    Hi, is there a way to turn off shell on startup (command + S when the computer starts up). I realized that this is a great way for someone to screw with a Mac. For example, they could type in "rmdir Users" and then my USERS folder is gone! If I didn't have a Time Machine backup, I would be dead! Is there any way of disabling this? Thanks!

    Yup, that's the way to go. Note that this disables ALL startup key combos (such as those that allow you to boot from DVD, select startup volume, etc). Here's the Apple article:


    Funnily enough, Apple recommends that you not use an uppercase letter "U" anywhere in your password :p
