You don’t want to necessarily give it wide-open throttle, since there’s the risk of damaging components. Next, take your can of compressed air and gently begin blowing out dust anywhere you see it. So if your house is particularly dusty, you might have a decent cleanup job ahead of you. This is likely where there’s the most dust buildup, since cooling fans suck in air from the surrounding area. Just look for the circular black turbine-looking things. You may have more than one, depending on your specific model, but they’re easy to spot. You probably won’t have to look that hard. Take the time to inspect everything for dust buildup. With the bottom cover out of the way, you now have access to the internal components of your MacBook. Step Two: Inspect the Inside and Locate the Fan(s) This iFixit guide shows you how to do that. In addition to the pentalobe screws, you also have to use a suction cup and a guitar pick to get the cover completely off.

Now, beginning with the Touch Bar MacBook Pro in 2016 (including the non-Touch Bar models), Apple introduced a new step to the removal of the bottom cover. Some MacBook models also have a couple of small clips that hold the cover in place from the center, but you can carefully just pry up the cover to unclip it. Once you have all the screws removed, you can lift up the bottom cover from the back. Keep track of each screw and where it goes, because some of them are different lengths. Take your P5 pentalobe screwdriver and remove the screws around the perimeter of your MacBook. Flip over your MacBook so that the bottom is face up. This step is pretty much the same for any modern MacBook, except for the newer Touch Bar models (more on that below).

Organization and Patience: You’ll want to keep track of screws and take your time with something like this.

Cotton Swabs: Great for removing or loosening up stubborn particles of dust and/or dirt.

Compressed/Canned Air: An easy way to get rid of most of the dust.

Guitar Picks: Needed if you have a 2016 MacBook or newer.

Suction Cup: Needed if you have a 2016 MacBook or newer.

If you don’t already have one, it’s best to buy a kit that includes a P5 bit.

P5 Pentalobe Screwdriver: Most MacBooks use P5 screws.

You’ll need a few things before you get started, some of which you may already have.
