MacBook Air (11-inch, Mid 2011) Please check the specifications in the photos. In short, it's an i5, 4GB, 128GB model. A rare 11-inch model, for enthusiasts. It still has a truly beautiful design. Condition: * It's a vintage Mac. Considering that, I think it's generally in good condition. * I'll include a USB memory stick so you won't have trouble with OS updates. * Includes the box and charger. I'm selling it as a set so you won't have to buy things later on. I'm trying to make it a bargain. (If you can't install the OS and try to buy memory on Amazon, it will cost a lot.) Details: * Initialized ⇨ macOS: High Sierra installed * Battery: As shown in the photos, the cycle count is low, and it still works. * Playing YouTube videos on Chrome, it loses about 30% in 1 hour. I think it's excellent. * No noticeable scratches on the main body, just small chips and scratches as shown in the photos, which are typical for a used item. * I didn't notice any yellowing or deterioration of the LCD (dead pixels or white spots) during my use. * Charging works fine. The MagSafe charger is also in good condition with little yellowing. * Includes a USB memory stick (High Sierra) that allows offline installation. If you buy a used model of this machine, it will come with the initial OS (Lion), so you will have trouble updating the OS. Important Notes: * As this is a used sale of personal precision equipment, I do not guarantee any operation. I have checked it as much as possible through daily use as described above. It was confirmed to be working properly just before listing. * This is a listing and inspection by an amateur. I cannot respond to any discomfort caused by minor errors in the description or differences in values regarding the condition. * I think it's a "generally clean unit," so I think those who are used to buying used items will be able to purchase with confidence. * Shipping will be done with the original box placed inside a cardboard box or simple packaging. I believe there will be no problem as there are original cushions inside. * I will inform you of the password at the time of the transaction. * Please do not negotiate the price. I will ignore such requests.
