If you have the discs available that came with the Macbook you can use the utility on them to reset the password. 1. Reboot insert the disc and hold the C key untill you get the welcome screen. 2. Click on the language you prefer and proceed as though you are going to reinstall the software. 3. At some point you will notice the menu bar at the top. Click on the drop down menu for utilities and you will find "Reset Password" If you do not have the discs available you can also use terminal to create a new administrator account and then reset the password. To do this 1.Reboot 2.Hold down the apple and S keys after you hear the chime. 3.At the text prompt enter these commands following each one with the return, • mount -uw / • rm /var/db/.AppleSetupDone •shutdown -h now

Hi I'm Peter , You can change your user password by going in with your administrator password. Here are a few helps https://iforgot.apple.com/password/verify/appleid and see

In OS X Lion or later, you can reset your user password with your Apple ID.

In Mac OS X v10.6.8 or earlier, 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. These steps require an optical drive; if your Mac does not have an optical drive and you have a Mac OS X v10.6 Install disc, see below.

  1. Start up from a Mac OS X Install disc (one whose version is closest to the version of Mac OS X installed). 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 use Startup Manager or the Startup Disk preference pane to select the Install disc.
  2. Choose a language, click the arrow button to continue,
  3. Mac OS X v10.6 or later: Choose Password Reset from the Utilities menu.
    Mac OS X v10.5 or v10.4: Choose Reset Password from the Utilities menu.
    Mac OS X v10.3: Choose Reset Password from the Installer menu.

    Tip: If you don't see this menu or menu choice, you're probably not started from the disc yet.

    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.
  4. Select your Mac OS X hard disk volume.
  5. Select the user name of your original administrator account.

    Important: Do not select "System Administrator (root)". This is actually the root user. You should not confuse it with a normal administrator account.

Changing your administrator password

To change the administrator password, you must know the current administrator password. If you're logged in as the administrator, open Account preferences and click the Change Password button.

If you don't remember the password and automatic login is turned off, you can reset the administrator password using the Mac OS X User Install disc.

IMPORTANT: Because a user with the Mac OS X install disc can gain unrestricted access to your computer, you should keep the disc in a safe place.
To reset the administrator password using the Mac OS X disc:

  1. Insert the Mac OS X Install disc and restart the computer.
  2. When you hear the startup tone, hold down the C key until you see the spinning gear.
  3. When the Installer appears, choose Utilities > Reset Password.
  4. Follow the onscreen instructions to change the password.
  5. Quit the Installer and restart your computer while holding down the mouse button to eject the disc.

Be sure to change your login password in Keychain Access to match your new password.

Changing Root/Administrator password for eMac G4...


Strong Warning: You should only enable root if you really really need it, really know what it's for, and realize the security implications of enabling root! You can do everything you need to do with "su do", so root is really not needed ... with that said, here's how to enable it - please understand what you're doing and why before you do this!

The "root" user (also known as the superuser) is the most powerful UNIX account. The root account can do anything to any file or folder, anywhere on the system. For that reason, it's considered quite dangerous, and only needs to be used (occasionally) by advanced users.

Because of the dangers of operating as root, Apple has chosen to hide the root account in OS X Final. However, there are a number of ways to enable it. The easiest is to boot off the install CD, and look under the Install menu for the "Password Reset" option. You can use this to change your own password if you forget it, and to enable the root account. This utility will not run if you copy it to your hard drive! It only works when booting from the CD.

Hi there
You'll need your install disk.

  2. Choose Reset Password from the Installer menu (or Utilities menu in Mac OS X 10.4 Tiger). Tip: If you don't see this menu or menu choice, you're probably not started from the CD yet.
  3. Select your Mac OS X hard disk volume.
  4. Set the user name of your original administrator account.

    Important:Do not select "System Administrator (root)". This is actually areference to the root user. Do not confuse it with a normaladministrator account.
  5. Enter a new password.
  6. Click Save.
