Unable to start: Initialization error at start up.

Hi, 

I have the Sims 4 Legacy on a Mac 10.9.5. Having no mods installed at the moment, I cannot launch the game. It worked perfectly yesterday. 

Error message: "nable to start: Initialization error at start up. [135dec40:90f690cf:00000075:495f32a0]".

I have tried the following:

- repair the game
- delete origin and installing it again
- reinstalling the game
- change language in origin.

Nothing works - please help! I love sims but all these problems are ruining my gaming experience... Not the first time I run into problems.........
