Please can you try following the instructions on applying the super patch manually here. Gatekeeper is probably stopping you from installing the patch because it's not signed properly by EA (it's perfectly safe to open).
Hi there, i had to wait for my sims 3 to re download from origin after i deleted it to try something. I have tried to do the patch following that pages instructions but it still doesnt work. I think i will just partion my hard drive to Windows and Mac and try and play it on Windows.
Thanks for your help
