Are you using Store Content in your game ? There seems to be an issue on Macs where certain Store Content conflicts with the disc authentification.
To make sure that is your problem, move the folder DCCache in documents\electronicarts\thesims3 to the desktop (this will rid you of all Store & Custom content so start a new game for testing purposes). If the game then starts, you need to find out which stuff is causing the conflict. To do so, first put back all files that have the ending *.dbc (those are third party content so you may not have any). Start the game and see if it still works.
If it does, start reinstalling the Store content. I would start with any premium content you might have. If it still works, go on installing the rest, in groups until you find the guilty party.

If you do, PLEASE let us know what you found. Many have this issue and it would be instering to know WHAT is causing this conflict.
