Like the iPad and iPhone, Mac Desktops and Laptops have a view similar to the Home Screen. The Mac’s version of the Home Screen is through an app called, Launch Pad. You may use the icon on your Dock (displayed at left), Finder, or a multi gestured 5 Finger Pinch on your touch pad or touchscreen.
My Launch Pad view displays below. Notice, like an iPad or iPhone, I have multiple screens that I may swipe or click through.
