This free patch takes the economy simulation Airline Tycoon DLX to Universal Binary, meaning the game will then run natively on any new Intel Mac. Please download the patch, but make sure you only use it on the game if you have an Intel Mac or MacOS 10.4.x installed on your computer.
Don't have Airline Tycoon Deluxe? Buy the digital download version from Macgamestore.com available here.
