MacBook Air 11-inch A1370 2011. Model number: A1370 / EMC2471 Charger included This was previously used by a family member. I confirmed that it powers on, but the battery is degraded. I've never used a MacBook, so I don't know the details. I believe it has been initialized... I'm looking for someone who is okay with the current condition. I will carefully package and ship the main unit and charger only.
