I reinstalled all of my games through Origin after my Mac kept crashing with the external discs. I got the patch and everything. It was a seemingly flawless transition and fix, and I was even able to play for a couple days. Suddenly, I could only play for about 5 minutes before the game would exit itself and tell me that there was an issue, and I could choose to debug it. I kept allowing the debug, but it never actually fixed it, it only quit the game and gave me the same problem the next time I tried to play. I even tried ignoring it, and it still quit the game. At this point, I am pretty convinced that I am just not meant to play this game because I can't seem to get it to work no matter what I try and what I reinstall. Someone please please help!
It's most probably memory related, your game is hitting the 2Gb maximum it can use. You need to purge RAM frequently during gameplay and save often. Give that a try and see how you get on.
