Ea APP doesn't work on IMAC

Hello! I have an Imac (I have the version that makes origin not work for me) so I installed Ea app. Yesterday I wanted to play SIMS 4 and everything went perfectly. That same evening I wanted to play sims 4 again. The problem is that Ea APP won't open anymore because there seems to be a problem with my account ( that's what the message says, but i don't know if its really that )  and I don't know what to do! help me please
