The attached image shows some of the distortions.

It doesn't go away and says around throughout the whole gameplay. 

I noticed it occurring the other day after I was clearing some cache on my laptop, although I'm sure that I didn't clear information from the sims game file. Anyway, I have tried to repair the game, to update it, I even uninstall the game and packs, and reinstalled the game.

Also, it is worth mentioning that I use a MacBook Pro, and it runs perfectly otherwise. I have run Sims 4 for many years, as well as other programs on my laptop and have never run into this problem. I have no clue why this might be happening, I am not sure what else to try. I have also tried adjusting the graphics settings within the game to the lowest res and it still occurs. 

if somebody could help me out I would greatly appreciate it.

Thanks.
