These features help tie together the entire interface, regardless of where the user might be within it. Using our real desktop analogy mentioned in part one of this series, let's expand upon it a bit more to help understand the way the OS is tied together. Imagine your actual desktop, now neatly arranged with your pens and pencils put away nicely in the top drawer, note pads set aside on one corner of the desk, while at the other end are printed papers organized neatly by subject. This is how Apple ships your virtual desktop. Everything has a place and a function.
Nothing is out of place and nothing is in an illogical position.
From here we start to customize our environment. The first thing that most users will do is change their desktop picture or pattern. We can do this, and many other things from the System Preferences. This application is neatly stored in the Dock or the Apple Menu so that it is both easily accessed and doesn't clutter up the virtual desktop environment. To open this item, either click it once in the dock or select it from the Apple Menu.
