5 Reasons Why Your MacBook Is Overheating and How to Fix It

Updated: May 15, 2023


The boundaries of technology were pushed when Apple was founded in 1976. Since then, the company has continued producing cutting-edge technologies that have revolutionised communication, work, and gaming. The Macintosh computer was the company's flagship computer, but it gained more popularity when it released the MacBook, which is now one of the most popular laptops globally.

The MacBook is notable for its many cutting-edge features, such as its sleek design, lightweight construction, and long battery life, as well as its powerful hardware, including Intel Core processors, up to 16GB of RAM, and high-resolution Retina displays. However, the MacBook is not flawless because, like any other technology, it can still experience problems, mainly overheating. When this happens, it can impede the user's productivity and experience and damage the unit.

For this reason, one must know what causes MacBooks to overheat and what can be done. These include:

#1 - Malware

Malware is one of the leading causes of overheating in MacBooks. Malware can be found in downloads, emails, and other sources and can cause the CPU to work harder than it should. As a result, the laptop will overheat and shut down unexpectedly. The best way to avoid malware is to be wary of downloads and emails and keep the MacBook’s antivirus software up to date.

#2 - Blocked or Clogged Fans

The fans in a MacBook are responsible for cooling down the laptop and keeping it from overheating. If the fans become blocked or clogged with dust, hair, or other debris, they will not be able to do their job correctly, and the laptop will overheat.

#3 - High Ambient Temperature

The ambient temperature of the room where the laptop is located can also affect its performance. If the room is too hot, the laptop will be unable to cool itself properly, and it may overheat. The best way to avoid this is by keeping the laptop in a cool, well-ventilated area.

#3 - Extreme Temperatures

MacBooks are specifically designed to work with various temperature limits. However, too much heat can harm your computer. Apple suggests that users should keep their Macs in an environment where temperatures are between 50 and 95 degrees Fahrenheit (10 and 35 Celsius). Storing the computer in direct sunlight may be hazardous and shorten its lifespan.

#4 - Too Much CPU Stress

When your Mac runs multiple applications, its processor cores must work harder to do more tasks. This can cause the temperature inside your Mac to rise, leading to slow performance and even potential overheating. If your Mac is slowing down when using several programs at once, it is probably using too much of its processing power to manage all tasks. When this happens, it struggles to keep up, resulting in overheating.

#5 - Frozen or Unresponsive Apps

At times, applications can be slow to respond or freeze completely. This can cause the familiar spinning wheels to show up on your Mac. Even if an app isn't running correctly, it still uses your Mac's memory. If your Mac is having trouble with a slow or unresponsive app, it will use up lots of its CPU resources to try to fix it, which can cause the processor to heat up.

What Can You Do?

An overheating MacBook may be problematic, but you can try to fix it with the following methods:

Monitor Your CPU Usage

The first step is to monitor your CPU usage. You can do this by opening the Activity Monitor in the Utilities folder in Applications. This will show you the number of CPU resources each application is using. If you find one app is using an unusually high amount of resources, you can try to force quit it. You can also check the temperature of your Mac by going to the System Information app.

Regularly Clean Your Unit

Regularly cleaning your Mac can help prevent it from overheating. Start by using a can of compressed air to blow away any dust that may be blocking the vents. You can also use a vacuum cleaner with a brush attachment to remove any dust buildup.

Close Unused Browser Tabs and Apps

Having a lot of open browser tabs and apps can put a strain on your Mac's CPU and cause it to overheat. If you're not using them, close them. This will help free up resources and reduce the workload on your Mac.

Get It Checked by a Professional

If all else fails, you can take your Mac to a professional. A technician can inspect your Mac and diagnose any potential issues. They can then recommend and carry out any repairs or replacements necessary to get your Mac running smoothly again.


A MacBook may be a powerful computer, but it can experience overheating issues like any other device. You can try to fix it yourself, but you can also bring it to a professional for better results. All that matters is getting it checked and repaired as soon as possible so you can continue enjoying your Mac without further problems.
