Re: Repaired and reinstalled corrupted Sims 4 file, but it's still corrupted

I'm not a Mac user, so if this doesn't work, you may want to post about your issue on the Mac Board: https://answers.ea.com/t5/The-Sims-Mac/bd-p/The-Sims-Mac

It sounds like you may have some outdated mods/cc. If that's the case you might try taking your Mods folder out from the Documents\Electronic Arts\The Sims 4 and move them to the desktop or some where else safe, and try the game again.

Delete the localthumbcache.package from the Sims 4 folder. This helps clear up some game glitches and will help to make sure there isn't any issues with any mods or cc. Like mods/cc that are outdated or no longer in game.

If the game runs well without the mods folder. This most likely means that it is outdated mod or cc. This can happen as we get updates for the games, some mods and custom content become outdated. You'll need to to go through your mods folder to find what needs to be replaced.
