What do I have to do to use Flight Simulator X on my MacBook Pro (Proxessor 2.33 GHz, Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM)????? A message appears: "Flight Simulator is not working with your video card. Verify that you have the latest drivers installed installed for your video card. Flight Simulator will now exit. Could someone tell me what do I need to do?
