Star Wars: Knights of the Old Republic "quit unexpectedly"
So I was happily playing Star Wars: Knights of the Old Republic on my Macbook Pro running OS X Yosemite, and all of a sudden the game crashed. The first time this happened, I was transitioning between cut-scenes and the game crashed, bringing me back to my desktop. Then a window popped up and said that the game "quit unexpectedly" and asked if I would like to report to Apple. I said no and rebooted the game. I arrived at the same point again after loading my save game and it crashed at exactly the same spot. I am hoping that this does not mean that my copy of the game is defective, because it would be a shame not to finish it! I downloaded the game from the App Store a few months ago, and have had no crashing issues until today. Wondering if anyone might have any suggestions to fix this...I'm not really a computer wiz and do most of my gaming on consoles, so any help would be appreciated.
MacBook Pro, OS X Yosemite (10.10.1)
