Reset password using Lion Recovery
If you bought a brand new Mac with Lion pre-installed, it includes a recovery partition with various system recovery tools. One of them allows you to reset your Mac’s password:
- Shut down your Mac and turn it back on while holding down the ⌘ and R keys at the same time until you see the Lion Recovery screen.
- From the menu bar at the top, select Utilities > Terminal.
- In the Terminal window type resetpassword and press Enter.
- Use the Reset Password utility to select your startup volume, choose your user account, and enter a new password.
