The first steps
Here we go. Welcome to Mac OS X Leopard!
This is pretty much how Mac OS X Leopard looks like after you finished the inital boot of your Mac.

You see the two main things the Desktop.
The menu bar at the top. It always stays there - not matter which program you have open. See the apple-icon to the very left in the menu bar. Click on it to access things like information about your Mac, System Preferences and also to shut down or restart your Mac. On the very right side of the menu bar you see different icons, such as the time, a little speaker (for volume control) and a magnifying glas.
This is Spotlight, which is used to search for all kinds of things on your Mac - files, folders, emails, dictionary entries, etc. We will cover Spotlight later. Of course you can play around with it. Just click on the icon to open the search box and enter something; e.g. “Leopard” (without the quotation marks). Just give it a try.
The dock at the bottom of the screen. It is used to launch programs and to indicate running programs (you see a blue light-spot below the icon). See also the folders on the right hand side (next to the trash bin). If you click on them, they open up in a nice way. Give it a try now. These two items - menubar and dock is what we will refer to in the future.
