Hi. I got problem to run r9 290x under sierra. I got full HD resolution but is glitche and no acceleration. On my second OSX Yosemite r9 290x working fine. Any solution for me?
Inject ATI is "true" ....do I need patched 8000 for sierra or add to clover some ati patch?
 
Hi there, your Graphic Adapter must work OOB, remove all ati related injection and see if macOS detects it or not. If it's not recognized by macOS without any injection use Baladi framebuffer with Inject Ati=true.

Remember that sierra might boot to black screen which is a known issue with AMD cards and needs a helper card such as IGFX to be set as primary in BIOS with no injection for Intel and ATI and the display connected to AMD card.

if your mother board doesn't have intel integrated graphics you'll defiantly need another supported helper card to be set as primary.

Yes i tested all Framebuffers- no results. Always recognised as R9 290X 7MB. Without "inject ATI" is Unknown 7MB.
On Yosemite is working fine and is recognised as 8xxx
