Apple MacBook Air, Model A1466 (Mid-2012). 13.3" screen. 1.8GHz Dual-Core Intel Core i5. 4GB RAM, 128GB SSD. Updated to macOS Catalina Version 10.15.7, the most updated software available for this model. Has been tested and works great, no issues across several hours of testing on different occasions weeks apart. Has since been wiped to factory settings. 

Device is in excellent condition. No dead pixels, no issues with trackpad or keyboard, no difficulty charging, no problems with camera. There is some light scratching along the bottom of the device, as well as some light wear to the rubber circular pads (all pictured). The fan is loud when it kicks on, but battery seems to function well when tested (and holds when not in use). The left side USB is misaligned and does not currently take in a plug, but the right USB works fine. 

There are a handful of VERY small flecks of dirt on the screen: in picture 19, they're the small white-looking dots (not the four big circles -- that's a reflection of my recessed lights overhead). They aren't actually white: they have maximum light on them in the picture so that they'd contrast with the dark screen for the photo, but they are black and unnoticeable when the screen is on, and should be able to be removed (I just didn't want to risk damaging the screen). Everything else looks great. 

Also includes charging cable, including Apple extension cord. There is some light discoloration/marking along parts of the cables (all pictured), and some scratches in the rubber of the extension cord's plug end, but both work great. 

Overall, this device is in great condition.
