Re: Can't run sims 3 after uninstalling expansion packs

@iiRaSims  Please uninstall Sims 3 using this guide:

Reinstall the base game only, if that's what you want.  Then run the Super Patch (digital download version) to manually patch to 1.67:

Please also go into Documents > Electronic Arts and move the Sims 3 folder to the desktop before trying to play.  Let me know whether the game works after that.

And yes, you must be playing the 32-bit version of Sims 3 because your Mac doesn't support Metal and therefore can't run the 64-bit version.
