I haven't found a thread that talked about this yet, but when I play EU4 on my M1 Max MacBook Pro 16 inch, the Mac enters lockdown mode (as in it does not allow me to leave the game). I basically had to abandon EU4 simply because I can't be locked out of my Mac when playing. Sometimes when I want to leave, it also crashes so I need to turn off my Mac to leave the game. I really hope there is a solution for this. I play on fullscreen 2560X1600, which is the only version that works at all (and I tried all other options). And to people who might call out the fact that I play on Mac, I use it primarily for other things, so if this doesn't work out it's just a minor inconvenience.
