Apple Mac Computer - "The system was unable to unlock your login keychain" Message

After changing or resetting your Palm Beach State College password on a Mac computer, you will receive the message "The system was unable to unlock your login keychain" while logged into the Apple computer with your new password. This is because Apple's keychain is still trying to authenticate with outdated credentials for your account.

The system was unable to unlock your login keychain.


  • If you select Create New Keychain (quickest solution), your PBSC account password and keychain password will now match again.
  • If you select Update Keychain Password, you will need to know your previous PBSC account password. When prompted, enter in your previous PBSC password, then select OK. The keychain credentials will update to your most recent password, and the computer will bring you to the desktop.

Enter in your password, then select OK
