Game keeps freezing randomly

[Caterpepi]

Hey, Rageworks! After the 10.15.4 update, we’re seeing some issues with the game freezing instead of the crashing reports we were seeing for previous builds. We’re gathering reports at this moment on this thread. As for the the CMD + TAB issue, this is listed on our Known Mac Technical Support Issues list.

Known Mac Technical Support Issues

Black Screen after using CMD+TAB This is currently a known issue. Using windowed mode will work around the issue in the mean time. In the Blizzard App game settings menu (Options > Game Settings), check the Additional command line arguments and enter in: -DisplayMode=0 If this does occur and the screen is black, restarting the mac isn’t necessary, press CMD+M to set it to windowed mode and bring the Heroes of the Storm client back.
