Anyone know why the keychain keeps prompting my login keychain password after waking from sleep? Using Yosemite but it was also happening in mavericks...keeps prompting for imessages and icloud after waking up from sleep, even though it's not locked. I have set the keychain to lock when sleeping but after waking and unlocking it still keeps asking for my login keychain password for imessages and icloud. So, is this normal behavior? Thanks for the feedback.
