Macbook Air A1369 13″ Mid 2011 1.7 GHz Intel Core i5 4 GB Mac OS X Lion 10.7.5. Excellent physical condition. No cracks or large scratches. Great working condition. Battery holds a charge for about 6 hours of use. Comes with charger. Wife bought me a Surface Pro and I’m going to give it a try…thus parting with one of my Macs.
