I can confirm this works on a 2020 MacBook Air (the display is unchanged from the 2018 model) and it was applied with minimal effort. A few usage tips: Turn off the air conditioner so there is less dust. Wipe the MacBook screen with Windex or a similar product that leaves streaks and lint on the screen. Align the webcam opening with the top edge of the screen. This screen protector fits almost perfectly, with about a third of a millimeter of leeway on the left and right edges if you center it perfectly. If you have air bubbles with tiny dust particles inside after application, use two pieces of tape (not included): one as a pull tape to pull away from the nearest corner, the second piece of tape is used to catch dust from the underside the protective film. Overall I am giving this product five stars because it lives up to the advertising: matte/anti-glare fit for 2020 MacBook Air. Application was simple and easy for me but YMMV.
