You have to go to the app store, under utilities.

:( I am trying to play on a 2009 Mac mini. The Island Rum launcher comes up, but when I hit play, the green checkmark shows for about 10 seconds and goes away. I've tried deleting and redownloading, the rescan option, all the steps in the initial troubleshooting guide. The strange thing is, my son also plays on a Macbook (which I set up for him) and his works fine. PLEASE help. I did play on this same Mac before the game closed.
