That's fine, lol mac is always annoying to deal with
You should be able to get the linux version to work on Mac in most cases, assuming the dependencies are available (similarly, if you ever see a renpy game that says windows-only on here, grab it anyway, renpy is platform-agnostic, it'll run on windows, mac, and linux just fine).
Can't speak to this game specifically, just browsing around and saw your query.
