Just curious, what kind of Mac system is necessary to avoid constant glitching, etc. with the expansions.
For reference, I'm on Snow Leopard 10.6.8 with 4GB of Ram and a 2.66 GHz Intel Core 2 Duo processor. For the longest time I was running the game with Generations, Late Night, Ambitions, and World Adventures with zero problems. I mean, I could play for ridiculous amounts of time without having to worry about saving.
When I installed Showtime, that seemed to be fine, but it was around the time that I got Seasons and Pets that things started going wonky. However, this was also around the time that I discovered the store. I went ahead and grabbed supernatural too, which hasn't worsened the issue, but it is a pretty shocking difference from a few months ago to now, where I have to save around twice per Sim day, and after two Sim days, generally get an Error 12 or a freeze/crash.
I clear out all of my caches and superfluous files after every game.
I moved my Legacy family to a new town to see if that helped matters, installed Overwatch and ErrorTrap, and disabled memories, but still no dice. Anyway - any insight at all would be welcome.
