Apple MacBook Password Recovery

I had an interesting task at work last week. I had to remove pasword from a MacBook. Doesn’t sound like much., his family, his work and his interests. None of them worked. This called for a more subversive approach.
I did some searching on Google and found a page that discusses how to hack passwords on a Mac. Various methods suggested on several pages of comments to that page had failed. Figuring I had nothing to lose I decided to try mixing the methods I had found until I found one that worked. I figured if I hosed the machine at this point it wouldn’t be a big deal. The machine was useless to me in it’s current state anyway so I would have had no qualms about clearing the hard drive and starting from scratch. The only reason I was still going at it was for the challenge. So off I went.
After only about 2 or 3 tries I came across the following method that worked for me:

1. Click Restart at the login window
2. While the computer is restarting, hold down “Command-S” until you see text scrolling through the window. This boots the computer into single user mode.
3. At the Localhost% prompt type:
   

   /sbin/fsck -y [Enter]
   /sbin/mount -uw / [Enter]
   sh /etc/rc[Enter]

4. When the Localhost% prompt reappears, type:
   

   passwd [username]

   (Replace [username] with the username you want to change and leave out the brackets.)
   You will then be prompted to type a new password for this user 2 times.
5. After entering the new password, type:
   

   reboot

6. At the login window, enter the username with the new password.Voila!
