AEROSPEED  While I love the fact that the Halo 2.0.3 update makes it so I no longer have to use my CD to play, now my MacBook Pro 17" gets little blinking squares all over the graphics when I try to play the game. A friend with the same computer (but one rev later) has the same problem with the update. Neither of us had the problem prior to installing the update. Haven't had a chance to try it on a PowerPC machine yet.
