I'm sorry it has issues, I haven't been able to test it since I don't have a mac. It should have been the same as the windows version. I'd be interested to know if anyone else experienced this problem too :)
first of all you need to drag your download to the applications folder. After that you need to open the terminal on your Mac. From there enter this line of code "cd /Applications". Then enter "chmod -R 755 Game.app" into the terminal. That should do it.
