Fails following Launcher

My son and I have played both Trine and Trine 2, and he was very excited to see Trine 3 (and eager to spend the Christmas money burning a hole in his pocket) unfortunately he is unable to play the game as it crashes after clicking “Start Trine 3” on the Launcher window. He has a 27-inch, Late 2009 iMac with 16GB of Memory.

We’ve tried reconfiguring the screen resolution, refresh rate, anti-aliasing, vertical sync and the graphic details with success. We’ve even uninstalled and reinstalled the game. I’d really like to give the game higher ratings, but it would require being able to play the game.

Ok, readling a little closer (and after downloading OpenGL Extensions Viewer) I realize that my son’s mac does not support OpenGL 4.1. Ok, it’s not like that information is pasted on the About dialog and easy to find. Fortunately, We have other Mac’s at our house that do meet the requirements. Still a little disappointing.
