After I upgraded the D2X menu comes up black. itunes still starts and you can get the game to actually play if you click your mouse on the right part of the black screen, It was working great before I updated. I tunes acts a little funny sometimes repeats the same track and the volume gets turned way down. If you go to sound and play with the music slider you can get the volume back up. Hope this gets fixed because it's grea tto play the game and my joystick works like a charm. Logitec's extreme pro 3d.
I booted off another internal drive that still has 10.4.2 and the same game install runs fine so it definitly has something to do with 10.3.4
