Re: [MAC] My Sims 4 isn't working!!
I have the same problem as you, but I have done my research. I got all my cc (custom content) from my mods folder and put it into a random file on my desktop. I then checked for an update and repaired the game; I was then able to open my game without any problems except all the cc wasn't in the game anymore. Once I had done this I then dragged some cc back into the mods folder then checked for an update/repaired game to see if it was any of that cc. I would then repeat this until I found the cc that was making the game crash/disabling the game to open.
this worked for me but may not work depending on the problem...
