For sale: MacBook Air 2011 13-inch. Please review the following points before purchasing: It shows signs of use, but there are no major scratches. After initializing the SSD, I reinstalled the OS (LION), but setup has not been completed. It is possible to upgrade the OS to High Sierra, but it didn't work well in my environment, so please handle it yourself after purchase. OS: LION SSD: 256GB Memory: 4GB Accessories: Power adapter
