Enable firmware password on osx: This post will show you how to enable the firmware password on osx

firmware passwords will protect your mac from:
booting from a cd or dvd
booting from the diagnostic utility on the install dvd
booting from the network

to enable the firmware password you need to boot your mac from your install disc [hold ‘c’ during startup]
once the cd has booted select
