How can I get my Apple TV to accept the new password entered for Apple i tunes on my computer??Right now it wont turn on.
If you updated your Apple ID, then that might have activated two-factor authentication.
If you have an Apple TV (2nd or 3rd generation) and two-factor authentication for your Apple ID,
then you would need the adjusted sign-in procedure to incorporate the verification code.
