I accidentally deleted my Electronic Arts folder whilst clearing space, help!
So, I started up Sims 4 and all my mods were working fine, I installed some new ones and couldn't find it, no matter what I tried, so, I repaired my game with origin, to no avail, and I even uninstal...
@FurryDingo and your saved games show up ok as well?
Try doing a search on your Mac for the location of the Electronic Arts folder and provide us with a path. For example Documents > Electronic Arts > Sims 4. It has to be somewhere on your computer otherwise your old mods and your saved games wouldn't show up as well.
