There is a new video on the MacTricksAndTips video channel. This video is all about setting up guest users. I like having a guest user on my Mac as it allows other people to use my laptop without having access to my account or the various settings. It is a great way to let people onto your Mac without them screwing it up.
Adding Guest Users
Guest users can be added under the system preferences option within the Users & Groups tab. You can get the latest videos from the channel by subscribing.
For some reason the audio on this video is a little up and down. It sounded find on my Mac.
