I repaired my game, I created a new Sims 4 folder like you suggested, and then “Unrecognized Video Card” popped up when I loaded up the game (attached). Should my graphics be set up a certain way on my Mac? I also did this as suggested in another related thread:
Origin in System Preferences/Settings > Privacy & Security > Full Disk Access?
Now I loaded the game again and it just froze on the loading screen in between swiping between the words and the plumbob had disappeared, so essentially after creating a new Sims 4 folder, the game won’t load.
