Resetting the original administrator account password
Follow these steps to reset a password when there is only one administrator account on the computer, or if the original administrator account needs a password reset. "Original" administrator account refers to the one that was created immediately after installing Mac OS X. If the original administrator password is known, that administrator account may be used to reset the passwords of other administrator accounts using the steps described above.
- Start up from a Mac OS X Install disc (one whose version is closest to the version of Mac OS X installed).Â Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C). Or, you can useÂ Startup Manager.
- Choose a language, click the arrow button to continue, then chooseÂ Reset PasswordÂ from theÂ UtilitiesÂ menu (or from theÂ InstallerÂ menu, if using Mac OSÂ XÂ 10.3.9 or earlier).Â Tip: If you don't see this menu or menu choice, you're probably not started from the CD yet.Â
Note: The default keyboard layout is U.S. English while started from the installation disc. If you use a keyboard layout other than U.S English, use the Input menu (the flag icon on the right side of the menu bar) to select the desired layout before typing a new password.
- Select your Mac OS X hard disk volume.
- Select the user name of yourÂ originalÂ administrator account.
Important:Â Do not select "System Administrator (root)". This is actually the root user. You should not confuse it with a normal administrator account.
- Enter a new password.
- Click Save.
