for ElCapitan.
It seems has more problems. My HD6670 is not working in ElCapitan OOB unlike Mavericks.
I had to set FakeID=0x67401002 as correspond to real iMac12,2 and set this model in SMBIOS section.
It related to GraphicsPM or GraphicsControl.
Look these kexts to decide what you can do for your configuration.
HighSierra requires change these kexts by version from Sierra 10.12.6
for Radeon HD6xxx
AMDRadeonX3000.kext AMDRadeonX3000GLDriver.bundle IOAccelerator2D.plugin IOAcceleratorFamily2.kext . for Radeon HD7xxx and up AMDRadeonX4000.kext AMDRadeonX4000GLDriver.bundle IOAccelerator2D.plugin IOAcceleratorFamily2.kext . Black screen after wake problem resolved by follow method radeon_bios_decode.0.2.zip
Finally I finished the installation of 10.14.6 on my Dell E5440. Everything works just fine, but HDMI will not work. Every time I plug it in, it causes a grey screen on my laptop monitor. Also on boot up. I attached my EFI Folder, maybe someone can help me. I searched a bit and read something about Azul Framebuffer Kext.
Thank you for helping.
I decided to open this thread for Intel HD Graphics 530 SKYLAKE
This GPU seems to be problematic with Hackintosh , specially if you intended to use it with 4K monitor or Multi-Monitor .
Simply after you followed all the right instructions to patch framebuffer using Lilu.kext and WEG as described here in @headkaze
"Gen 6: Skylake (Intel HD Graphics 510-580)
- Support started with OS X 10.11.4
- device-id: 0x1916 0x191E 0x1926 0x1927 0x1912 0x1932 0x1902 0x1917 0x193B 0x191B
- AAPL,ig-platform-id (desktop): 0x19120000 (default)
- AAPL,ig-platform-id (laptop): 0x19160000 (default) "
Simply after Apple logo boot go to black screen
I can't use platform-id : 0x19120000 as suggested is a default
I am sure Bios settings is correct , Clover is correct , Kexts , ...etc
But end always with Black screen
I've seen a lot of people have the same issue when googling it , but no solutions at all
I want to know what is the reason that cause the black screen ?!!
Is 0x19120000 not default ?
@vit9696 WEG issue ?
Something else? @PMheart @vandroiy2012
FYI : using Displayport 1.2 , using HDMI = Black screen
Only solution is using Platform-ID : 0x193b0005
Now you can boot normally but Monitor in this case seen as TV NTSC
Is 0x193b0005 is the default Platform ID ?
Can someone help us please ?
I am looking for tips on how can I patch my FrameBuffer to be able to use mobile ig-platform-id for HD 4600 Intel Graphics. ATM the only way to have recognized full resolution and memory (1,5GB) is to use 0x0d220008 desktop Haswell profile.
Problem is that on this profile backlight patches do not work. I get blank screen during boot instead of apple logo.
As RehabMan suggested in my debug topic, this is possible because of the fact that my laptop uses eDP to connect LCD, and that eDP is not fully supported. But as far as I've found T440 laptop's LCD is also connected via eDP and they work with backlight.
How can I debug / patch such situation?
I am new to hackintosh knowledge but want to make my laptop work so any suggestions and help is much appreciated.
