Silver MacBook Air with macOS Big Sur. - Model: MacBook Air 11-inch 128GB - OS: macOS Big Sur - Color: Silver - Keyboard: Japanese layout Thank you for viewing. This item was purchased about 12 years ago when I entered university. I used it for four years during university, and I haven't touched it much since graduating. Therefore, although there are no noticeable scratches, there are some scratches, discoloration around the keyboard (see image 5), and stains. There are no operational issues. The charger gets quite hot while charging. Also, it is considerably yellowed, so please let me know if you don't need it. I will include it if you understand.
