This 'straightforward' approach doesn't work for me.2. AMD Radeon Graphics Cards
AMD Radeon drivers are always included in OS X. You'll always find the most recent drivers in the latest OS X release, there's no other official place to download them. You might come across some patched or backported Kexts, but we'd advice against using them for stability reasons.
If you've ever installed on of those kexts, restore the original OS X drivers by reinstalling the latest Combo Update.
To get started, boot up without any graphics related settings in your config file:
Clover: InjectAti=False (FBName/VideoPorts unnecessary)
Chimera/Chameleon: GraphicsEnabler=No (AtiConfig/AtiPorts unnecessary)
If you have a OOB supported graphics card, OS X will boot with full acceleration. Done!
I recently purchased the Sapphire Pulse RX580, hoping to be able to change my NVidia GFX 950 and get a boot to Mojave from the High Sierra 10.13.6 OS I have running now. It's been a nightmare. I can't boot anything, USB Installer, the working OS SSD, nothing. It just freezes.
I have posted here, post 2588,
Radeon Compatibility Guide - ATI/AMD Graphics Cards
discussing the problem I'm seeing. No advice yet helps. It must be some simple Clover setting as this freeze occurs as kexts are being loaded.
Any help here?
