Hello! :)
Thank you for your comment!
Unfortunately we do not own a Mac ourselves and had to make the OS version on a friend's Mac so we are not sure which OS versions are compatible with it. Right now, we are unable to make other versions unless we find someone else who has a different Mac. :(
We're very sorry about that!!
There's always the gameplay video on Youtube (with no commentary) if that is all right with you, or we were told that the emulated windows version should work.
