The game had massive issues on macOS 11.
As of now: is the game working on macOS 13/Apple Sillicon?

I don't use macOS, so sadly I can't give a direct answer. Supposedly macOS Catalina (10.15) dropped some graphic support, but it could at least be resolved by adding a specific command line argument. Aside from that, I have read a case from last year on the Steam forums were a user ran it on an unspecified version of macOS. Since Rosetta (not relevant by itself) was mentioned there, it would imply the user was having version 11 or later.

So maybe it works? I've been unable to find any confirmation on this.
