(Heya, long time lurker here finally inspired to make an account due to actually paying for a game and having it not work.) I very, very rarely had apps crash when using Tiger or Leopard, but since I recently upgraded to Snow Leopard (I know, I'm so current), it's been an increasingly regular experience. The OS itself has crashed/frozen a good dozen times since upgrading a couple of months ago, as well, which easily equals the number of times the same thing happened with previous OSes in the five years I had it pre-SL. Overall, Snow Leopard has been a pretty disheartening experience. Especially since I can't play Diablo! Just finished installing D2 and it immediately crashes every time upon launch. Model A1211 MBP. The crash report is attached as a txt file; hopefully someone here can diagnose the issue.
