Description MacBook Air: Powerful, capable, durable, and enjoyable to use. With enough battery life to get you through the day. That's the difference between a notebook that's simply thin and light and one that's so much more. Flash storage helps make MacBook Air incredibly thin and light. Flash is also solid state, meaning there are no moving parts. Which makes it reliable, durable, and quiet. And it takes up much less space than a traditional hard drive - about 90 percent less, in fact. Installed Operating System: MacOS Catalina, can be reinstalled back to high Sierra for better performance Works Perfectly MagSafe Charger Included
