it's saying another application is being used, I uninstalled sims 4 and origin and got origin back but I can't get into because it's telling me "someone else is using it" it's been doing this for at least a week or two. I saw somewhere that I needed to open OriginClient but that was removed too. help !

@nbandsss Please do a clean uninstall of Origin:

Restart your computer, reinstall Origin, and see whether you still get the error.

So, I saw somewhere to go the activity monitor and look for OriginClient and this tends to stop the problem, but doing both definitely helped. Thanks!!!
