The new MacBook Air is thin, light, and durable enough to take everywhere you go -- and powerful enough to do everything once you get there. A fourth-generation Intel Core processor and Intel HD Graphics 5000 deliver high performance, while using less power. So you get remarkable battery life: up to 12 hours on this 13.3-inch model. And with up to 45 percent faster flash storage compared to the previous generation and new 802.11ac Wi-Fi for up to 3x faster wireless, the new MacBook Air is quicker and more responsive than ever.
