[Success] AMD RX6000 Series working in macOS

Thanks for being so active on this!
Unfortunately, yet again, no dice.
The GPU still appears with "No Kext Loaded".

In the meantime, I've managed to install Windows and the proper drivers so I'll be toying around with that over the coming days.

I've done some more research as well and it turns out that there's currently no tool capable of extracting the VBIOS from the XTXH variants. As far as I can tell, a tool exists, but is not publicly available thus far.
The only XTXH VBIOS I've seen in the wild has been a leaked one.

As such I think it'll take a few weeks until the right people get their hands on these new cards to properly develop, test and actually release these tools. Until then, there's little a layman like me can do, unfortunately.

I think the best medicine here may be time.

Agreed. At least we've ruled out the straightforward remedies.

May the WEG guys find a way to make these work if nothing else.

Apple may officially add support for this and the 6700XT, which is NAVI 22 with device ID 0x73DF. I would expect the 6700XT to be supported, which means a future driver update may add more models.

Confirmed working 11.4 with ASUS reference design 6900xt!

Edit: Before updating to 11.4 - all I did was download the latest kexts and replace them in my EFI. No bootflags were changed from my previous Big Sur boot with a 5700XT

nothing special since support came with 11.4 beta 1

Anyone confirmed is 6800 6800xt 6900xt support 4k 120hz or 144hz in latest beta Big Sur? (assume display support 4k 144hz)

144hz confirmed working on my LG 27GL83A-B (1440p, not 4K) over DP with a 6800 XT. The monitor also claims adaptive sync is active but I'm not so sure about that actually being true.

So close to 190k... I havent had a single issue with the drivers. Typical apple, perfects their ways right before scrapping the entire thing and moving on to something else

4k/120hz Still not possible with bigsur 11.4.

Really hoping someone will find a fix for this.
