Recently I had a new hard drive put into my Mac and I reinstalled Sims 3 and all of my expansion packs. Every time I tried to play it said that an unknown error occurred so I completely uninstalled sims and origin from my MacBook then I reinstalled ONLY the sims 3 base game, which ran fine. I closed that and installed the ambitions expansion pack but when I attempted to run the game, the 'unknown error occurred' message popped up again! I really don't know what I should do now! Any ideas??

Hi, I had the same problem. The first time I tried this it didn't work. I decide to reexamine my game files and I found that it wasn't just the files for Ambitions and Late Night that were missing, it was also Outdoor Living Stuff. So I recommend you check that ALL the expansions/stuff packs you bought are present, not just ambitions/late night.

I'd just like to shout THANK YOU a thousand times. This and @corey_0414 saved my life after I've frustratingly been trying to manually uninstall and reinstall these add-ons, the base game, and Origin client to no avail.
However, just to help people with the installation process, I'd like to point out that I had the same unknown error issue after trying to install Outdoor Living SP. This is fixed with the same solution as copying/pasting the Late Night/Ambition folders into the right places. I'm not sure if other people experience this as well but I just wanted to let you know. Thanks for the help guys!
