Late 2010 Apple MacBook Air 11 Inch A1370 - 4GB RAM 128GB SSD - Bad Thunderbolt. Device works perfectly apart from having a bad DisplayPort Connecter. This device has a brand new iFixit battery installed. Very good cosmetic condition. After a clean it will look almost perfect. Some residue on the bottom case from a previous sticker. Fully tested, no issues found except for the bad Thunderbolt port.
