Radeon RX 6700 XT / RX 6800 / RX 6800 XT / RX 6900 XT for macOS
@basud, I have heard that Big Sur 11.2 has support for the new cards, but not hardware acceleration yet. So I'm hopeful it won't be too much longer.
I would think it a high certainty that Apple will support the 6XXX series. Until they have their own desktop GPU chip that outperforms AMD's best offering, for the Mac Pro to be a true "pro" Apple must offer support for the top AMD GPU's available. It's not exactly a huge deal in work hours to sort drivers out.
Driver ( kext ) is ready, Apple will support Radeon 6xxx soon.
It has been a month now without news AFAIK.
How soon is „soon“?
@jimmcq, Catalina recognises the GPU but with no hardware acceleration, just like Big Sur does... I wonder when it's gonna be supported
There's some progress with Big Navi in beta 11.3. While they are still not working, the RX 6000 series hardware ID [0x73BF1002] are in AMDRadeonx6000Framebuffer.kext. As @mac_editor has observed over the years, system update .4 is the one with major changes so my bet is that's when we see full support for RX 6800/6900 XT.
