Are you using a EFI password in the firmware? If so you can try this.

 

If not here are a few ways to reset your password. After your done I would read up on how to close these security holes. Macs are extremely easy to hack into until you spend the time to secure it.


• Power on or restart your Mac. 
• At the chime (or grey screen if your chime is turned off), hold down Command+S on your keyboard to enter single-user mode. 
• This step is optional, but it’s a good idea because it checks the consistency of the hard disk before moving on. At the prompt, type fsck -fy and press Enter/Return. Wait for the checks to complete before going to the next step. 
• Type mount -uw / and press Enter. 
• Type launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist and press Enter. 
• Type ls /Users and press Enter. This lists all of the usernames on the computer – helpful if you don’t know or remember what these are. 
• Type dscl . -passwd /Users/username password and replace “username” with one of the users displayed in the previous step. Replace “password” with a new password of your choice. Press Enter. 
• Type reboot and press Enter.

 
• Reset 10.4 Tiger password

• Power on or restart your Mac. 
• At the chime (or grey screen if your chime is turned off), hold down Command+S on your keyboard to enter single-user mode. 
• Type sh /etc/rc and press Enter/Return. 
• Type passwd username and replace “username” with the short name of the user account for which you’d like to reset the password. 
• Type your desired password and press Enter. It won’t show itself on the screen, so be careful what you type. You will most likely have to enter it again to confirm. 
• Type reboot and press Enter.


• Tricking your Mac into creating a new user account 
• Power on or restart your Mac (should work for any Mac OS X system). 
• At the chime (or grey screen if your chime is turned off), hold down Command+S on your keyboard to enter single-user mode. 
• This step is optional, but it’s a good idea because it checks the consistency of the hard disk before moving on. At the prompt, type fsck -fy and press 
• Enter/Return. Wait for the checks to complete before going to the next step. 
• Type mount -uw / and press Enter. 
• Type rm /var/db/.AppleSetupDone and press Enter. 
• Type shutdown -h now and press Enter.

The third method of resetting your Mac’s password requires some additional explanation. Rather than simply changing the password like the previous two methods do, this one fools the operating system into believing it has never been started before. This means when you restart the machine, it will take you through the entire setup & registration process all over again. Do not worry, all of your pre-existing data is still available. Just continue with this process and do not choose the option to transfer or migrate information to the Mac.

Once you’re done, log in with your new admin account and go to System Preferences > Accounts. You may have to click on the lock icon in the lower-left corner before making changes here. You should see your original user account(s) in the left column. Try clicking on one of them to convert it to a standard user account (uncheck “Allow user to administer this computer”) and change the password. You should be able to successfully log in to that account now and access all of your files and programs. If you want, you can log back in with your new admin account and re-check the “Allow user to administer this computer” option in System Preferences to grant admin privileges to the original user again.

That should cover it! As always, remember messing with single-user mode and Terminal is risky and may lead to trouble if you make mistakes. Considering you’re already locked out of the computer, though, you’ll probably be willing to take your chances at this point.

One last thing… if you have a Keychain Access password, you will probably need to reset that as well. You can do this by selecting “login” under Keychains on the left and choosing Delete from the Edit menu. You’ll lose everything in the Keychain, but you’ll now be able to start fresh and add new ones.
