Re: SIMS 3 NOT LAUNCHING - MAC

@anivazqueza  Please move the Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just see whether you can get far enough to start a new save.

If you have the same issue, run the Origin reset tool:

and repair the game: open your Origin game library, right-click on the Sims 3 icon, and select Repair.

If that doesn't help either, please let me know whether you use iCloud, and if so, how full your cloud storage is.
