Hi;


Instructions for the Mac OS X Password Recovery.
Although there’s no real way to recover a lost root password, you can change the root password even if you do not know the current one. You must have physical access to the machine in order to accomplish this task.

1. Click Restart at the login window
2. While the computer is restarting, hold down “Command-S” until you see text scrolling through the window. This boots the computer into single user mode.
3. At the Localhost% prompt type:
/sbin/fsck -y
/sbin/mount -uw /
/sbin/SystemStarter
You will then see various services starting up.
4. When the Localhost% prompt reappears, type:
passwd [username]
It will then ask you to type the new root password twice, so do so.
(Though I’ve not tried it, it appears you can type niutil -list . /users to get a list if users if you do not know the username….if someone wants to verify this, I would be most appreciative).
5. After entering the new password, type:
reboot
6. At the login window, enter the username with the new password. Once you are logged in, you can use the Multiple Users application (/Applications/Utilities) to change your user’s password, or create a new user account.
Note: this may not work for newer versions of OS X; I think they did something about it in a security update. I hope this helps you with Macintosh password recovery.


Note: give some times between tasks, Follow to the letter.

Do you have any external harddrive attached to it? If so, remove it before restarting. Try to start it up in safe mode by holding the Shift button down at startup: http://support.apple.com/kb/HT1455

Something is wrong with the operating system. If there is a flashing folder with a question mark, then it might be with the hard drive as well. If you just get that warning, then you may only have to reinstall your operating system (OS X). Get your CD/DVDs out and insert the OS X disk. Hold down C when you start the computer so it will start from the disk and not from the hard drive. After the startup program has loaded, you can try to check the hard drive and repair permissions and such to see if that works, or you can just reinstall the OS. Good luck.

You don't need a "restore" cd.

You can just use any copy of Tiger.

Borrow one!

SOURCE: how to reset the master password for g4 mac powerbook ?

1. Obtain a Mac OSX install disc (buy one from apple or try Ebay) 2. Insert the disc then click on the "Install Mac OS" icon. Then click the restart button. 3. DONT INSTALL! Just click through enough of the windows to get to the regular set of choices on the menu bar. One of those choices is UTILITIES and one of the choices there is RESET PASSWORD.
Simple, but you should know that anyone with a Mac OSX install disc can gain access to your computer.
