[MAC] Sims 4 Launching Problems [ Edited ]

[camilaxoxo]

Alright so here is my problem. I have been playing smoothly on the sims for with my MAC for almost 2 months now. Today I wanted to play it for fun and it wouldn't launch 

It said 

Unable to start:

Cannot start because required game data is missing or damaged. Please try reinstalling the game. 

I uninstalled and reinstalled. Nothing. I never touched or damaged SIMS 4. In fact, the day before this happened It worked as smoothly as ever.

Again, I have a MAC and I had it for 2 months and played it everyday. I tried to Repair game through origin and I didn't do anything to the sims4 file. HELP!

Hi @camilaxoxo,

Are you using mods or custom content in your game?
