Cannot sign in to iTunes 12.9.5.5. with my AppleID
I am not able to sign in to iTunes with my Apple ID on my MacBook running Mohave. This happened only recently. I'm prompted for the ID and password, but when I hit enter there is no confirmation of any action. My data connection is fine and my account is in good standing and has not been revoked. I was able to sign in on my wife's MacBook Air just fine. Thanks for your direction.
