macOS Sierra 10.12
Issue:
The game will not load or the Unknown Error message is popping up since updating to Sierra 10.12
Try:
I have Sims 3 as well as the late night and generations expansion packs and custom content. I've had these for several months but now my game has started acting weird. It would get to the page where you pick your family and it would say "Disc Authorization Failure, contact customer service". I read a few forums and they recommended uninstalling the games and reinstalling them using origin. So I did as instructed and now the game won't even load and it'll say "an unknown error has occurred". I've tried everything, restarting my computer, checking for viruses, deleting my custom content, etc. Nothing works! I've had my friend log into my origin account and it works on her computer but not mine...
Here is some info about my MacBook:
It's a MacBook Pro (mid 2012)
it's running on macOS Sierra (Version 10.12.1)
Processor: 2.3 GHz Intel Core i7
Memory: 4 GB 1600 MHz

I only have Sims 3, Late Night, and the Loft stuff expansion, however I currently only have the original sims 3 installed. When i got to open the game, it says unknown error occurred. This problem only started after the installation of macOS Sierra.
