Ok so whenever I try to open Ts4 the little icon (sims4 game icon) pops up on my app bar thing (I use a Mac), but then it just goes away after like 2 seconds and the game doesn't open or anything... I dont have any new cc since last time I played so please help me someone!!

Right click on the game in Origin and select repair game.
If that doesn't fix it run the Origin reset tool then try again.
Make sure Origin is disabled in-game.
Please try those three suggestions and let us know how you get one
