MacBooks are powerful devices, but their slim chassis can often lead to overheating issues.
There are some ways to mitigate this from a hardware perspective, but there’s also some cleaning up you can do in regards to files and storage as well.
Here are seven things you can do to stop your MacBook from over-heating:
1 – Place it on a hard, flat surface
One very common cause of an overheating MacBook is a lack of airflow.
Laying the device on a quilt, bedspread or tablecloth can easily block the fans and prevent the free flow of air over the components inside the case, resulting in excessive heat build-up.
A great way to increase airflow is by resting the machine on an angled laptop stand or some other hard, flat surface.
2 – Don’t leave it sitting in direct sunlight
Allowing your MacBook to sit in direct sunlight can also cause the machine to over-heat, especially if it’s inside a hot car or small room.
Always remember this: When it comes to keeping any electronic item cool, shade is a powerful ally.
3 – Keep it free of dust and debris
Another cause of excessive heat build-up is dust and debris getting inside the device and covering the internal components.
If your MacBook can be easily opened up (most can’t, but some can), then it’s a good idea to do this and blow away the dust from the inside.
If your MacBook cannot be easily opened up, take a can of compressed air and blow it into all the vents. That will remove at least some of the dust that’s currently lodged inside the case.
If you suspect that dust is completely blocking the flow of air I recommend that you take it to a shop to have it professionally cleaned.
4 – Check the fans
It’s also important to periodically check the fans to make sure they are working properly.
Hold down the D key while your MacBook is booting up and perform a hardware scan, then check to see if the scan reported any errors.
Any type of “PPF” error indicates an issue with cooling. If you see any PPF errors that could indicate there’s an issue with the fans.
If so, I recommend having the machine checked out by a computer repair center.
5 – Use the Activity Monitor
Now we move away from hardware and onto problems that are more difficult to spot.
One possible reason why your MacBook is overheating could be that it’s simply working too hard.
If you type Activity Monitor into SpotLight search you’ll be presented with all the processes that are currently running.
Check to see if the CPU and/or memory are being overworked at near full capacity (in particular, the CPU).
If they are, try closing down all unnecessary processes and see if that helps.
Also, try closing any open browser tabs that are no longer needed.
6 – Keep its software updated
A device with software that isn’t up to date can experience all sorts of seemingly random issues.
In addition to overheating and random glitches, not keeping your MacBook fully up to date is also a serious security issue.
Head over to System Preferences and select Software Updates. If there’s one or more updates pending, install them as ASAP.
7 – Keep it free of malware
Finally, malware can play a big role in overheating any type of computer, and that includes MacBooks.
Malicious, malware-laden programs from unverified third-parties can bloat your machine and pose a serious security risk.
What’s more, they can also max out your device’s resources by introducing a lot of new running processes.
Bottom line: Excessive heat build-up is a primary cause of both system instability and premature component failure. The steps above can help cool your MacBook down and hopefully make it last a lot longer.
