MacBook Air Make big things happen. All day long. MacBook Air lasts up to an incredible 12 hours between charges. So from your morning coffee till your evening commute, you can work unplugged. When it’s time to kick back and relax, you can get up to 12 hours of iTunes movie playback. And with up to 30 days of standby time, you can go away for weeks and pick up right where you left off. Thin. Light. Powerful. And ready for anything. Whatever the task, fifth-generation Intel Core i5 and i7 processors with Intel HD Graphics 6000 are up to it. From editing photos to browsing the web, everything happens ultrafast. And all that power is encased in an incredibly thin 0.68-inch unibody design that weighs only 1.35 kilos. 802.11ac Wi-Fi. Effortless wireless. Instantly connect to an 802.11ac base station — including AirPort Extreme or AirPort Time Capsule — and experience wireless performance up to 3x faster than the previous Wi-Fi generation. 802.11ac also delivers expanded range, so you can work more freely than ever. All systems go with SSD storage. The SSD storage in MacBook Air is up to 17x faster than a 5400-rpm notebook hard drive. So everything you do is snappy and responsive. MacBook Air even wakes up fast, thanks to SSD storage and fifth-generation Intel Core processors. macOS macOS is the operating system that powers everything you do on a Mac. macOS Sierra introduces Siri to Mac — along with new ways to enjoy your photos, shop more securely online, and work more seamlessly between devices.
