Has been used for a while and has some superficial wear. Battery will last for about 3 hours. That being said it has never had a problem with the hardware or software.
Up to date with Sierra OSX. Still has a disk drive and Ethernet port, which you won't find on newer computers and are useful.
Good computer, in great working order. Lots of memory. New motherboard replaced in 2015. I still enjoy using it and find it responsive and easy to navigate.
