Resetting Administrator and password on Power Mac G5 without start up disks

no

Hey, welcome to the forums. Unfortunately, there is no method of resetting the administrator username and password without the Mac OS X install disks. If you've lost your install disks, you can order replacements from Apple. You should contact AppleCare and see what they'll do for you.

what happened to your install disk?

No, even if it'll work it's against the SLA. Try this instead:

"This computer was sent to me by one of my partners without the install disks and now they can't locate them."

Then contact Apple and get a replacement set.

Is it possible to reset the user name and password without the start up disks and if so how can it be done?

Do you know the password for an existing user account? If so, just log in as that user, go to the Accounts system preference & click the "Change Password..." button to change it. You can also change the 'long' user name to whatever you want in the "User Name" box in that same preference.

However, if you want to change the 'short' name of any account (the one used for the account's home folder, the Reset Password utility on the Mac OS X Install disc won't help -- it just allows anyone that can boot the Mac with that disc to reset the admin password, but not change the user short name associated with it.

To do that follow the procedure in Mac OS X: How to change user short name or home directory name. Of course, to do that, you need to know the password for an admin account (to enable the root user), so if you don't know the password for any admin account, you would need to use the reset password utility from an installer disc.

AFAIK, any Mac OS X Install disc capable of booting the Mac in question can be used for this, & using one that you don't actually own should not violate the software license agreement, since you are not using that disc to install anything.

there is a way to change the password u need to access single user mode:

single user mode reset password: leopard

1) type
mount -uw /
2) type
ls /users <--- will list the user accounts on mac
3) type
passwd (user's name)
4) (enter the new password cannot be seen then verify password)
5) type reboot

Hi there, need help please..just bought a used MAC BOOK PRO and I'm new to Apple Discussion. When Im trying to install a new program, a window message asking for Username/Password. Called the seller can't recall the Password since it was only handed down to him by a relative which nowhere to be found?? Anyway, I've tried restarting with Install Disc with C pressed down and went through the procedure but when I tried selecting UTILITIES>RESET PASSWORD same window asking for the Username/Password. What must I do? (Much appreciated)
