Are you ready for some unauthorized Mac goodness? Would you like to easily get into someone's mac? Apple makes it easy as pie (no pun intended - honest).

If you have The Mac OS DVD then you can boot to it and reset account passwords! As far as I know this will work for Panther and Leopard.

When they showed this to me in class my hand shot up and I wasn't the only one. This is a huge security flaw (feature) and would not fly in my environment.

Have you Mac fan boys know this? Have you been keeping this from The Admin? Oh well back to class.
From The Apple Support Site:

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.
