How to Recover an Administrator Password for a Mac

When you first set up a new Apple laptop or desktop computer, you are prompted to choose a username and password. These credentials are used to create an administrator account, which is required for installing new software and updating applications. If you have forgotten the administrator password on your Mac, use the Mac OS X installation DVD to recover and reset it.
