Hi guys, just spent quite some time on resetting macbook pro password, and I know how to do it! now!!!
All you need to enter terminal and create a new admin account:
2. Hold apple + s down after you hear the chime.
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):
* mount -uw /
* rm /var/db/.AppleSetupDone
* shutdown -h now
4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you're good to go again!
soooo easy-hope this helps someone.
