Do you have system installation disks, either that came with the computer, or that have the same operating system version? If you boot off the system installation disks, you can reset the master password and create a user account, even without reinstalling. I think the disks must be the same version as the currently installed OS to avoid re-install though.

EDIT: I hope you obtained a computer, for which you have no passwords, in a LEGAL way.... :(

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 (of several) 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, the original administrator user may reset the passwords of other administrator accounts using the steps described above.


Start up from a Mac OS X Install CD (one whose version is closest the the version of Mac OS X installed). You should first disable Open Firmware password protection, if it is enabled. Hold the C key as the computer starts.

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.

Select your Mac OS X hard disk volume.

Set the user name of your original administrator account.
Important: Do not select "System Administrator (root)". This is actually a reference to the root user. Do not confuse it with a normal administrator account.



Enter a new password.

Click Save.

Well, it is a little late (as people jumped to give an answer), but more information on how you found this PowerMac G4 seems in order.

Macs (even older ones) aren't usually just lying around to be found. And sellers (legitimate ones) usually give that type of information to the buyer.

In my experience around these forums, many people don't like giving advice for something they think might be illegal. I think its a good quesiton and I wouldn't have helped without more info either.

True, I try to give people the benefit of the doubt, but it still sounds pretty fishy to me. :rolleyes:

Yes unless you use fire vault, keep confidential data in encrypted .dmgs or set an Open Firmware password that doesn't allow booting from CD.

I guess I'm the person smart enough not to give out answers that could be used for illegal purposes without asking a few basic questions first.

:rolleyes:

And I guess you are one of the people who didn't think about the consequences of blurting out an answer without asking those basic questions.

Does that put our relative positions on this issue into perspective for you?

Also, sometimes this works, but if you boot into Single-User mode - hold down the s key while starting, and type in passwd root you can change the root password - provided root was enabled very firstly. You can also make a user by like... adduser or something like that I think, not sure, but I think you can.

Bingo, you win a prize I'm the one that doesn't give a ****! Are you the person smart enough to realize that the info is all over the web, even on Apple's own site, which is where I pulled the answer from. Besides, I didn't ask you if your the person smart enough not to give out answers. The question I asked you was, who are you to question how he found it?

No -- the root password is just an OS software thing. The way to set the OF password, which is in hardware, is at this link:

Be forewarned.... you're pretty much on your own if you somehow forget it. :(
