This document explains how to reset a forgotten account password in Mac OS X for versions 10.6 and before.
Warning: Do not use the instructions in this document to reset the password for a FileVault protected account. Doing so may render the contents of the account inaccessible. Instead, follow these instructions provided by Apple.
To reset a Mac OS X account password, startup the computer using an Apple Software Restore disc (included with newer Macs) or a Mac OS X Install disc. It is best to use the same disc from which OS X was installed. Do not use a disc with a version of OS X other than the one installed on the computer or it may not work. For example, if you reset a password on a computer running Mac OS X 10.3 with an OS X 10.4 disc, you will not be able to log into the account.
Insert the disc, restart the computer, and hold the C key when you hear the startup sound. You can release the key when the gray Apple appears.
It is normal for the computer to take longer to startup from a CD or DVD. The disc will automatically start the OS X installer but you do not need to reinstall OS X. If you are prompted to select a language and you do not see the menu bar at the top of the screen, click the right arrow button to proceed to the next step.
The method of resetting passwords varies slightly depending on the version of OS X on the installation disc.
|Mac OS X 10.2.x through 10.3.x:
Select Reset Password from the Installer menu.
|Mac OS X 10.4.x and 10.5.x:
Choose Reset Password from the Utilities menu.
The Reset Password window should look similar to this:
To close the password reset utility, select Quit Reset Password from the Reset Password menu.
Restart the computer by choosing Quit Installer from the Installer menu and click Restart or Quit when prompted.
Resetting an account password does not change the Keychain password. For security reasons, there is no way to reset a forgotten Keychain password and the contents of the keychain cannot be recovered. The Keychain must be deleted so a new one can be created and used.
From the Finder, click on the Go menu and select Home.
In the window that appears, open the Library folder and drag the Keychains folder to the trash.
Restart the computer or log out and log back in. A new keychain will be created using the current account password.
