SC2 crashes on Mac 10.15 Catalina

I also can’t find the 32bit setting in the menu - I only have “additional command line…”, text and spoken language and “Reset In-Game Options”.
My Starcraft2 permanently crashes during the same cutscene - I can’t play the game anymore. Sometimes it even reboots my back.

If the 32-bit option is not showing up for you it means you are set to use the 64-bit automatically so that is fine.

This issue seems to be caused by a known problem that started months ago, 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.

If you have time follow the US forum thread here there are few other troubleshooting steps you can try, but if nothing works I’m afraid you will need to be patient for now.

Hi just updated to Catalina today and now I can’t even open the game client and the computer is telling me to contact the developer. When can we expect an update so I can even open the game?

I updated to 10.15.3 but SCII still crashes (freeze + restart).

Same here. Looking forward to getting this solved ASAP :weary:

I have a very old MacBookPro, Mid2012. Since some OS updates SCII started crashing right away, unable to boot.
I updated several times with all the fixes created…
I lost hope and thought that maybe my Mac is too old (But Catalina is supported).
But then… I read above this:
If the issue persists there is a workaround that apparently helped other players which is to rename your system on Mac:

  1. On Mac Apple menu, go to System Preferences/Sharing
  2. Change the Computer Name to something different.
  3. Click on Edit and then Okay.
  4. Close the Preferences window.
  5. Test the game again.
    It is really strange this bug, but I changed my computer name in sharing and now boots fine! I am soooo happy!

For anyone who hasn’t tried it, this worked for me.

Switch to OpenGL - In SC2, go to Options (Press ESC) > Graphics (Default tab) and change the Render API to Open GL 4.1 (Beta)


This did work for me as well, but so many of the storyline mini-cinematics (like the character faces when you select a unit or in the cantina in Wings of Liberty) have little to no detail. Did you or anyone else experience this? It’s not like that when I use the Metal API (before it crashes of course).

Tried this idea too (after months of no use) and it worked. Thanks Zarinde!

I have the same issue. Freezes the whole machine so I have to hard reset. The game freezes on Campaign play. Not freezes on ladder games :man_shrugging:

Way to go Blizzard. Finally an update and you still haven’t manage to fix the problem!!! I cannot play the game, because it always crashes during the same cinematic scene!!!

Hi this has been reported for months now, how long is it going to take until we can play a game that we’ve paid for? You should be testing the Mac OS releases while they’re in Beta so you don’t have these issues when Apple release new software…

Hi I can confirm changing the computer name has allowed me to start the game. What a bizarre bug?

I still have the problem. campaign or coop crashes the game. Ladder no problems !!!

I have no problem with any other game. Warcraft3 Reforged and WoW runs for hours.

Catalina 15.3. Blizzard Please fix this Bug :frowning:

Mac OS version:

Hey all. I am running macOs Catalina 10.15.3. My current issue is that I cannot even UNZIP or I receive the error:

The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.

Or the Error:

Unable to expand “ It is an unsupported format.”

I have tried other unzipping apps like Unarchiver and receive the same error so it has nothing to do with my Mac’s ability to unzip. Thoughts? I’d rather NOT downgrade my version.

I have the same problem with 10.15.3.

It happens during the campaign, in the following cinematics:
After beating the first level of the wings of liberty campaign (the moment Thyfus comes in). If I restart the game I can actually watch the cinematic.

Clicking on the Kerrigan photo on the board shuts down my computer instantly with a panic.

The cinematic after beating level 3 also nukes my computer. The game runs fine during gameplay, it’s only during the cinematics.

This is my hardware:
Macbook Pro 15"
2,6 GHz 6-Core Intel Core i7
16 GB 2400 MHz DDR4
Radeon Pro 560X 4 GB
Intel UHD Graphics 630 1536 MB

The workaround I read above works for me too:
Switch to OpenGL - In SC2, go to Options (Press ESC) > Graphics (Default tab) and change the Render API to Open GL 4.1 (Beta)

It comes with the price of blurry faces, but otherwise I’m happy I can at least play for now.

Same here, panic immediately after click Versus. Co-Op works fine.

Same here, MacBook Pro 2016. Everything was running fine yesterday on Mojave. Crashes sometimes immediately, sometimes after a couple of seconds of multiplayer game.

Same experience. I have a maxed out iMac Pro. The game played beautifully on Mojave. Game freezes the entire system on Catalina. Such a bummer.

Same issue here when running 2017 MBP on 10.15.4
