iCloud login problem on iMac
I am not able to login to iCloud on my iMac. When I go to Preferences->iCloud and type in my Apple ID and Password, it kepts saying "You can't sign in at this time". I am able to login to iCloud using the same Apple ID on my iPhone and iPad. If I change to another Apple ID on my iMac, then I am able to login.
So it seems that my Apple ID is somehow locked and not acceoted on my iMac.
Appreciate your help. Thank you.
iMac, Mac OS X (10.6.5)
