Hmm… I’ve been playing for a few weeks without Discord, in fact with nothing but Wow running. It still freezes up occasionally, but it’s only the game. It hasn’t taken the whole OS with it.
There was a suggestion that it could be related to addons. As Heigan’s room seems to trigger the issue a lot, I tried disabling addons for that encounter and the game didn’t freeze. Obviously a single data point doesn’t prove anything, but it’s something to consider.
I have read in other threads that any application on macOS that uses hardware acceleration may be causing the crashes. I try running with out any other apps running accept wow and disable hardware acceleration in the Battle.net app. This may help a bit. I am hoping that big sur 11.2 will correct this issue.
Spoke too soon. It just brought the whole system down 
Any news on this?
That’s the exact Mac I run and running wow alone and disabling hardware acceleration where I could has helped a lot.
Hardware acceleration on other apps does seem to play a part. Reducing apps running it definitely reduces how frequently it happens, but it still does happen. Maybe that is from the WoW client itself having whatever issue happens from acceleration. I am still on 10.15.7 but will be taking the Big Sur plunge this week. I have a dev account and may try 11.2 but will see.
Installed Big Sur, only done one raid and some standing around org but so far so good. Fingers crossed it continues.
There was a suggestion to try a new user account. It didn’t work. By extension this means it’s not related to ‘true tone’ as I had that off in the new account.
Another suggestion was that addons might be causing the issue. I’ve now been through Heigan’s fight four times with addons disabled and haven’t had any GPU restarts, so that’s promising.
Now for the hard part: Figuring out which addon it is.
So far so good on Big Sur, I’ve only done a few raids but zero issues, so fingers crossed.
Finally had it happen again when ony buff went out in org
Presumably you’re still on OS 11.1?
Correct, haven’t bothered with 11.2 beta, not sure if I will because of some other work related things I have to support on this machine.
It’s no longer beta; it’s been released. I’ve installed it, but due to the intermittent nature of the issue it’ll probably be a while before I can say whether it’s fixed (although none of the ~15 other issues I reported have been, so I’m not holding my breath).
If my experience is any indication, the problem is not fixed – in fact, it may be worse.
Until tonight, I’d never experienced the freezing problem. I’m running a new M1 mini, but I’ve been playing for a few weeks now without a single occurrence of trouble – until tonight, after I upgraded to BS 11.2. After the upgrade, I experienced the freezing problem at least half a dozen times, including five times in Torghast.
Hoping Blizz figures this out soon.
Same issues here. Worked perfectly fine on 11.1, now 11.2 causes my screen to freeze and macOS to restart. I can hear sounds in the background, but the Mac is totally frozen until it restarts the OS. I noticed they unlocked the frame rate in 11.2, so it’s not on 30 or 60 most of the time, but the FREEZING sucks. Please work with Apple to fix this. I was so happy with 11.1 and WOW, worked flawlessly, now 11.2 drops and I’m seeing freezing issues…
Same here!
I thought my machine was just crapping out on me, both glad and sad to see the replies. I’m on an iMac Pro with the Vega 64 16GB. Now with Big Sur the issue is lockup for 10-30 seconds then resumes. Much better than before where it would just lockup completely. I wonder if we will ever see fixes on this.
I’ve also been experiencing this problem. Just read on another thread that power cycling your display fixes the problem. I’ve had three freezes in an hour tonight – power cycling fixed it every time!
I’ve been talking to Blizz and they’re aware of the problem but haven’t yet figured out what causes it. If you haven’t already, log a ticket: They want to know which CPU/GPU/OS combinations have the issue, and the more information they have, the better.
Edit: I misread the GM’s request. Please put your configuration in this thread and I’ll send a link to Blizz.
Yeah been having this problem intermittently across two different machines since I switched to macOS full time. My 2018 Mac Mini + eGPU got the issue a lot more frequently, but my 2019 Mac Pro still has the problem. I also get this on FFXIV, so it’s not exclusive to WoW for me. But it’s only when playing games, not any other time.
