macOS 12.3 Update Causes Problems for 5700/6800/6900 Graphics Cards

[tedyun]

I've been literally waiting for an official update before purchasing a 6900XT (6800XT would make more sense considering the MSRP difference, but in actuality they are pretty much the same price). Any brand recommendations?

I think they are all basically the same. Sapphire and PowerColor are solid. I also give ASRock a thumbs up! My Vega 56 was basically plug and play, no problems.

If you have a dual boot system, you might want to think about the 6900 XTXH cards. If you game or like to tinker, you can really push these cards to the limit. The downside however, is that out of the box, the macOS doesn't support it, so it requires some additional work to spoof the drivers (you basically trick the macOS to think that the XTXH card is a regular XT card), and the benefits of the XTXH are not fully realized on the macOS side.

Edit -- I see that you have a X299 system. The XTXH spoof is a bit more complicated for these systems, so if you don't want to bother getting into the weeds with it, I would just get a regular XT card.

Does this help with fan curves and keeping idle temps down?


(kinda feels like the might be specific to us here with Hacks and not a macOS/Apple thing)

Confirm! 12.3.1 fixed the issue. Although with RX 6800 XT spoofed to AMD Radeon PRO W6800X I have better benchmark.

Where did you guys get this update? My system update panel doesn't show any 12.3.1 at all... Hmmmm...???

I think it's important to note that the spoof was breaking power management and fan profiles, as such card was staying revved up. that always boosts benchmarks because of the inherent flawed way geek bench works.

because it literally pauses between each test, the card goes back into an idle state before each test, which means the start of each test the card first has to rev up. this drops score conciderably. when card is broken or rather when power management is, the card has the appearance of performing better because it starts each test from the revved position and not idle one.

I have said this countless times but geekbench is actually a really bad benchmark tool because of this fact.

With injection i was getting 180k, without it I only get like 150-160k, but when I actually put the card on a real load, the fps is same between injection and injection-less. The difference is working power management. I'd wager that if you injected something to kill only the power management you'd get your peak geekbench scores.

I confirm 12.3.1 is working like 12.2.1

How are you guys updating this? My software update does not see any 12.3.1 at all.

If you are enrolled to BETA, first unenroll: "sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil unenroll". After update enroll again if you wish: "sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil enroll DeveloperSeed".

How do I know if I am enrolled in BETA? I don't remember signing up for it at all.

Thanks for the response.

I went ahead and unenrolled and it said I wasn't enrolled so I guess that's that...
