Apple Magic Keyboard A1644 US layout This is the Lightning port model. It does not have a touch bar or lock key. Operation has been confirmed to be problem-free. I used it while carrying it in a case, but I have stored it for the past two years. There are no major scratches, but there are some slight scuffs on the ESC and F1 keys, and many faint scratches on the back. As a bonus, I will include a carrying cover case.
