Thank you for viewing. MacBook Air (Mid 2012) with macOS Catalina installed. - Model: MacBook Air (Mid 2012) - OS: macOS Catalina - Processor: Intel Core i5 - Memory: 4GB - Storage: 128GB SSD - Color: Silver - Display: 13.3 inch - Resolution: 1440 x 900 It works without any problems. There is a dent on the corner from a bump. Please check the photos. Other than that, it is relatively clean, but please purchase only if you don't mind as it has been stored by a private individual. A charging cord is also included as a bonus, but it shows considerable signs of use. Please let me know if you don't need it. An orange cover is also included as a bonus. It's for the back only. Initialized.
