iTunes won't acknowledge my Username / Password on my Macbook.
I'm signed in to iTunes on my iMac. When I attempt to sign in to iTunes using exactly the same Username and Password as my iMac nothing happens - there's not even an error message, I simply remain signed out despite the Username and Password having seemingly been accepted.
Can anyone assist please? Cheers.
