PowerBook G4 no password or installation discs

April 2018

Powerbook G4 is one of the best systems in its generation and people are keen to own one. However, it is not unusual for the user not to possess the system installation disks. These can easily be lost, misplaced, or the CD was broken and in some cases, when buying a Powerbook G4 second-hand, the disks would simply have not been provided by the seller. In this instance, the new user will probably want to delete all the history on the device but may not have the right disks and password. To do that, the system has to be restarted and after holding down Command+S, certain commands have to be written. Once done, reboot the system, and you will get your desired output.

I bought a PowerBook G4 from an individual without the installation discs. I don't have the system's password either. I need to delete the previous owner's info and set it up for me. I've reviewed previous discussions here but the instructions aren't working other than the disc check command. Can someone give me more detailed info on what to enter?
  • Restart your computer, hold down Command-S and type in the following:

/sbin/fsck -y [Enter]    
/sbin/mount -uaw [Enter]    
rm /var/db/.applesetupdone [Enter]    
reboot [Enter]
  • Once you've done that the computer reboots and asks you to set up an admin password. From there you just change all other account passwords in the account preferences
