I just got a 400 g3 for my daughter for xmas to update her 333. System 10.2.8 installed and updated with no trouble, 768 ram, 12 gig dvd drive. I know Garage Band (Ilife 04 version) isn't supposed to work on a 400 but most people are able to get it up and running at least for basic features. I tried installing it several times but it won't open at all. Acts like it's going to open. Bounces a few times and "Garage Band" shows up at the top in place of "finder" for a few seconds. But then it stops. Puter doesn't crash or anything. It just stops trying to open Garage Band. Anyone have any suggestions? I tried repairing permissions and that didn't help. All else is running great in os x on this computer. I am stumped. Any help would be hugely appreciated. Garage Band is all she wanted for Xmas and the 400 was all I could afford this year.
