Experts advise against using screen protectors on MacBook displays
Technology writers explain why adding a screen protector to a MacBook can cause more harm than good.

Potential damage to the display
Adding a protector may scatter light and reduce overall clarity on the screen. The large surface area makes it difficult to apply the film without creating air bubbles.
Laptop design differences matter
A laptop is different from a phone because it stays closed when moved around. Users are less likely to drop the device since it rests on a sturdy surface instead of being held one-handed.
Cons outweigh theoretical benefits
The disadvantages simply outweigh the benefits for this specific type of expensive electronics. Privacy features found on fancier protectors are not necessary for a device used primarily on a desk.
