So i did something on accident that may have fixed my issue. First of all I got sims 3 to load in another account on my mac. I went into Settings and clicked on my picture and added a new user. Then I went into that account, (a million set up questions, skip on linking Siri, etc) I downloaded the EA app, logged into it with my user name and password and launched Sims 3. It loaded up - so I knew it would work it was a settings issue. I tried to repair it from this account. then i closed this account and went back to my primary account.
In my primary account it still would not load. Then I took my downloads folder from my main Documents/ EA games/ Sims 3 and i put the documents on the desktop. And then I restarted sims 3. and it runs. the game will create a new Downloads folder when it launches. I added my downloads back into that folder. This glitch has something to do with a file in the downloads folder I'm sure.
