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

If you're experiencing this error message it doesn't mean your game is already running, the actual message itself is incorrect. It means The Sims 4 cannot access the Electronic Arts > The Sims 4 fold...

I just went to add Sims 4 Discover University Expansion Pack to my daughter's Mac Book Air.  Doing this through Origin, I went to open Sims 4 after the download was complete.  However, I get a pop-up window stating: "Unable to open.  The Sims 4 is already running.  Error code [ed35e0ea:29f00e76:00000000:18a1dd51]".

I have tried updating the game and repairing the game.  I have deleted and reinstalled Origin.  I deleted and reinstalled Sims 4.  Nothing worked.

I am not computer savvy, and do not know where to go from here.

I have seen this same issue come up in years past.  Can anyone walk me through on what to do to fix this for my daughter?

Thank you.
