How do I reset the administrator password on a mac running Os 10.6.8 without an installer disc

[iMore Question]

Notebook was bought refurnished with no software. Was given the wrong administrator password. Can not connect to apple support with my mac notebook. I don't know if they set an apple id.

[h=1]Snow Leopard 10.6 password reset, no disk.[/h] This only works for Snow Leopard.


1: Reboot the computer and hold the command and s keys down to enter single user mode.

You will need a wired/built in keyboard, a PC one will work, the Windows key is the commnad key.

(if a lock appears and a password request, there is a firmware password, you have to know it or take it to Apple to fix it)

2: When you get control, type fsck -fy and press enter, it will take a bit to finish

3: Next type mount -uw / (there is a space before and after -uw) this mounts the drive

4: Next type ls /Users this will list the Users on the machine so you can get the name

5: Next type passwd username (where username is the name of the account)

6: Enter the new password twice, you won't see anything.

7: Once inside, your going to have problems with Keychain.
