I hope this is related because I am frustrated trying to fix it. I installed the patch after dragging the sims folder to the desktop, then installed IP. When I launched the launcher to install my store content, it asked to install a store patch, which I did. I reinstalled all my store content (no tmp files appeared), closed the launcher, put back in any files from my previous game and relaunched. All store content says it's installed via the launcher, but in game, it doesn't show up. I still have no tmp files.
Size of Dccache: 603.1 MB store content only, no Custom content, no tmp files.
I'd love to go around the launcher, but it seems very complicated on a mac.....
