The current installed OS is OS X El Capitan, but I can upgrade to OS X Sierra (latest release) if requested before shipping out.
Comes with:
Laptop
Original charger
Speck snap on case for the laptop
(Unfortunately I can't find the box, but I'll be packaging this very carefully to prevent any damage during shipment)
Payment is due once the auction ends. It will be shipped out the same day when payment is sent in.
Please let me know if you have any other questions.
* Please, no international bidders.
