mm, generally speaking, it should just run from the exe after extracting the folder.
Does it produce an error when you try using it?
I sadly don’t own a mac, so I can’t test it :(
All it says is that it can't be opened, with no other information or messages. :(
I install RAR extracter should be normal in the store and then install JoiPlay in the internet.
When you extract the file you can go in JoiPlay add the game go on the game and below should be stand game.exe click on that and you can play.
