A Quick Look at the Mac OS X User Interface
Let’s take a look at the main components of the Mac OS X user interface. Figure 1-1 contains a screen shot of a typical Mac OS X user’s screen. The screen background, called the desktop , is light gray (you can change the color). The always-available Apple system menu at the top left opened when the Apple icon above it was clicked. The Mac OS X Finder is the active application , and thus its menu populates the rest of the menu bar at the top of the screen. The Finder window at the top of the screen is the active window , and its Info dialog is at the bottom left. (A dialog is a special type of window that gives information about or instructions to an application.) The Info dialog contains a number of labels that show information about the selected folder and a checkbox to set a folder attribute. It also contains a pop-up menu that can be used to change the view (information) that the Info dialog currently displays. We’ll discuss these screen objects in more detail later in this chapter.
