Has anyone successfully used The Sims 3 in Mavericks? Does it work as expected or are there any special steps to take? How do you backup Expansion Packs? (I know how to backup game play data from the EA folder) I have several but I do not know where the discs are and I am afraid of losing their content when I re-install. I know an upgrade or restore would avoid these issues, but I feel like my MBP has acquired some gunk and I am considering a clean install and starting over.
