I just downloaded SMB from the Humble Indie Bundle V, and have been experiencing immediate crashes as soon as I start up the game. Ive tried using the Steam version, but experience the same crashing.

I looked through the system requirements, and meet them just fine, but cant seem to start up the game. I have a 1yo macbook pro, 10.8.6 with 4 quad processors, so that should be fine. Does anyone else know how to solve this problem? I mainly got the bundle for this game, and now I can't even play it
