I had negligent reset system administrator user password from utility menu via 10.5 installer disk from Mac Mini (intel base)  on iMac G4 10.4.11. But,I don't have 10.4 installer disk . How can I solve this trouble? I tried to create new root user in single user mode, but It doesn't work. Now, I stuck in log in screen with blank user and password.


iMac, Mac OS X (10.4.11)

    Hi, not ckear, dud you try this...


    Reset OS X Password Without an OS X CD...



    Admin Hack...



    Starts up like the first time you buy a new Mac, but after filling in all that info again, you should have access to the computer and the other Users & files will still be there... give the new User a different name than an existing one.

    Tough without the Install disc, but some things to try...


    Does it boot to Single User Mode, CMD+s keys at bootup, if so try...


    /sbin/fsck -fy


    Repeat until it shows no errors fixed.


    (Space between fsck AND -fy important).


    Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

    If you can afford to erase everything, try this...


      1. Insert the Mac OS X Install disc r, then restart the computer while holding the C key.

       2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)

          *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

       3. Click the Erase tab.

       4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

       5. Select your Mac OS X volume.

       6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion hopefully you'll be able to get a good install.
