of iCloud and then log in again using your Apple ID and new password.
FaceTime has it's own set of preferences and log in.
You "may" have to log OUT of FaceTime;
Facetime > Preferences > sign out
Then log back in again with the new password
Hope that helps
I had set up FaceTime for my friend when she got a new MacBook Air and it worked fine. Recently, she has been unable to login into FT and the preferences tab is greyed out.
This happened after she reset her iCloud password as she had forgotten the earlier password. iCloud also took some time to log back in but eventually works fine.
Except she is unable to login into FaceTime anymore. I had her restart her computer several times, and login and logout of iCloud a few times too. I also asked her to wait and login after some days but none of this has worked.
A friend made the rather drastic suggestion that she may need to reset her Apple ID completely.
Please suggest a way out. Thanks!
