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
A setup with an IVY bridge e5430 dell worked fine. but now seems the XHC device
is a hardware issue. There is no bios setting to enable disable. Only enable/disable boot/external.USB in general.
All set to enable. Also just mention of USB in power settings wake on USB.
Did show up when I set up the ports w/USBINJECTALL, then was working on imessage isssue when the DSDT
stopped loading after updating clover. I had two versions of MAcIasl. One with iasl 6. and one had 6.2a. Kept
the 6.2a, was RM's most recent. One problem Im confused by is it compiles fine but after saved if its opened,
the error that was repaired comes back.
If (LEqual (PM6H, One))
CreateBitField (BUF0, \_SB.PCI0._Y0C._RW, ECRW) // _RW_: Read-Write Status
Store (Zero, ECRW (If (PM0H)
CreateDWordField (BUF0, \_SB.PCI0._Y0D._LEN, F0LN) // _LEN: Length
Store (Zero, F0LN)
Loads with the error but not sure what happened on the original that worked.
Going over the boot log, The XHC device is there under the PCI readings dont think hardware issue... 1e31 Just seems the saved DSDT should not
have errors after saved, but using the other version of Maciasl, the DSDT would save without errors and open without but it would not load.
acted like there was no FakeSMC...
Edit: Seems all the saved DSDT have that error when re-opened using that version RM's Maciasl w/iasl v.6.2a but seems to load fine.
Hello, I am new here, so I apologize if I've chosen the wrong subforum for this question.
I am scratching my head a bit on an issue with a clients MacBook pro. He was having USB connection issues and claimed the laptop wasn't detecting any USB connected to it.
Figuring it was a failed USB port, I took it in but ended up just feeling more confused after doing some diagnostics.
It came in loaded with Catalina, a recent upgrade spurned the beginning of the issues the client told me.
I decided to revert it back to the default OS in the base recovery image, which is Yosemite.
Upon finishing the install, I found that the USB port was in fact working again. Figuring I had resolved the issue, I updated it back to Catalina just to be met with the same issue upon reinstalling.
Tried nvram, pram, and smc reset each to no avail.
One thing to note is that during boot, the USB is getting power as it lights up when connected during boot up.
But the ports are dead as soon as it boots into the operating system.
I have a strong feeling that this is a driver issue. I tried unloading and reloading the USB IO kext, with no noticable change.
Is anyone here familiar with this issue? Would there be any other kext related troubleshooting i can perform ? Is it possible to revert to the kext used in Yosemite on catalina ?
One last thing to note, on Yosemite the USB was functioning 100%. But I did get a strange notification that the USB ports were using power even when there wasn't any connected to it. Either way, I find it very very odd that it works perfectly in Yosemite.
Thanks in advance
I have successfully gotten my Hackintosh working 99 percent. The remaining issue that I am running into is that my system will randomly kernel panic upon a user issued shutdown or reboot WHEN I have either a usb sound card or usb headset plugged into any of my USB ports (both 2.0 and 3.0). If I remove the headset, it will power down with no issues. Does anyone have any suggestions?
My system is as follows:
MacOS 10.14 Mojave
Gigabyte H370 HD3
8400 i5 Coffee Lake
Radeon RX 580 sound card
