    You need to give details of how your attempts failed.

    Here's the instructions if you have the discs.

    Mac OS X: Changing or resetting an account password



    Changing your administrator password



    Here's one method to reset the password without the install disc:


    1. boot computer and hold the "apple" key and the "s" key.

    2. wait for terminal show

    3. release keys

    4. type without the quotes: "/sbin/mount -uaw"

    5. press enter

    6. type without the quotes: "rm /var/db/.applesetupdone

    7. press enter

    8. type without the quotes: "reboot"

    9. press enter


    This will let you create a new admin account when you reboot your computer.


    Also, without the discs, look at Mac OS X Tip - No Password, No Root, No CD? No Problem.



    Here is a way to get around not knowing the admin password on Macs.


    To reset your OS X password without an OS X CD you need to enter terminal and create a new admin account:


       1. Reboot

       2. Hold apple + s down after you hear the chime.

       3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):

              * mount -uw /

              * rm /var/db/.AppleSetupDone

              * shutdown -h now

       4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!
