@kace12345 I've tried everything they suggest in here: updating my mac software, resetting my NVRAM, repairing my game, and also enabling vertical sync and disabling retina display. To be honest, my game was running perfectly before I decided to go to this specific lot (Chic Street in San Myshuno). I don't really understand why only this lot has an issue, or why could that even happen, but if you checked this thread a lot of users have issues with San Myshuno, have you tried playing in another world? It still pisses me off, and apparently this has been going on for quite a while and EA has made no comment on it but I am able to play avoiding that lot in the meantime.
I suggest you to try fixing the game, updating your MacBook software, resetting your NVRAM, checking your icloud driver, enabling Vertical sync, and also: I do find that playing full screen rather than window does help (It's a lot, but I tried everything so I don't know for sure what action helped the issue). Graphics my still be weird but it's a lot better imo.
Hope it helps!
