I have forgotten my macbook password

Do a google search for reset lost password in Mac OSX.
Here are two responses from such a query:
see http://www.wikihow.com/Reset-a-Lost-Admin-Password-on-Mac-OS-X
or
http://coolestguidesontheplanet.com/reset-forgotten-admin-password-mac-osx/

Both contain specific steps too long to mention here.

HI,
The simplest way may be to use the Recovery HD, but this won't work if you have FileVault enabled.

Boot into Single User Mode and remove a setup file

• Restart the Mac holding down the Command+S keys, this will take you into Single User Mode and it's Terminal interface
• You'll need to check the filesystem first:
fsck -fy

• Next, you must mount the root drive as writeable so that changes will save:
mount -uw /

• Now, type the following command exactly, followed by the enter key:
rm /var/db/.applesetupdone

• After removing the applesetupdone file, you need to reboot, type 'reboot' and hit enter

Stage 2) Create a New User Account upon System Boot
You aren't finished, but the hard part is now over - no more command lines, you'll now be in the familiar Mac OS X GUI to finish the password reset process. In this step we just create a new user account as if you just got a new Mac:

• Upon reboot, you will be presented with the traditional "Welcome Wizard" startup screen just like when you first get a Mac
• Follow the welcome wizard and create a new user account - making the account name different from the account whose password you want to recover
• Continue on and boot into Mac OS X with this newly created user account, this new user account is an Administrator and has administrative access

Stage 3) Reset the Forgot Password via System Preferences
You are almost done, now you just need to reset the forgotten user account password using the Accounts control panel:

• Once you are booted into Mac OS X, click on the Apple logo and then navigate down to "System Preferences"
• Click on the "Accounts" icon in System Preferences
• Click on the Lock icon in the lower left corner of the "Accounts" preference window and enter the newly created user credentials, this enables you to change other user accounts and reset other users passwords
• On the left side user panel, select the user account containing the forgotten password
• With the user of the forgotten password account selected, click on the "Reset Password" button
• Enter a new password for that user, be sure to include a meaningful hint so you don't forget it again!
• Close System Preferences and reboot the Mac
• You can now login to the previously inaccessible user account using the newly reset password! All user files and settings are maintained as before the password was forgotten

Optional: If you'd like, you can delete the temporary account you created to reset the users password. This is wise for security purposes.

all you have to do is insert the osx install disk that your computer came with (or if you bought a newer disk that one) insert that, restart the computer, and then click on the "forgotten password tab"

You need the OS Install DVD - which has utility to reset your password.

Follow these steps to reset a password when there is only one administrator account on the computer, or if the original administrator account needs a password reset.
Reset MAC original administrator account password

By not being more specific, when you note that you are locked out of your Macbook, I would have to presume you are referring to your User Administrator account or you have a FileVault password which is prompted for, upon booting up and you have forgotten that password.

Not sure which could be the case, so I will 1st provide you steps for resetting your Administrator password with your Mac OS X installation disc and 2nd, provide you, a key Apple support link, for fixing the forgotten FileVault password (just in case this is the culprit, which is locking you out of your Macbook).

BOOT TO TIGER/LEOPARD DISK-
• Place your installation Disk (Tiger or Leopard I presume) into your drive and
allow it to load.
• Restart your Mac
• As soon as you hear the Apple Chime, press the "C" key on your keyboard
and hold it.
• You will see a White Screen, Grey Apple first, do not release the C key until you
see a Spinning gear.
• Once you see that Spinning gear, release your C key and allow the disc to
continue loading

- RESETTING ADMINISTRATOR PASSWORD-
(Works for both Mac OS X 10.4 (Tiger) and Mac OS X 10.5 (Leopard))

• When the booting to the Mac OS X disc is completed, you will now be in the
Installer environment
• Enter to next page, look up on upper left corner you should see "Installer" near
the Apple menu.

• Two spaces over you should see Utilities. Click Utilities>Reset Password.
• Select your user name from the drop down list and reset your password.
• When you are done, simply exit the Reset Password and Installer and reboot.

• At the Login window, enter your new password and you should be back into your home User Administrator account.

You shouldn't need to install anything off the CD. Simply plug your Macbook into the DIR-300 via ethernet (making sure you manually set your Macbook's IP to 192.168.0.x (where x is anything from 2-254). Then open up your web browser and type 192.168.0.1 into the address bar. This will log you into the DIR-300 (I think the default login is "admin" with no password).

Refer to the manual for the configuration for the rest of your setup.

Insert your 10.4 or 10.3 Boot disk. If youve upgraded to tiger, use that dvd. DO NOT USE COPIES!!
