SC2 suddenly not working

Any other Mac-users had trouble the lately? I’ve run the game for years no problem and suddenly last week it crashed on startup (unexpected fatal error, no error code).
Nothings changed on my system. Did scan/repair, reinstall, deleted virus scanners and everything else I found online to no avail. SC2 support is like screaming into the void.

Is this it for me and SC2? D-:
