Our goal with MacBook was to do the impossible: engineer a full-size experience into the lightest and most compact Mac notebook ever. That meant re imagining every element to make it not only lighter and thinner but also better. The result is more than just a new notebook. It's the future of the notebook. And now, with sixth-generation Intel processors, improved graphics performance, faster flash storage and up to 10 hours of battery life, MacBook is even more capable. The moment you open your MacBook, its gorgeous 12-inch Retina display with edge-to-edge glass brings everything into focus. Every photo leaps off the screen in rich, vibrant detail. Over 3 million pixels render each letter with crystal clarity. And it all comes to light on the thinnest Retina display ever on a Mac, meticulously honed to deliver a bold visual experience within an impossibly minimal design. We believe that a comfortable, full-size keyboard is essential for a great notebook experience. But to fit one into the elegantly thin MacBook, we had to completely rethink how a keyboard is engineered and constructed. We redesigned each key and its underlying mechanism - not only making the whole keyboard much thinner, but also allowing for more comfortable, precise and responsive typing that just feels right. OS X is the operating system that powers everything you do on a Mac. With OS X El Capitan, it's simple to do amazing things and delightful to do all the everyday things. And it works seamlessly with your apps and iOS devices.
