I have two monitors attached to my computer. How do I change which screen the game runs on?
If you have more than one monitor capable of supporting the game connected to your Mac, you can choose which one to use from the pre-game Options window.
To do this, follow the steps below:
Double-click on the application icon while holding the Command (⌘) key down. The pre-game Options window will appear.
Select the Displays tab in order to choose a monitor.
Holding down the Command (⌘) key while starting the game will also display the pre-game Options window.
NOTE: If you have two monitors connected to your Mac, you may experience a drop in performance.
