Hi
You should reallly patch before installing custom content. I would recommend that you first pull your The Sims 3 folder from inside the Electronic Arts folder in Documents on your Mac and move it to the desktop. This will instantly uninstall your CC. Start the game so that a fresh folder is generated. Now use the superpatch (see below). Once you are patched, test that you can play the game. If it seems OK, start adding back your CC (you don't have to redownload it - just take it from the old folder still on your desktop and transfer it into the new folder that was generated).
Manual superpatch
Many simmers find that patching their game via the Game Updates tab of the Launcher does not work properly. It is then better to download and apply the manual superpatch. It is important to download the Mac version rather than the PC version, and to pick the right one for your region. Be aware that if you are using a disc you need to choose the correct 'regional' file but if you are using digital download through Origin then you should use the file designated 'region 7'.
Instructions and the links to the downloads can be found in the Mac section of the forums at thesims3.com here:

If you use any mods or custom content, be sure to remove them before patching.
