The issue you're having is most probably related to your Mac's Intel graphics not being supported - http://answers.ea.com/t5/The-Sims-Mac/CURRENT-ISSUE-The-Sims-3-Issues-playing-on-newer-post-2013-Macs/m-p/4935394#U4935394
Thanks for all the information. I looked at all of that to attempt the workaround and it worked fine for about 15 minutes up until I got that "exception raised" error in the middle of CAS and it quits no matter what option I select. I understand my Mac doesn't really support the game and I wish I knew that before I bought it--it's literally all advertised as working fine. This whole issue with graphics cards isn't common knowledge unless you dig deep--which doesn't happen until someone runs into a problem. Any word on when the error will be fixed? Seems like it's been going on for over a year and doesn't seem likely that it will be especially since EA is investing everything in Sims 4.
No Intel graphics in Macs shipped since 2013 are supported so it's been 3 years now.
I absolutely agree that something should be stated in Origin about it not being compatible with Intel Iris graphics..........
