Pretty much what it says in the title. I bought a new MacBook Pro for work, so I don't need the Air anymore. Otherwise, it's in great shape-- Same specs as the upgraded 2016 version. It cost 9000RMB new. It's running OSX Yosemite at the moment, but the upgrade to El Capitan is free-- I'll do it for you if you want. I'm leaving Beijing next Monday though, so I'm hoping to find a new home for it by then. Contact me today :)
