Mac OS X Lion includes over 250 new features that will transform how you interact with your Mac. OS X gives you long battery life by dimming the screen in low-light conditions and even regulating processor activity between keystrokes. 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 works with the processor in your Mac to deliver the best possible performance. 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. Hardware and software made for each other. Mac OS X Lion is the next major release of OS X, the world's most advanced desktop operating system.
