KNOWN ISSUE IN VERSION 1.0 - Crash on launch when using multiple displays
If you use multiple displays and have changed your primary display or unplugged a display since the last time you played Tomb Raider: Underworld, the game may crash when you attempt to launch it.
To prevent the game from crashing, you should delete the Preferences Data file for Tomb Raider: Underworld. To do so, follow these steps:
If Tomb Raider: Underworld is not already running, double-click on the Tomb Raider: Underworld application icon. By default this is to be found in the Applications folder on your computer's hard drive.
The Tomb Raider: Underworld pre-game Options window will appear. Click on the Advanced tab.
Click on the Open Preferences Folder button.
The preferences folder for Tomb Raider: Underworld will open in the Finder. Drag the Preferences Data file to the Trash to delete it.
You should now be able to launch the game normally.
We are working to fix this issue in the next update to the game.
