Hi All, Macbook Pro 15 2.2 with the 1GB graphics card arrived earlier this week. I decided to buy Trine from the app store - all went well until I decided to quit the game. The game returned me to the desktop but I couldn't shut down the mac or select anything - the icon bar at the bottom of the screen had vanished. I could move the mouse pointer but not select anything. Anyway, tried keyboard shortcuts to find a similar function to Windows CTRL+ALT+DELETE but nothing worked. I had to hold the power button down. Anybody know if there is a better option to sort the crash out rather than just the power button? Thanks, Rob. PS - the graphics card sounds like an aircraft taking off when it kicks in - v. loud!
