Sims 4 Button Greyed Out After Update (MAC)

I opened Origin this morning and it started to automatically update my game. After it was done, I went to press play but realised it was greyed out. I completely closed Origin, then tried again... still greyed out.

I've looked through these answers, and everything is about clearing the cache for Windows - does someone know how to fix this problem for Mac? Also, is there a way to fix this without losing all of my saved data/gameplay?
