MacBook retail Air 13inch

Product Name: MacBook retail Air 13inch
I dumbly went to reset the laptop to sell it — it has been completely erased … even erased the Mac software. The screen and everything is in perfect condition and work great! Just needs the software readded onto the computer to work— may have to take to an apple store if do not have the access to fix yourself. :/ Back of box photo shows gb and information on laptop 8gb etc Cord has also been chew retail on by my cat- however still works.
