Why won't my MacBook Pro 10.9.2 take my Apple ID to sign into iCloud?
I've verified my Apple ID and iCloud is working on my iPad with this same Apple ID.
I have the same problem. After updating to 10.9.2
My ipad and iphone works perfect. It's a certificate problem. Try to reset the keychain http://support.apple.com/kb/HT5813
Didn't work for me, so I'm calling apple support or maybe reinstall maverick if they can't solved it
Maybe it works for you :-)
