You can’t use this version of the application “Divinity - Original Sin 2.app” with this version of macOS.

but you can open the "Divinity - Original Sin 2.app" by right clicking and clicking show package contents, and then running the file at this path

.../Divinity - Original Sin 2.app/Contents/MacOS"

then the game runs fine.

Larian why its marked as not compatible?
