Radeon Compatibility Guide - ATI/AMD Graphics Cards

Can someone tell me if my amd radeon r9 270 is compatible with any Mac OS I’m trying to build one and have had this graphics card just sitting here… thanks for any help in advance!
Did you look at the chart on the first page? It doesn’t seem to be working out of the box and the device id is listed as unknown.
 
Yea that’s what I was trying to dig through I didn’t really see anything beneficial on there

I think that list is outdated because after searching this site I found posts where people had faked the device I’d and made it work. Check out this thread here:

Besides my HD 7850 works for macOS out of box and is recognised as R9 270.
 
I would assume it is the same as the other non ‘X’ branded cards, ie. it requires a fake-ID to work in macOS.
 
Hi guys, I'm trying to install Catalina with Opencore but after verbose I see a black screen on HDMI output. The GUI works only on Displayport.
The solution, for me (according OP), seems to be injecting Hamachi framebuffer (instead of Futumaki), but how to do it in opencore?

My setup (Legacy BIOS):
Gigabyte P55a-ud4
i7-860 (Lynnfield)
Sapphire R9 280x Toxic (2 x minDP, 1 x HDMI, 1 x DVI) with ID: 0x67981002

Radeon_bios_decode/decoder didn't work on my actual Sierra Hackintosh (maybe due to legacy BIOS) but I extracted some info with AMD Framebuffer Utility (see photo attached) and Hackintool:

GPU Display controller:

Code:
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/pci-bridge@3/IOPP/GFX0@0
 
PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x0)

GPU Multimedia controller (HDMI Audio):

Code:
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/pci-bridge@3/IOPP/HDAU@0,1
 
PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x1)

Please, could you help me to create the right Device Properties to paste inside opencore?
Thanks a lot
