Set a Hardware Password For Your MacShare
Many PC users are familiar with the idea of a firmware password that needs to be entered before the computer will load the OS. For PC power-users the BIOS or CMOS interface is familiar territory – and it’s the place where they set such a password.
Murphy Mac commenter Brian posted information on something similar for your Mac. Here’s the rundown.
Using the Open Firmware Password utility you can set a password on your Mac that will stop someone from resetting a user account password using the method described in this previous post. Essentially, it prevents unauthorized users from using a disk other than the machine’s internal drive to boot. The utility comes on the install disk that ships with your Mac.
Keep in mind this isn’t much additional security. It might slow down a casual attacker, but a determined foe with physical access to your machine can bypass this security. Your best bet for security that lasts is to encrypt your sensitive files using one of the methods described previously.| Permalink
