It’s natural for a MacBook Pro, or any Mac for that matter, to become warm during normal use. But, if your MacBook is running very hot, it’s probably not okay.
There are many possible reasons for such an issue. In this article, I’m going to show you some common causes for a Mac overheating. More importantly, I’ll also share with you practical solutions on how to fix a Mac overheating issue.
I’ve been using an old MacBook Pro and have experienced this problem many times. Hopefully, you’ll be able to overcome the overheating problem by applying some of the techniques listed below.
But First, Why Does Mac Overheating Matter?

Nobody is comfortable working on an overly heated computer. It’s a psychological thing: We tend to be worried and panic when it happens. In reality, the main consequence is that your hardware (CPU, hard drive, etc.) can get damaged when exposed to constant overheating. Typical symptoms of this include slowdown, freezing, and other performance issues.
Even worse, your MacBook could shut down automatically if the temperature is really high. This can be both a good thing and a bad thing. The good thing is that it protects your hardware from potential damage. The bad thing is that it can cause data loss. If this does happen to you, see if you can use a free data recovery tool to rescue your lost files.
How to Know Whether Your MacBook is Overheating
Frankly, there is no definitive way to know if your MacBook is overheating. The best way is to trust your instincts. When your Mac warms up to a point that makes you uncomfortable, it’s probably overheating.
Another way to quickly validate your judgment is by looking up the CleanMyMac Menu. You’ll know if it shows a “High disk temperature” warning. By the way, CleanMyMac is a fantastic Mac app that allows you to free up memory, remove unused apps, disable unnecessary login items, plugins, etc. which could help ease overheating issues and improve the overall performance of your Mac. See my CleanMyMac 3 review.

You might have been told to use a third-party app such as iStat or smcFanControl to monitor your Mac system stats, CPU temperature, or manage fan speed. Personally, I think that’s not a good idea for two reasons. First, they may not be accurate as you think. Here’s what Apple officially said in a support ticket:
“…these utilities are not measuring the external case temperature. The actual case temperature is much lower. Never use third-party applications to diagnose possible hardware issues.”
Secondly, fan speed control software actually has the potential to damage your MacBook. Because your Mac knows how to adjust the fan speed on its own when needed, manually overriding the speed setting could cause problems.
MacBook Pro Overheating: 10 Causes & Fixes
Please note: the solutions below apply to a Mac that is still operational when it heats up. If your MacBook shuts down itself due to overheating and won’t turn on, wait for a couple of minutes until it cools off and then restart the machine.
1. Your Mac’s Got Malware
Yes, Macs can get spyware and malware. Although macOS has integrated security protection against malware, it isn’t perfect. Plenty of junk crapware and phishing scam software targets Mac users by bundling useless apps or redirecting you to fake websites. Apple names a few here. While it’s unlikely they cause serious system issues, they will tax your system resources, which can lead to overheating.
How to Fix It: Remove Malware.
Unfortunately, this isn’t as easy as it sounds because it’s unrealistic to manually review each app and file you’ve stored on your MacBook Pro. The best option is to use Mac antivirus software like Bitdefender Antivirus for Mac.
2. Runaway Apps
Runaway apps, in other words, third-party apps that demand more system resources (especially CPUs) than they should. These apps are either poorly developed or caught in a loop, which can drain battery power and CPU resources. When that happens, it’s just a matter of time before your MacBook starts overheating.
How to Fix It: Pinpoint the “Culprit” via Activity Monitor.
Activity Monitor is a built-in utility on macOS that shows the processes that are running on a Mac so users can get an idea about how they affect a Mac’s activity and performance. Click here for more info. You can open the utility via Applications > Utilities > Activity Monitor, or do a quick Spotlight search to launch the app.
Here’s how it works. To figure out what is to blame for the increase in your MacBook Pro’s temperature, simply click the CPU column, which will sort all the apps and processes. Now pay attention to the percentage. If an app is using close to 80% of the CPU, it’s for sure the culprit. Feel free to double-click on it and hit “Quit.” If the app becomes unresponsive, try Force Quit.
3. Softer Surfaces
How often do you use your Mac laptop on a pillow or on your bed? What’s comfortable for you may not be wise for your MacBook. It’s a bad idea to put your Mac on a softer surface like that, as there will be inadequate air circulation under and around the computer. Even worse, because the fabric essentially absorbs the heat, it will make your Mac even hotter.
How to Fix It: Adjust Your Computer Habits.
Remember, sometimes the best solution is also the easiest. Place your Mac on a stable work surface. The four rubber feet on the bottom will ensure there is enough air circulation to dissipate the heat your Mac generates. You may also want to get a laptop stand (recommendation: Rain Design mStand Laptop Stand, or this X-stand from Steklo) to elevate your MacBook and cool it off better. Check the “Pro Tips” section below for more tips.
4. Dust and Dirt
Similar to softer surfaces, dust and dirt in your Mac — especially in the fans — will make it warmer. This is because Macs rely on vents to dissipate heat. If the vents of your MacBook are filled with a lot of stuff, it’s bad for air circulation. Don’t know where the vents are? On older MacBook Pros, they’re located in the hinge area right under your display and above the keyboard. The Retina MacBook Pro also has vents on the underside.
How to Fix It: Clean Fans and Vents.
First, you can use a little brush to remove dust and dirt. You can also try compressed air (recommendation: EasyGo CompuCleaner), but be careful as it might damage your Macbook’s components. Be sure the compressed air doesn’t spit out any water. If you have time and the right tools, consider opening it up and cleaning internal components like fans and CPUs. This video shows how:
5. Webpages with Flash Ads
How many times have you visited news/magazine websites like NYTimes, MacWorld, CNET, etc., and noticed your MacBook Pro fans run faster almost instantly? I experience this all the time. Don’t get me wrong; the content on these sites are great. But one thing that really annoys me is that pages on these websites tend to contain lots of flash ads and video content. They also auto play, which uses up more system resources than you might think.
