Keep dust out of your MacBook Air keyboard.

Yes, it’s a problem—especially if you have a butterfly keyboard model (2015–2019). Those are basically dust magnets with paper-thin travel. The newer Magic Keyboards (2020+) are much better, but dust still finds its way in.

Prevention is simple: don’t eat over your laptop, store it in a sleeve when not in use, and give it a quick blast of compressed air every couple weeks. Aim the straw at an angle, not straight down—you want to push dust out, not deeper in. A soft brush (like a clean makeup brush) works for crumbs stuck around the keys.

One thing I’d skip: keyboard covers. They can trap heat and leave marks on the screen when you close the lid. Not worth it.

If a key already feels sticky, try holding the laptop at a 75-degree angle and blasting compressed air while pressing the key
