ydeng Posted September 6, 2017 Share Posted September 6, 2017 Need to set fakeID 0x68181002 and set Radeonframebuffer? Set GraphicsEnabler to No if you use Enoch. Likewise with Clover. I don't know if you need to fake pci id. People say 270x works out of the box, http://www.insanelymac.com/forum/topic/305543-does-the-r9-270x-work-on-yosemite-10103/?p=2126955 Quote Link to comment Share on other sites More sharing options...
