Apple does not recommend that customers use camera covers, palm rest covers, keyboard covers, or even screen protectors on its Mac notebooks. Whether you have a MacBook Neo, a MacBook Pro, or a MacBook Air, trying to give your laptop extra protection can actually do more harm than good. If you have one of the latest MacBook Air models, you can close the lid and watch how the computer closes. Because of that tight fit, even an ultra-thin screen protector can become a problem over time if dust or debris gets trapped between the two surfaces. Likewise, putting your MacBook Air in a very tight backpack could add extra pressure that might break your display.
