Thanks. But it looks like the "Firmware Password Utility" is not available by default in OSX 10.9, and those instructions only describe how to get it for OSX 10.5 and below. Thoughts?
You have to boot into your recovery partition (Cmd+R on boot), then there's a menu option to set the firmware password, which will be active on the next reboot.
