AMD R9 290X on High Sierra

[SkinlessGaming]

Hi,
I was just wondering if AMD R9 290X is compatible with High Sierra? All my other hardware is compatible as I tried it before on a different AMD card and it worked perfectly. But since I've upgraded to my 290X, it hasn't worked in previous versions of macOS.

Hoping someone can help

Yes, it's compatible with High Sierra. You just have to set RadeonDeinit=true in latest clover (4296+) and it will work out of the box.

Thanks for that. i managed to get through the installer, but i’m stuck at a black screen before OS startup. do i need to inject ATI/FakeID?

I didn't set ATI injection nor fakeID. Did you disable your integrated gpu? You also need to check if you have UEFI bios on your radeon, I think it won't work with legacy bios...

I have a UEFI bios and installed macOS in UEFI mode.

I think I could still have iGPU enabled. i’ll disable it when i’m home and report back

What @Pabloesc is asking you is does the graphics card have a UEFI vBIOS. To test to find out disable CSM in your UEFI/BIOS settings.

That was the issue - CSM will enabled. It worked and I'm running macOS Sierra now! Cheers for your help guys

Okay, I've found another issue. When I boot up, I can only get into macOS if I have one screen plugged in. I can then plug in my other screens and they work fine.
Is there a way so I can always boot with 3 screens, as it's a bit awkward to get to my pc (under my desk)

You need to patch the framebuffer, I use single monitor so i'm ok with default framebuffer, read http://www.insanelymac.com/forum/topic/288601-patched-framebuffer-repository/
