Downloads won't work on Origin

hi guys

my wife is using Sims4 on her mac and it works fine. However recently she purchased some update and there is no way in **** to have it installed. While Origin app is open i can find expansion pack and it shows as owned. However, in order to use it i need to download it first. And this is where problems starts. When clicking download nothing happens. I've googled possible resolutions and nothing works. Tried deleting the cash, reinstalling game and Origin. Started system in safe mode. Tried root access to origin app. nothing works.

Anyone had this same problem and found the solution?

thanks
