[Success] AMD RX6000 Series working in macOS

MysticalOS · Mar 15, 2022

I hadn't taken issue seriuosly enough because people were only posting benchmarks. geekbench, opencl etc.

It wasn't until I fired up Metal game, opengl game and found that the computer struggled to get even 60fps on lowest settings when it was gettng 120fps on highest settings before update.

I can't emphasize enough to people of forum this is not just a benchmark issue, it's real application performance and it's reduced by far more than 50%, it's educed by like 75% for me in any game I tested. I even reached out to developer of one of games and they had me run some tests and they showed that a significant amount of unusual time is being spent on both cpu and gpu in the driver...They passed it onto apple who was like "eh, we didn't change anything, all we did was add device support for the new gpu option for mac pro".

That doesn't sound encouraging...But we shall see

Is there any indication that this is a problem on genuine Macs with 6800 or 6900 GPUs? Or is it isolated to Hackintoshes?

Just want to say, absolutely do NOT install 12.3

The performance bug is there in live release. My performance is literally crippled by update. WoW fps went from 120 to 40 post update, no settings changes, activity monitor shows cpu isn't an issue. it's like apple intentionally crippled the GPU

I don't want to say much at this point, but if it is the case there has been a performance downgrade for a Mac Pro compatible card right just before the M1 Ultra Mac Studio is released is telling us something...

Let me put it this way. I've certainly known through the years that just before a new macOS arrives, whatever previous OS I had installed on my setup like a Macbook, Mac Mini, Macbook Pro or even iPhone, the system would inexplicably slow down for no reason at all, right just before WWDC season. Apps would run slow, bootup would be slow, browsing would be slow etc. So for Apple to say they didn't change anything is kind of hard to believe imho.

There is a thread on a diff forums, but they don't really say what macs they have. It would not surprise me to be affecting any normal mac using an eGPU of these cards though..but in same right I've seen 0 complaints from any mac using AMD based gpus built in from 5xxx series....the intel mac pro is probably only question since it has some non consumer 6xxx gpu options.

I believe it does. Just been browsing on the Apple interwebs regarding 12.3 update and found this posted recently:

'I've done a bit of testing with Blender and the render performance was impressive on my 6800 XT on 12.3. It takes a good while (4-5 minutes) to compile the render kernel for the first time but once compiled, the Metal render performance was about 4x as fast as my M1 Pro 10-core CPU 16-core GPU Metal rendering on both the CPU and GPU in my tests. I don't recommend updating though because overall system performance and snappiness takes a HUGE hit from 12.2.1 -> 12.3. It's not just Geekbench that suffers, the entire system lags, has graphical artifacts, and slows down to the point where I reinstalled 11.6 on a separate hard drive and have been using that since updating to the 12.3 betas.'

same here, score of GeekBench 5 of 6900XT is low, and entire system lags, also has graphical artifacts

I wonder if the 12.2 kexts can be swapped with any success

I guess we're not the only ones.

There's the beginning of a solution here.

Hi @macmaxxx

The spoof is needed for the Radeon 6900 XTXH cards. Do you have an XT or an XTXH? An XT should work out of the box.

This is a list of XTXH cards:

ASRock 6900xt OC Formula
MSI 6900xt Gaming Z Trio
PowerColor 6900xt Red Devil Ultimate
TOXIC AMD Radeon RX 6900 XT Air Cooled
XFX SPEEDSTER MERC319 AMD Radeon RX 6900XT LIMITED BLACK
SAPPHIRE TOXIC AMD Radeon RX 6900 XT Extreme Edition

Aorus 6900 XT XTREME WATERFORCE
Asus STRIX LC RX 6900 XT TOP
PowerColor 6900xt Liquid Devil
Sapphire Toxic 6900xt Gaming OC Limited Edition
XFX Speedster Zero

If you have an XTXH card, then I need the output from your Hackintool PCI profile, and the output from IORegistryExplorer (search for GFX0). See @6rollo6 's posts here:

Hackintool output: https://www.tonymacx86.com/threads/success-radeon-rx-6800-xt-big-sur.306736/post-2311170

IORegistryExplorer output: https://www.tonymacx86.com/threads/success-radeon-rx-6800-xt-big-sur.306736/post-2311496

Hi Ted.
My new system: I9 12900k, GA Z690 Aorus Elite ddr4, MSI 6900xt Gaming Z Trio (XTXH) and Big Sur 10.6.5 .
Let me know if you need anything else.
Thanks.
