Forgot Your Account Password

For Snow Leopard and earlier

Mac OS X 10.6- If you forget your administrator password

For Lion/Mountain Lion

Boot to the Recovery HD:

Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

When the menubar appears select Terminal from the Utilities menu.

Enter resetpassword at the prompt and press RETURN. Follow

instructions in the dialog window that will appear.

Or see Reset a Mac OS X 10.7 Lion Password and

OS X Lion- Apple ID can be used to reset your user account password.

If you are unable to boot from an installer DVD:

(these will only work on Leopard or earlier)

1. Boot to Safe Mode by restarting and after the chime press and hold down

the COMMAND-S keys until a black screen with white type appears.

2. At the prompt, type the following commands pressing return after each

command line:

/sbin/fsck -yf

If you do not receive a "Filesystem OK" message then repeat this command

until you do. If after seven tries you still do not receive a "Filesystem OK"

message, then the system is corrupted and needs to be reinstalled.

mount -uw /

cd /private/var/db/netinfo

mv local.nidb local.old

rm ../.AppleSetupDone

shutdown -r now

The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.

This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.

Reset Admin Password Using The Terminal

You can reset the password by printing out (or writing down) and carefully following these steps.

First, find the short name of the admin user on the machine. The easiest way of doing this is by looking at what the directory is called in the Users folder.

Now, start in Single-user Mode. It should boot into a command line.

Enter these exact lines. Press RETURN after each.

mount -uw /

ifconfig lo0 up

cd /var/db/netinfo

netinfod -s local

Now you'll need that short name. Enter "passwd", a space, and the short name of the admin. For example, if the admin was rather prosaically called "imadmin", you would enter "passwd imadmin".

The computer will now prompt you to change the password for "lmadmin" (or whatever the short name was). Go ahead and enter a new password.

Now, enter:

sync

reboot

and the machine will reboot. The admin password should now be changed.

HI PEOPLE PLEASE HELP ME...I FORGOT MY PASSWORD AND I NEED TO WORK NOW ON MY MACBOOK AIR 😟

Try resetting your password through single user mode:

1. Start your computer in single user mode: http://support.apple.com/kb/ht1492
2. The computer will show a black screen with white writing. Do not freak out. This is supposed to happen.
3. Type the following lines, and press enter after each line:

/sbin/fsck -fy

/sbin/mount -uw /

Important: Wait until you see the "root#:" prompt before typing a new line.

4. Choose the correct line below for your Operating System. Type the respective command and hit enter when you are done.

For Snow Leopard and Below:

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

For Lion and Above:

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

5. Now, type ls /Users

This will list all of the users of your computer.

6. Using the name of the account password you want to reset, type this:

dscl . -passwd /Users/USERNAME NEWPASSWORD

Make sure to type the username exactly as it appears in step 5. For example, if the username is "bob72", and you want to reset the password to be "123", you would type the above command as:

dscl . -passwd /Users/bob72 123

7. After executing the last command in Lion or newer operating systems, the computer may return an error about com.apple.DirectoryServicesLocal.plist. Ignore this message! If you properly typed the commands, the password reset worked anyway.

8. Once root# reappears, type reboot then hit enter. The computer will restart, and the account will have the new password.

9. Unfortunately, this process will cause problems with your keychain unless you suddenly remember your old password. When the keychain error appears, hit RESET KEYCHAIN. You will lose any saved passwords. While this is annoying, it is a necessary security feature.

I hope this helps!

The above lets you change your password easily in under 10 minutes, without any security questions or the old password.
