keychain issues with resetting
For one of the users on my iMac, a password was changed. Now, for this particular user, we constantly get error messages involving 'login' keychain. I tried to reset the keychain; but, I keep getting errors. first it gave me a Unix[Invalid argument], then it gave me a 'specified keychain cannot be found" message. I'm running OSX Version 10.9.5. Can you please provide instructions or a link that addresses these error messages. I have a feeling this particular keychain has now been deleted based on the error message. If that's the case, how do I create a new keychain and make sure it is tied to all the files / programs for this particular user? Many thanks.
iMac (27-inch Mid 2011), Mac OS X (10.7.4)
