    Hello, depends if it's a login Password, or a Firmware Password...

     

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

     

    2. When your computer finishes starting up from the disc, choose Utilities from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

     

    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access the Menubar at top.

    Starts up like the first time you buy a new Mac, but after filling in all that info again, you should have access to the computer and the other Users & files will still be there... give the new User a different name than an existing one.

    It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.

     

    Force Removing Password Protection

     

    1) Add or remove DIMMs to change the total amount of RAM in the computer.

     

    2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).
