Hey guys, I was wondering what the best way to lock down my Mac is. Just to be clear, I don't really care if people are able to log in / view my files when I'm not here. What I don't want is for them to be able to change the admin password and make system changes. I was wondering if my current solution is good enough: Admin password, set to automatic log in. (so deleting system files needs a password still) Firmware password, to prevent people from using the OS X restore disks to reset my admin password. Is this a good enough solution? Can people somehow reset the firmware password without knowing my admin password or vise versa?
