I noticed a few users mention wanting to try this. Here are instructions:
More details from Apple here. Let us know if this works for anyone else.
I’ve gotten so many crashes out of SC2 on Catalina with a Radeon RX580 egpu on a MBP 15" 2017 that it’s not even funny.
I stopped saving the Report IDs but here’s a few:
52CB4BAE-7E0A-4012-BE03-F13981BB97C4
13C767BD-293C-415F-B7EB-C589FBA638DC
2757F146-B1FD-4943-A602-3C0EB21DC372
Will SC2 become playable at some point in the near future?
LE: here’s a very fresh one B7AC9AB5-3102-42A0-82D8-EEA660BE1180
LE2: 2B171FA4-B8C8-4F57-850A-AC4203B01CF3
Same problem here. I fixed it by loading the game - and at login I cancel it (so it doesn’t try to go into the main entry screen)
I can then go to options and switch from Metal to Open GL
Now the game works but its very laggy and graphics are not good. Even at Ultra.
I’m using a 2019 Macbook Pro with an external eGPU (AMD RX570)
Hey there Nexus,
I noticed that all of the crashes reference the AMD drivers. Since you mentioned using an egpu I did want to ask if it was possible to test on the internal gpu instead?
Let us know.
Hi Kaldraydis,
Thank you for looking into those Report IDs. When using the built-in discrete GPU (a Radeon 560), the game no longer crashes (at least it didn’t crash at the points where it used to crash on the 580). Game becomes playable but performance is lacking, as expected… Switching to OpenGL while using the eGPU 580 also isn’t a solution, the game gets very laggy…
I realize there’s three large corporations that need to align here, and that it takes time, but in the meantime us users have to put up with a less than ideal experience.
Is there any timeframe we should be aware of?
Thanks again!
Thanks for the update, Nexus! No time frame on this at the moment. Our team is communicating with Apple on this matter and we are awaiting for driver updates that should come with the Software Updates, for testing purposes and a resolution.
The magic “changing computer name” method worked for me to make the game run successfully. However, the game is quite slow and have rendering problems. For example the mission intro guy’s background ‘mist’ is completed out of the confining box in the co-op mission “void launch”. My os is Catalina 10.15.2, and my laptop is the macbook pro 16’ with radeon 5500m. Please fix, thanks!
The 10.15.3 update released today. Has anyone tried the 10.15.3 update? Are there any improvements after updating to 10.15.3?
Just updated and tried it. Crashes like the Hindenburg. No changes.
So the driver/API issue (kernel panic) is still not fixed in 10.15.3? Or is it a different kind of crash?
Yes. Kernal Panic still happening after recent Catalina update (10.15.3). The game is completely unplayable and hard crashes comp to the point of restart.
Please get a fix guys. The game hasn’t been playable in Months…
I literally cant play the game at this point with the Kernal Panic crashing just after starting the game up in the menu.
Sigh… So it looks like we’re waiting for 10.15.4 now.
I had kernel panics before when using Metal on Catalina (though not every game) and had switched to the OpenGL 4 beta to avoid these. I have now played one co-op game after updating macos to 10.15.3 and had no trouble.
I will add another reply here if I get a kernel panic or after having played somewhere between half a dozen to a dozen matches without incident. Unfortunately I am a bit encumbered with work at the moment and it will likely be a few days.
Thank you all for your continued reports! It’s a frustrating issue with this going on for some time, but your patience and understanding is immensely appreciated 
I’ve gone ahead and reported this to our team in hopes for an update on this situation. I’ll update here when we have more information!
[Update] We have an update on this issue, our team have gone through testing and discussions with Apple and AMD on this issue. This is not ideal, but this should be fixed in a future update. I will update the thread here when the release is available. Hopefully, with success with eradicating this issue completely this time around!
Excellent news! Hope the update comes soon.
Following up on the above, I’ve played about 6 co-op games without issue post update.
Did you use Metal or OpenGL? I assume the version was 4.11.4? Thanks!
Also, which version of Catalina did you run?
I can confirm crash is still occurring. Happens while playing campaign mode for me after about 3-5 minutes. Also VS mode gets realllllly choppy. Specs and kernel panic error:
