Apple TV login loop on Mac despite existing account
I've had this problem for three days. I can watch on my tv but not on my Mac. I've tried turning on and off my computer, reloading etc.

Original Title: My Mac will not sign me in to watch Apple TV. It keeps looping me back to the login page and asking if I want a free trial. I have an existing account.
