sims 3 Mac error

★★ Novice

hello everyone, I just bought the sims 3 for my Mac book and when I first installed the sims 3 I was able to open and play the game. a few minutes later I installed both late night and high end loft packs and it gave me an unknown error message. I quickly uninstalled all of the games and just reinstalled the base game but I still the message not matter what I do? 


now Im super lost since im not great with computers but Ive followed so many tutorials to fix this but none work.

Re: sims 3 Mac error

@rhiannnonn  The fact that you were initially able to play the base game without issue is a good sign—it means you can probably skip the most difficult step to fixing the unknown error.  But when you uninstalled TS3, the uninstaller probably missed some files, which is why you can't launch the game now.  So the first thing to do is manually uninstall everything.


Then reinstall the base game only, and patch to 1.67 using the Super Patch (digital download version).  Even if the game thinks it's already patched, it may not be, and the Super Patch can't hurt.


If the base game runs now, you can install HELS and LN.  The reason that the game wouldn't launch after you installed the packs the first time around is that LN didn't have its own alias in your Applications folder, alongside the alias for the base game.  But creating one is easy:


Please note that if you ever install any other packs, you'll need to use another workaround as well.  (Luckily, there's a video guide for that, if you need it.)  If you still can't get the game to launch, or you run into any other problems, please post your specs here, along with any error messages you're seeing.

I don't work for EA. I'm just trying to help fellow players with their games.
