[2023] EU4 won't launch on Mac(downloaded from Epic store)

This may be a bug in the launcher, which seems to require MacOS 12 now. Were you at all thinking of updating MacOS? If so please do that and confirm for me that it helps, then I can report that to the developers.

There's a newer installer:

But I think the problem is in the launcher itself, not the installer.

FYI there are WIndows and Linux ones too:
