Because we design software that works hand in hand with our hardware, you get a better operating system. Built on a rock-solid UNIX foundation, OS X is engineered to take full advantage of the technologies in every new Mac. And to deliver the most intuitive and integrated computer experience possible. 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 architecture in your Mac to deliver the best possible performance. Mac notebooks include a Multi-Touch trackpad that lets you pinch, swipe, and tap your way through every app on the system. OS X gives you long battery life by dimming the screen in low-light conditions and even regulating processor activity between keystrokes.
