Hardware and software made for each other.
Since the software on every Mac is created by the same company that makes the Mac, you get a fully integrated system in which everything works together perfectly. OS X works with the processor in your Mac to deliver the best possible performance. The Multi-Touch trackpad on every Mac notebook gives you more than enough space to pinch, swipe, and tap your way around most of the apps on your system. OS X gives you long battery life by dimming the screen in low-light conditions and even regulating processor activity between keystrokes.
Interact with your computer in a whole new way.
Tap, scroll, pinch, and swipe using Multi-Touch gestures, directly controlling what’s on your screen in a more fluid, natural, and intuitive way. When you scroll down on your trackpad or Magic Mouse, your document scrolls down. When you scroll up, your web page scrolls up. When you swipe left, your photos move left. And there are many more gestures that make all you do on your Mac the best experience you can have on a computer. Hands down.

Easy to use and incredibly powerful.
From the desktop you see when you start up your Mac to the applications you use every day, everything is designed to be simple and intuitive. Of course, making amazing things simple requires some seriously advanced technologies, and OS X is loaded with them. Not only is it built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability, it also delivers incredible performance, stunning graphics, and industry-leading support for Internet standards.
Easy access to all of your apps.
Working and playing on a Mac is all about apps, so OS X makes it simple to find and open those apps fast. The Dock is a handy place on your desktop for storing and launching your favorite apps, and it makes switching between them a breeze. The Dock also includes Stacks, folders that give you quick access to documents, files, and downloads. Launchpad is a full-screen home for all the apps on your Mac. It lets you arrange them the way you want, group them in folders, and delete them with ease. And apps purchased from the Mac App Store automatically appear in Launchpad, so you can browse thousands of apps and start using the ones you buy right away.
