Hello, there! Given my inexperience with unscrewing things and my constant fear of messing things up, this was the very first item I successfully completed in order to extend the life of my MacBook’s hard drive. Moreover, guess what? Despite my expectations, it was not as frightening or complex as I had anticipated. It’s a really simple and basic activity that can be completed once or twice a year with no difficulty. Over time, there is normally a significant amount of dust within your MacBook, and keeping it clean may help to avoid overheating as well as keeping your Mac working quietly and efficiently. As soon as you’re through, your MacBook will be overjoyed and will forgive you for leaving it in your bed for a few (or many) hours. It’s a new beginning for the two of you! All you need is a little work space, a P5 Pentalobe screwdriver, a cleaning cloth, maybe a hair dryer (or powerful lungs, if you want to blow yourself up), and some form of (clean!) little brush to get started. Let’s get started!
This step is almost the same for each recent MacBook, with the exception of the latest Touch Bar devices, which are somewhat different (more on that below). Flip your MacBook over so that the bottom is facing up and the top is facing down. Take your P5 pentalobe screwdriver and carefully remove the screws that are located around the circumference of your MacBook Pro. Keep note of each screw and where it is supposed to go since some of them are various lengths, so keep track of everything.The bottom cover may be removed by lifting it up from the rear after all of the screws have been removed. Additionally, certain MacBook models include a handful of tiny clips that keep the lid in place from the centre. To remove the clips, gently lift up the cover from the centre.
Apple has now added a new step to the removal of the bottom cover of the MacBook Pro, starting with the Touch Bar model announced in 2016 (and includes the non-Touch Bar variants). The lid must be removed entirely with the help of the pentalobe screws, a suction cup, and a guitar pick, among other tools. This iFixit tutorial will teach you how to do this.

After that, find the cooling fan (s). Depending on your exact model, you may have more than one of them, but they are simple to identify. Just keep an eye out for the round black turbine-like objects. Given the fact that cooling fans draw in air from the surrounding region, this is most likely where the greatest dust will accumulate. For this reason, if your home is exceptionally dusty, you may have a significant amount of cleaning work ahead of you.
After that, grab your can of compressed air and begin gently blowing away dust anywhere you notice it is accumulating. Obviously, you do not want to run it at full speed all of the time since it runs the danger of destroying internal components.
Make sure that when you come to the fan, you use a finger to hold the fan in place and prevent it from spinning while you are using the compressed air. Otherwise, the fan would spin up far more quickly than it is intended to, which might cause damage to the fan motor and fan bearings over time.
Even if there is any tenacious dust, you can use some cotton swabs to loosen it up and then blow it out, but the majority of dust should be able to exit without too much difficulty if you are careful.
As soon as you’re finished, just reattach the bottom cover, being care to push the clips in the middle into place to ensure they stay in place. Replace the screw and you’ll be right as rain once again!
