This a new laptop purchased in December 2016. I recently started working remote and have been provided a laptop by my company so I do not have a need for the macbook. The laptop is in mint condition with no scratches and has been restored to factory settings. This is a fifth-generation Intel Core i5 processor with Intel HD graphics. It has the the latest 802.11ac technology and takes Wi-Fi speeds over the top. Operating System: Mac OS X 10.10, Yosemite. It includes the original power adaptor. Please contact me at 630.465.3327 if you have any questions.
