[Success] Radeon RX 6800 XT - Big Sur

[ARES777]

Am pleased support is on the way but ... Remember - no forum discussion of Developer Betas is permitted

11.4 beta 1 I KNEW YOU HAD IT IN YOU! (literally)

Looks like they've put it in X6000 after all, I was sure there'd be a X7000.

Bad luck you 6700XT guys if it's not supported Not mentioned in release notes and I only see Navi21Controller in the info.plist. Maybe that'll come soon.

My prediction done in 15th March "The size of Kexts for example X6000MTLDriver increased from version to version, like let's say 12.5 Mb upto 100+ Mb (public vesions). The size of other plugins changed a little in 3 public versions. So what I expect is, as previous speculation , those driver will be done after 1st April, or even later. Sorry for folks which want "Now" the driver. If the interest of Metal Support kext was lost, no, it was not. The increase of file tends to give me hope. So, let's wait for 11.4 (.x)and we will see later. " was good

Great news! Now I just need to find one in stock that doesn't have a 100% markup on the price

I am glad to hear this very welcome news. I had noted a few days ago that 11.4 might be the last version of Big Sur before WWDC and perhaps macOS 12.0 beta1 is released, and that support for the 6000 series would have to come in 11.4 if Big Sur was to ever gain support.

So it's very good to see Apple still breathing life into its x86 build of macOS!!!! If only they also support Rocket Lake, Alder Lake, etc... and the iGPUs within!

Once support can finally be confirmed in a public beta that we can talk about, the name of this thread should change from

[FAILED] Radeon RX 6800 XT - Big Sur​

to

[SUCCESS] Radeon RX 6800 XT - Big Sur​

6700XT is also RDNA2, so it should work. If not i'll just sell my 5700 and 6700 XT then buy 6800XT or even 6900XT

6700XT is Navi22 where 6800, 6800XT and 6900XT are Navi21.

Navi21/22 is just an chip generation id. Like Sky/Coffee/Kaby for Intel
Architecture (instructions set) is the same - AMD RDNA2.
Technically 6700 is a 'die shrink' version of 6800

So 6700 should work out of box (or require a minimal patch such as pci id / device name spoofing)

My fellow 6800xt users will be very pleased with 11.4.

Some of what you stated is true, but most important is the power delivery and the settings that the macOS drivers sets, as it has been pointed out, spoofing a 6700 to a 6800 gives instant reboot, most likely because of different power requirements.

If Apple went through the trouble of finalizing drivers for the 'big brother' 6800 and 6900 series, it's very likely that support for the 'little brothers' will also come, possibly in a future beta. Just my speculation.

Awesome news! Sounds like there will be a pro follow up event in June. Or maybe they will just do a silent update to the Mac pro configurations soon?
