Thank you for the feedback.
Can you give me some more information about what exactly is not working?
What OS version are you using on your mac?
Do you get a specific error message?
Don't you get into the game at all? (No unity screen? No game menu?)
There should be a log file at this location, that might help locate the problem. Feel free to post it here, if it's not too much trouble: ~/Library/Logs/SteFunGames\Monsters of Windy Peak/Player.log
Thanks again.
