Unknown error on my download

So I currently play sims 4 on my MacBook, I recently purchased the get to work expansion pack but when I tried to download it I would immediately get an unknown error message after about 2 percent of it being downloaded. I've restarted my MacBook, cleared the cache thoroughly, even going so far as going into my computer library and cleaning out all the EA and Origin folders, reinstalled the EA app and of course restarted the EA app. Nothing has helped and this is my last resort, I've put in an error report too, no response yet.
