    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.

    The exact message would be helpful. I doubt this is it:

      uknown puplic ato

     

    Let's establish exact machine specs.

    Here is how to find out what version of Mac OS you are running:

    Click on the blue apple in the upper left hand of the screen.

     

    click on this icon

    Picture 8.png

     

    Click on the first line, "About This Mac"

     

    Picture 9.png

    Most of these are numbers & that's what we want.

     

    What version & Processor do you have?

     

    --------------------------------------------------------------

     

    Get the Mac to set up  an additional administrative account.  You can then change the password on your old account.

     

    Start with your computer power off.  Hold down command-s. Power on your computer.  

     

    Type in the following:

     

    The first two commands will depend on your release of Mac OS X.  Look at what is typed out in the console to determine the exact format.

    # Type the follow two instructions to access the startup disk in read/write. Press return after each command.

    # in case of partial success repeat this command until errors go away.

    /sbin/fsck -fy

    /sbin/mount -uw /

     

    cd /var/db

    pwd

    #List all files. The l is a lower case L.

    ls -a

    #The move command acts as a rename command in this format.

    mv -i  .applesetupdone .applesetupdone.old

     

    # reboot  your mac

    shutdown -r now

     

    Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

    The above the idea came from a post by JoseAranda at September 9, 2006 3:48 AM

    http://www.askdavetaylor.com/how_do_i_reset_my_mac_os_x_admin_root_password.html

    You will need to scroll down to see this post.  Search for applesetupdone

     

    This method is mentioned in an apple support page without giving an explanation.

     

    Once you have a new administrative account, you can change the password of your old administrative account
