SC-II quits when playing campaigns in cinematic segments

SC II keeps quits unexpectedly when playing campaigns in cinematic segments. This is happening all the time now and cannot continue playing until resolved!

This seems that started happening since I purchased the StarCraft II®: Campaign Collection as did not have this problem before.

Any ideas on what to do or patches to install? Playing on an iMac (Retina 4K, 21.5-inch, 2017) with MacOs Catalina 15.2

Hello Wences,

What I would advise you is to start troubleshooting the issue by having a look into this article.

Tried everything there, just getting worse.

Hello Wences,

I’m sorry to read about the situation. Please make sure that the game is not running in the 32-bit mode (Catalina does not support 32-bit apps):
Blizzard app -> Settings -> Game Settings -> StarCraft 2 -> untick “Lunch 32-bit client (instead of 64-bit)” if it is enabled.

Also, reset the in-game options using the same section above:
Blizzard app -> Settings -> Game Settings -> StarCraft 2 -> Reset In-Game Options
