How to Prevent Mac from Heating Up – Guide

We recommend that you try the following troubleshooting recommendations:

  • Disconnect your MacBook from the power outlet and try again later.
  • Open the laptop lid and check if there is any smoke or heat coming out. If so, it means that something is wrong with the laptop.
  • Check if there is any liquid or dust on the keyboard or trackpad. If so, it means that something is wrong with the laptop.
  • Check if there are any cords connected to your MacBook and to other devices in your room. If so, it means that something is wrong with your room’s electrical wiring.
  • Try restarting your MacBook if it has been idle for a long time or if it has been used in an environment where high temperatures were present (like in a car).
  1. The software or hardware you are using is too demanding or intensive.
  2. Your battery is not holding up as well as it should be.
  3. You are using an old or unsupported operating system.
  4. You are not using the recommended cooling methods for your MacBook Pro or MacBook Air.

Avoid Chrome

Apple says that apps that are not used often can cause your processor to work overtime and affect your computer’s heat level. If you use apps on your MacBook Pro frequently, Chrome would have taken a field lap.

When your MacBook’s CPU works hard, its cooling fan kicks in to dissipate heat. To see which apps are using the most CPU resources, open Activity Monitor and click the CPU tab. In my experience, the usual suspect at or near the top of the list that uses the highest percentage of CPU is Google Chrome Helper and Google Chrome. If that also describes your experience, it might be time to switch to Safari or another browser.

Keep tabs to a reasonable minimum

Browser usage is a major issue that can affect your computer’s performance. Closing or bookmarking tabs can help reduce your workload.

Chrome Task Manager is a handy tool that shows you the CPU and memory resources each tab and extension is using. To open Chrome Task Manager, click on the triple dot button to the right of Chrome’s URL bar, click More Tools and then Task Manager.

Slow down your multitasking roller

I have a MacBook Pro that struggles when iTunes and Photos are open at the same time. So I use my iPhone to play music and open iTunes only when absolutely necessary. If your Mac struggles to juggle multiple apps, lighten its load by closing apps you’re not using instead of leaving them running in the background.

No laps, no sun

MacBooks Vent Along the Back Edge

I also find that the fan spins less frequently when my MacBook Pro is not exposed to direct sunlight. When the sun hits my kitchen table in the morning, it’s time to take my coffee and MacBook to my office. Apple recommends keeping your MacBook in a location between 50 and 95 degrees Fahrenheit (10-35 degrees Celsius).

Test your fans

If your MacBook is overheating, it may be because of something wrong with the fan. If you do this before June 2013, you’ll use Apple Hardware Test. After that date, you’ll use Apple Diagnostics.

These tools work in a similar way. With your MacBook plugged in and all external peripherals removed, restart it and hold down the D key to launch any diagnostic programs. Follow the onscreen instructions to start the test. The standard test takes just a few minutes to complete and will report any hardware issues.

I was able to complete the Apple Hardware Test by holding the D button on my early 2011 MacBook Pro, but I couldn’t get it to start. I tried this key combination if I had trouble starting the test.

Clean your Mac

If you’re having trouble getting your MacBook to start up or run smoothly, it may be time to take it in for a cleaning. You can do this yourself by removing the bottom panel and cleaning out any accumulated dust, dirt, and debris. If that doesn’t solve the problem, you can try using compressed air to remove any debris or use a lint-free cloth to clean it. Finally, make sure to clean the fan and vents on the back of your MacBook as well as the entire edge. This will help improve airflow and performance. ..

keep up to date

Apple releases new versions of macOS and apps as free updates, so there’s no reason not to stay up to date. New versions of macOS contain performance improvements and security improvements to keep your Mac running smoothly. Periodically check in to the Updates tab of the Mac App Store for updates and don’t ignore notifications for updates that are ready to install. ..
