Resetting MAC Password without Reset Disk

[Satish]

If you forgot the password of your MacBook, then follow these simple steps to remove it.

Step 1: Reboot your system holding down the Apple key(Command key) and the ‘S’ key at the same time. By doing this, you’ll get unix like command interface.

Step 2: This way you have booted your computer as root user.

Now the commands to reset the password:

mount -uw /

launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist

ls /Users

(to get the username to reset if you do not know it)

passwd username

(username being the username you are resetting)

Now type a new password, eventhough it does not show anything on the screen. Type the same password two times.

rm -rf /Users/username/Library/Keychains/login.keychain

reboot

Not sure if it works on Mac OS versions below Leopard 10.5.x.

In Simple Words:

Restart your Computer, press and hold both Apple Key and ‘S’ key.
Once unix like interface appears, type these commands:

mount -uw / 
rm /var/db/.AppleSetupDone 
shutdown -h now 

Once the system restarts, your Macbook won’t ask for the password!

Note: Make sure to type the commands as is. If you provide wrong spacing and wrong case, it wont work :-(
