I can't log into my iMac desktop - it keeps telling me my password is wrong!
Two days ago out of nowhere my iMac starts telling me that my login password is wrong and I cannot get into my desktop without changing it with my Apple ID. I canged the password and tried to log in again - it tells me that the password is wrong but lets me get into my desktop anyway. When I get in various windows pop-up wanting my login-keychain, which I type in and what do you know - It says it's incorrect! I don't know what else to do, any help or advice would be greatly appreciated, thanks in advance!
iMac, Mac OS X (10.6.5), 27" core i7
