Re: Sims 3 Debug Error on Mac
Try following the steps for a factory reset to see if the game itself works. The steps for doing one on a Mac are in the link Crin posted above, but I'll go ahead and copy/paste them here too:

"- The first step to trying to figure out how to get your game working again is to try a new game, without any CC, mods, saves etc. This will help figure out if your install is dodgy or you have corrupted data. Doing this is simple, open your Documents folder then open the Electronic Arts folder. You will see one folder in there called The Sims 3. Drag this to the desktop. DO NOT DELETE IT. This folder holds all your game data like downloaded content, saves and everything precious to your game.
- Now, fire up your game (it regenerates the folder you just moved) and see if you can play with a new Sim in a new world. Make sure you open CAS and make sure you try out Build/Buy mode. Try playing for at least an hour or so. If that works then the installed game and EPs/SPs is fairly stable so the issue lies somewhere within the folder you moved out."
