I made a fully-fledged YouTube tutorial for installing this game for M1 Chip and Intel Chip Macs.
Why the app doesn't launch?
- The reason the app does not launch is because the executable inside the .app file does not have execution permissions.
- The second reason is because the .app is made by an untrusted developer.
In this video there is all of the steps in this comment section combined. I also run this on latest macOS and M1 Mac mini so you don't have to worry about compatibility issues, also because it's running through rosetta so it works for intel too.
