Tight Tolerances: Apple attributes this extreme sensitivity to what it calls "tight tolerances" in its device design. MacBook devices are designed to be as thin and light as possible, leaving very little space between the screen and the keyboard when the lid is closed. Any foreign object, even a thin camera cover or small food crumbs, can exert immense pressure on the screen, causing severe damage that may cost hundreds of dollars to repair.
