I can't sign in to the app store. I've reset my password twice, tried safe boot, run Onyx compatible with El Capitan 10.11.1. I just get the spinning sticks, and then I have to force quit to get out of it. The problem appeared after the update to El Capitan.
Following your advice re Console, this is what I got:
