How to Reset a Firmware Password

Save

On an Apple computer running the Mac OS X operating system, you can set or change a firmware password. Creating a firmware will allow you to force users to log in when attempting to perform different system functions, like disc booting, safe booting and resetting the computer's PRAM. As an administrator, you can reset a computer's firmware password at any time by using the OS X installation disc.

Things You'll Need

  • Mac running OS X 10.5 or later
  • Mac OS X installation DVD
  • Insert the Mac OS X installation DVD into your disc drive, restart your computer and then hold down the "C" key as the system reboots.

  • Select the language you want to use when the installation DVD finishes loading.

  • Go to the "Utilities" menu at the top of the screen and select "Firmware Password Utility."

  • Check the box next to "Require password to change Open Firmware settings."

  • Enter the new password you want to use in the "Password" and "Verify" fields.

  • Hit the "OK" button to reset the firmware password and then quit the utility program.

  • Restart your computer again. Now when users try to perform firmware functions on the computer, they will be forced to enter the new firmware password.
