Messages app won't let me sign on (thinks my password is wrong)
Messages has been working fine up until a couple of days ago. Now when I try to login, I enter my Apple ID and password and it rejects my password. After it failed, I went into iTunes store and clicked on Account from the store homepage. Even though you may already be logged into the store, going to the Account page always requires you to enter your Apple ID and password again. And it worked fine so I know nothing went screwy with my AppleID or password on Apple's end. So the problem seems to be with the Message application in 10.8.2.
Any idea what's going on?
