Used Apple 13.3" MacBook Air; 1.8GHz Dual-Core Intel Core i5, 8GB RAM, 256GB SSD (2017)

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.

Make the most of your day. From startup to sundown
Fifth-generation Intel Core processors in MacBook Air give you more time to do more things. Add that to an array of other smart and efficient features and you have an incredible amount of power in your hands. While carrying next to nothing.

Up to 12 hours of battery life. Power through your whole day
Thanks to compact SSD storage in MacBook Air, there's plenty of room for a big battery. Working together with the power-efficient fifth-generation Intel Core architecture, this battery can post some impressive numbers. MacBook Air gets up to 12 hours of battery life on a single charge. That gives you all-day power for surfing the web or watching iTunes movies. Put MacBook Air to sleep for more than 3 hours and it enters standby mode to conserve battery life for up to 30 days.

Fifth-generation Intel Core processors. Performance, meet endurance
MacBook Air is powered by fifth-generation Intel Core i5 processor. This ultra-efficient architecture was designed to use less power and still deliver high performance. Which means not only can you do whatever you want - you can keep doing it for longer than before. In addition, the Intel HD Gr aphics 6000 processor offers advanced performance you'll especially notice with games and other graphics-intensive tasks.

802.11ac Wi-Fi. The definition of fast
MacBook Air supports ultrafast 802.11ac Wi-Fi. When connected to an 802.11ac base station - including AirPort Extreme and AirPort Time Capsule - wireless performance is up to 3x faster than 802.11n Wi-Fi. And your Wi-Fi range improves as well. With Bluetooth technology, you can connect MacBook Air to Bluetooth-enabled devices like speakers and headphones. Even without all the wires, you're totally connected.

Fast SSD storage. Ready. Set. Done
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 (This Model has 256GB), this PCIe-based SSD storage is up to 17x faster than a traditional 5400-rpm notebook hard drive. So when you flip open MacBook Air, it's ready to go right away. Even after a month in standby mode, the screen springs to life.

Thunderbolt 2 and USB 3. Make some powerful connections
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 USB 3 devices and all your USB 2 devices as well. With just a few connections, MacBook Air transforms from an ultraportable notebook to a complete workstation.

Display, camera and mics. A sound vision

LED-backlit display. Millions of pixels. Millimeters thin
MacBook Air gives you 1440-by-900-pixel resolution on a display that measures a mere 4.86 millimeters (0.19 inch) thin. And LED backlighting makes colors bright and vibrant from edge to edge. So whether you're editing photos, perfecting a presentation or watching a movie, you're going to love what you see.

FaceTime HD camera. Stay sharp
Let your friends and family see more of you with the 720p FaceTime HD camera. Every smile looks bright, even halfway around the world. And the widescreen format means everyone can fit into the picture without having to crowd around the display.

Dual mics. They'll hear you loud and clear
The dual microphones in MacBook Air are great for when you want to be heard. If you're making a FaceTime call, for example, the mics reduce background noise from behind the notebook. And when you use Dictation, they create an adaptive audio beam that intelligently adjusts to detect your voice - instead of the noise around you.

Multi-Touch trackpad

It goes hand in hand with macOS
The Multi-Touch gestures in macOS make everything you do on MacBook Air more intuitive, direct and fun. And the spacious Multi-Touch trackpad is perfectly designed for them, whether it's a three-finger swipe to activate Mission Control or a four-finger pinch to see all your apps in Launchpad. Gesture responses are smooth and realistic. So when you're scrolling up and down a web page or swiping from one full-screen app to another, it's almost like you're touching what you're seeing.

Backlit keyboard. What you see is what you type
As incredibly compact as MacBook Air is, it still manages to fit a full-size keyboard that makes typing as natural as it is comfortable. And the keyboard is backlit, so you can type with ease in even the dimmest light. A built-in ambient light sensor detects changes in lighting conditions and adjusts the display and keyboard brightness automatically. From a seat in a sunny caf to a seat on a cross-country red-eye, you'll always have the perfect lighting for any environment.

iCloud. Your content. On all your devices
iCloud stores your content and lets you access your music, photos, calendars, contacts, documents and more from whatever device you're on. So if you take a picture with your iPhone or make changes to your meeting schedule on your iPad, iCloud makes sure everything appears on your Mac, too. And it works both ways - create a to-do list on your Mac and you can make edits to it on your iPhone.
