Mac - Initialization error at startup [135dec40:a69d8f94:00000000]

So me and my brother both updated sims 4 at different times we had just downloaded mods the night before and he started the game at first and it worked but, it wouldn't let him enable his script mods so our first instinct was that the update somehow cleared the mods so he removed the mods, repaired the game and then he started the game and it said:

"Unable to start:

Initialization error at start up.

[135dec40:a69d8f94:00000069:00000000]"

so he figured it wasn't working and he probably had to install and reinstall the whole game so as he was, his hotspot is almost running out and we have no wifi at the moment, so he isn't able to redownload the whole game right now.  well I figured since I also have mods I shouldn't update but it would not let me play unless I did, so I updated it using all of my own hotspot, and it worked at first mods and all but I could not save the game and gave me an error code. so I repaired it and it gave me the same "Initialization error at start up" as when my brother updated it and I decided to restart my macbook but it still is giving me the same error. I have no clue what to do and I saw that everyone is having these same issues, all I wanna know is how to fix it, any suggestions???
