On Mac you only get one row of tools across the top. You'll use View>Customize Toolbar and drag icons to or from the toolbar as desired. Otherwise, under View>Tool Palettes, you can choose the various tool palettes you wish to display but they will be floating, not docked as in the tutorials you've probably seen. Those tutorials were probably done on windows machines which can handle multiple rows of tool bars across the top and they dock above the drawing space.
