Is there a magic key?

Reboot from your original OS installation disk, go to Utilities and choose Reset Password. Choose the admin user and create a new password.

Changing your administrator password

http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh655.html

Here's one method to reset the password without the install disc:

1. boot computer and hold the "apple" key and the "s" key.

2. wait for terminal show

3. release keys

4. type without the quotes: "/sbin/mount -uaw"

5. press enter

6. type without the quotes: "rm /var/db/.applesetupdone

7. press enter

8. type without the quotes: "reboot"

9. press enter

This will let you create a new admin account when you reboot your computer.

Also, without the discs, look at Mac OS X Tip - No Password, No Root, No CD? No Problem.

Here is a way to get around not knowing the admin password on Macs.

To reset your OS X password without an OS X CD you need to enter terminal and create a new admin account:

1. Reboot

2. Hold apple + s down after you hear the chime.

3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):

* mount -uw /

* rm /var/db/.AppleSetupDone

* shutdown -h now

4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!
