Unable to start: The Sims 4 is already running - Mac only

Hi, I haven't played the sims4 in about a year and tried to load it today. It is coming up with the error message that the sims is already running. I have tried everything redownloading origin, re-downloading the sims, updating my Mac and just don't know what else I can do. I have tried to find my EA folder in the documents but can't find that anywhere even after using the repair tool so now I am completely stuck. Any help will be appreciated as id love t start playing the sims again.
