@SheriGRThat’s exactly what I would have expected. As I explained in my previous post, moving out the old folder forces the game to create a new, clean one. As well as creating the new folders I referenced it also resets graphics options and clears out cache files and screenshots (they will all safely be in the folder you moved out). The Sims 4 stickied thread on the first page of this Mac forum is full of information which you may find helpful and informative -
