Keychain has popped up recently with a message saying: Messages Agent wants to use the "local Items" keychain. Please enter the keychain password. I've tried every password I can think of and nothing works. Any ideas on how to get rid of it? Cancel doesn't work, the "?" icon won't open. Since this has happened my computer is also extremely slow. Any thoughts?
Thanks,
