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

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.

@milidarriulat I created a new user account on Origin. The Sims game is connected to my original user account. Is there a way to allow the new user account to use the game on the original user account?

Thank you for the help.

I'm having the same issue - created a new user on my Mac to get around the problem, worked for one day, now I'm getting "Unable to start: Origin is currently not running. Please make sure that Origin is running before attempting to play The Sims™ 4 [d3382ced:984c6a38:00000001:00000000]".

You have both posted a different error message stating that Origin is NOT running. Can you please confirm whether this is the actual message you are receiving?
