I can't find any info on that card... Can't tell if it's Polaris or Baffin... 14 compute units or 16...

I think it has 14 compute units

If it's Polaris, it should just work. macOS should natively support it. There are no special settings for the GPU on my EFI folders. The only thing in my EFI folders that can affect GPU is WhateverGreen.kext.

So I should use iMac Pro SMBIOS and delete WEG kext? And Inject Intel for Hardware decoding?
 
def polaris arch and maybe 14 compute units.

I just checked my RX 560 and it's Baffin with 16CUs. So even Baffin should work with macOS built-in drivers.

iMacPro1,1 should be fine. If you use iMacPro1,1, you should disable IGPU in BIOS.

No, do not inject intel. Do not inject any of that stuff. The only thing you need to do with my EFI is populate the Serial, Board Serial, and UUID.

If you want to enable IGPU, change to iMac19,1 system definition.
 
Okay thanks! Would you prefer IGPU? Which performs better, with or without?

It depends... Most of the reports I read are from users who are using higher end GPUs such as Vega 56/64, RX 580, etc. With most apps, just using dGPU with iMacPro1,1 is fine. The one place where I see conflicting reports is with FCPX. Some claim having IGPU enabled is better, some claim IGPU disabled is better. I'm not a FCPX user so I can't confirm.
