5 Things You Should Do When Your Mac Overheats

Whether it is your new Mac or an old one, at times, the device can overheat. And when this happens, you have no other option but to employ ways in which you can stop your Mac from overheating. This is because if you don’t stop at an initial stage, the temperature can get so high that it might damage your Mac, causing hardware issues and, in some cases, loss of data.

The damage can be so high that your Mac may stop working completely. So, while using your Mac, you should be aware of its temperature, and if you find it going too high, pause all your work and do all that you can do to stop it from heating more. Below listed are the quick ways that you can try for your Mac to stop overheating further. Have a look!

#1. Test Activity Monitor

On your Mac, you should check the Activity Monitor to find resource-consuming applications. Apps that use comparatively more power and generate heat, causing your Mac to overheat by overburdening your Mac’s processors.

Once found, you should close such applications as many times; these even stop working or responding, and even after many tries, the apps do not open properly. To find out and close apps that consume more energy, you should execute the following steps on your Mac:

  • Navigate to Finder > Applications > Utilities
  • Open Mac’s Activity Monitor
  • Go to the CPU tab
  • Press the Stop button to close the apps having a high percentage in the % CPU column

Disabling resource-hungry apps is one of the tricks and ideas to speed up the computer and help it reclaim memory for faster performance. 

#2. Handle Mac Graphics Settings

Most Mac computers have two types of graphics cards: a more powerful graphics card and a less powerful graphics card. The graphics card that is more powerful needs more resources in comparison to the one that is less powerful. Therefore, the former causes more overheating, due to which the battery drains faster. 

Switch between the two types of graphics cards to prevent overheating and excessive battery drainage. For automatic switching between the two modes, you can execute the following steps:

  • Navigate to Mac’s System Preferences
  • Choose the Battery section
  • From the Battery section, enable Automatic graphics switching
  • With this Graphics Card setting enabled, your Mac will choose the less power-consuming graphics card automatically

#3. Close Extra Web Browser Tabs

There is a high chance of your Mac getting overheated when you perform an extensive search online, thereby opening too many browser tabs. These several open tabs can slow down your Mac significantly and burden the fans to work harder as it tries to prevent overheating.

Therefore, if you already performed a search on your browser and got search results on too many tabs, quickly check all of them and close the ones that are not required or needed. Try keeping the number of open tabs to a minimum, if possible. Of course, it should not affect your ongoing work.

Another way in which you can avoid the consumption of your Mac resource or power is by using the Safari web browser. That’s because, being in-built in your Mac, it is resource-friendly and less likely to overheat your Mac. In addition, Safari also has a private (incognito) browsing mode avoiding the need for any other web browser.

On the other hand, if you use third-party web browsers such as Mozilla Firefox, Opera, and Google Chrome, you are more likely to overheat your Mac. The reason is that these browsers consume more system resources in comparison to Safari.

#4. Keep Computer Updated

It seems irrelevant that keeping your Mac updated resolves overheating issues. Nonetheless, updating the macOS to the latest version fixes all software defects and helps run your Mac smoothly. To update the macOS, execute the following steps:

  • On your Mac system, open System Preferences
  • Navigate to the Software Updates page
  • Check if there is any update available
  • If yes, click on the Update Now button

#5. Reset System Management Controller (SMC)

The System Management Controller (SMC) in your Mac computer is a chip that controls many several physical components, including the fan. At times, on resetting the SMC, the heating issue gets fixed. 

The best part of resetting the SMC is that it is fully safe and secure without causing any harm to your Mac. To reset the SMC on your Mac, you are required to execute the following steps:

  • Shut down your Mac computer
  • Press and hold the keys Shift + Option + Control + Power from your Mac’s keyboard for 10 seconds
  • Switch on your MacBook again


With these five methods, you can fix the overheating issue of your Mac computer. So, if you find that your computer is overheating, try the tips mentioned in this article, and you should see improvements.