How to Fix It: Block Flash Ads.
Adblock Plus is an amazing plugin that works with all major web browsers including Safari, Chrome, Firefox and more. Once you add it, it automatically blocks web ads from displaying. Another perk is that it helps speed up slow Internet on your Mac. Unfortunately, by the time I wrote this guide, I noticed some big news sites learned this trick and blocked their plugin, asking visitors to remove it in order to view their content…ouch!
6. SMC Needs to be Reset
SMC, short for System Management Controller, is a chip in your Mac that runs many physical parts of the machine including its cooling fans. Typically, an SMC reset helps resolve hardware-related issues, and is harmless. See this article for more indicators that your SMC might need to be reset.
How to Fix It: Reset SMC on MacBook Pro.
It’s quite easy and it takes less than a minute. First, shut down your MacBook and plug in the power adapter, which puts your Mac in charge mode. Then hold Shift + Control + Option on your keyboard and press the power button at the same time. After a few seconds, release the keys and turn on your Mac. If you want a video tutorial, check this out:
7. Spotlight Indexing
Spotlight is a convenient feature that allows you to quickly search all the files on your Mac. When you migrate larger files, or your MacBook gets upgraded to a newer OS X (for example, macOS Sierra), it might take a while for Spotlight to index content on the hard drive. This might cause your MacBook Pro to become hotter due to high CPU usage. How do you know if Spotlight is under index process? This thread has more.
How to Fix It: Wait Until Indexing Completes
Unfortunately, there is no way to stop Spotlight indexing process once it starts. Depending on your hard drive usage and other factors, it may take up to several hours, so be patient. By the way, if you have folders that contain sensitive data and you don’t want Mac to index them, you can prevent Spotlight from doing so. Learn how from this Apple tip.
8. Fan Control Software
As I said above, using fan control software to change the speed of your MacBook’s cooling fan is a bad idea. Apple Macs know how to adjust the fan speed automatically. Manually controlling the fan speed could cause extra issues, even damage your Mac, if done inappropriately.
How to fix it: Uninstall Fan Speed Software/Apps.
Removing apps on a Mac is usually very easy. Just drag and drop the app to Trash and empty the Trash. In rare cases, you may need to manually clean up the associated files. If you have some apps to remove, you can also use CleanMyMac, as the Uninstaller feature allows you to do so in batch.
9. Fake MacBook Charger
A normal charger for a MacBook Pro includes three main parts: AC power cord, MagSafe Power Adapter, and MagSafe connector. It’s always good practice to use the original ones that came with your Mac. If you bought one online, it could be fake and might not work well with your MacBook Pro, thereby causing overheating problem and other issues.
How to Fix It: Shop from the Apple Online Store or Local Retailers.
It’s often not so easy to spot a fake MacBook charger, but this YouTube video shares a few awesome tips. Check it out. Also, try to avoid shopping from online marketplaces, other than the official store, for Apple components. Don’t be lured in by lower prices. I can’t stress this enough.
10. Bad Computer Habits
Every computer has its own limit. You should know what your MacBook Pro is and isn’t capable of. For example, if you are holding a 2010 model MacBook Pro with 2GB RAM and a spinning hard disk drive, chances are it won’t be powerful enough to deal with too many processes at the same time. If you run photo/video editing software as well as other apps simultaneously, it won’t take long for your Mac to heat up.
How to Fix It: Know your Mac and Treat It Nicely.
First of all, check Apple logo > About This Mac > System Report to get an idea of your computer’s hardware configuration, especially Memory, Storage, and Graphics (see the screenshot below). Try not to run too many apps unless you have to. Turn off fancy animations that may tax precious system resources. Restart more often, and let your Mac sleep for a while as you do.
Pro Tips to Prevent MacBook Pro from Running Hot
- Avoid using your MacBook on a bed, fabric surface, or on your lap. Instead, always try to place it on a hard surface like wood or glass made desk. This is good for your computer as well as your health (source).
- Check your MacBook vents and clean your Mac on a regular basis. Make sure there’s no dirt or dust stuffing up the keyboard and vents. If you have time, open the hard case and clean the inside fans and heatsinks. iFixit has lots of great guides.
- Get a cooling pad for your MacBook Pro (like this portable ultra-slim cooler from TeckNet) if you use it mostly at home or at work. These laptop pads usually have built-in fans to help improve airflow and reduce the heat generated on your Mac.
- Consider elevating your MacBook with a laptop stand (check out Rain Design mStand). Since the rubber feet on a MacBook Pro is very thin, it might take longer for the heat to go away. A laptop stand will raise your Mac off the desk surface so that heat can escape more efficiently.
- Try not to run multiple apps at once, especially those that tend to consume more system resources than others — for example, photo/video editing programs, project management tools, etc.
- Have good web surfing habits. These days it’s hard to not visit news websites or magazine sites to access information. However, it’s a bad habit to load tons of web pages with flash ads, only to find your MacBook Pro fans run loudly instantly.
- Always download software and apps from their official websites or the App Store. This is important because many third-party download sites bundle crapware or malware into the programs you want to get, and they run quietly in the background without you knowing.
I hope you find this troubleshooting guide helpful. For Apple fans, MacBooks are like our working partners. Overheating issues aren’t good for your computer, surely you’re not happy about them. Fortunately, the problem doesn’t occur for no reason. I’ve shown you then of those above, and their respective fixes. It’s unrealistic that you’ll implement all these solutions, and it’s very unlikely you’ll have to do so. However, they should give you some clues about what might be causing your MacBook Pro to run hot. Let me know if you have any questions by leaving a comment below!
