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 film playback. And with up to 30 days of standby time, you can go away for weeks and pick up where you left off. 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 ultra-fast. And all that power is encased in an incredibly thin 1.7 cm unibody design that weighs only 1.35kg. 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. 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. Part of what makes MacBook Air so responsive is that it's designed entirely around SSD storage. Not only does this make MacBook Air much lighter and more portable than traditional notebooks, it also provides faster access to data. Available in capacities up to 512GB,3 this PCIe-based SSD storage is up to 17x faster than a traditional 5400 rpm notebook hard drive.4 So when you flip open MacBook Air, it's ready to go straightaway. Even after a month in standby mode, the screen springs to life. Connect your MacBook Air to your devices and displays with a Thunderbolt 2 port that's twice as fast as the previous generation. But that's not the whole story. MacBook Air also comes equipped with two USB 3 ports, so you can connect the latest USB3 devices and all your USB2 devices as well. With just a few connections, MacBook Air transforms from an ultra-portable notebook to a complete workstation.
