If you want your MacBook to last as long as possible, you must take proper care of it. Many users make fun of this statement and say that, after all, it is a machine that is meant to serve us, not us.

This is true, of course, but on the other hand, there are certain rules and recommendations that we must follow, plain and simple unless we want to part with our Apple computer after a year of use. So let’s take a look together in this article at 6 ways that are guaranteed to make you destroy your MacBook sooner or later.

Sweaty hands

Many of us have to work on our Macs in the high temperatures of summer. Naturally, these conditions make you sweat, including on your hands. Some people are lucky enough to sweat more than average, even in months when it’s not too hot. While it might seem trivial initially, sweaty hands are bad for your MacBook, especially from a design perspective.

If you’ve owned your Mac for a few years and you see faded spots on the left and right sides of the trackpad or marks on the keys, this is what sweaty hands cause. The surface of MacBooks is anodized and aggressive sweat can destroy this special coating, leading to the aforementioned problems. So you need to keep your hands clean.

Use of poor quality chargers

If you want to ensure that your Mac’s battery loses its performance quickly, use non-original and cheap chargers, including cables. Each MacBook comes with the original charging adapter and cable, which you should use in all cases, and if you move your computer around.

Take the original charging kit with you, or get a second one. Of course, original chargers are more expensive. Still, in any case, it is a worthwhile investment that will ensure that the battery lasts longer and that the hardware is not damaged, which is essential.

Using iPhone as a webcam

If you are intrigued by the new functionality of macOS Venture and iOS 16, I recommend that you do not use this functionality with at least a mount on your MacBook display. The iPhone itself is heavy and risks irreparably damaging your MacBook. And that, at least from my point of view, is not worth it. More in my previous article.

Exposure to excessive heat

Apple computers have an optimal temperature range, specifically between 10 and 30°C. Of course, your device will work outside of this range, but you have to consider that it may not like it, and you may experience some problems. If you regularly expose your MacBook to excessive heat, the battery will be the first to take the hit.

It will start to lose its properties quickly, causing it to deteriorate, so it won’t last as long as it once did. The battery may inflate and catch fire in the worst and most extreme cases. In addition, heat is bad for other components, and if you’re working in high temperatures, expect general overheating and possible shutdown.

Use in dusty environments

MacBook is a portable computer, so you’ll be expected to carry it around. However, it’s important to operate it in places with no excessive amounts of dust particles or other clutter in the air. If you use your MacBook excessively in such an environment, there’s a risk that these contaminants will get sucked in through the vents and settle there, which is a problem in the long run.

However, some users simply have no choice. If you’re one of them, be sure to reach for a MacBook Air M1 or M2 — these machines don’t have active fan cooling so that dirt won’t be sucked into the guts.

Improper cleaning

It’s not just for hygiene reasons that you should clean your MacBook regularly. Just think of all the things you touch during the day, which simply means your keyboard won’t be the cleanest place on the planet. However, Macs need to be cleaned properly, especially their display. Specifically, you should clean it with a good quality microfiber cloth, or ideally a genuine Apple cloth, in conjunction with water.

As for the keyboard and body, you can use a cloth soaked in water, but don’t be afraid to use a disinfectant. However, never apply the products directly to the surface, i.e., the keyboard, but to the cloth.
