I find that I'm visiting RixStep on a regular basis these days. Today I stumbled across this post
about using root privileges and thought I'd share it with you. If you want to learn more about using Mac admin privileges, this might not be the best post to start. If you already have some familiarity with the command line and with Unix, you can learn more about what su does, how to authenticate yourself, and understand why this affects security in a handy ten-point check list. It's a little verbose, but there's a lot of good meat in the article.
