What Could Be Causing My Macbook to Overheat?

If your Macbook is overheating frequently, the problem could be due to several different causes. Some of these include Google Chrome, too many browser tabs open at the same time, multitasking, and external heat sources. Try one of these methods to resolve the overheating issue. Once you’ve tried these methods, check whether they work. If the overheating problem still persists, try another method.

Google Chrome

If your MacBook is overheating, it could be due to Google Chrome. This web browser uses a lot of CPU resources, and because of that, it can cause your MacBook to run too hot. While your Mac has fans to keep the machine cool, Chrome’s high CPU load is a contributing factor to overheating. You should try to switch to another browser if Chrome is causing your MacBook to overheat.

To identify the source of your overheating issue, open Activity Monitor. This is a simple way to see which programs are causing your computer to run hotter than usual. This tool also shows which apps are using the most resources, which is important for your Mac. Once you’ve found out which apps are the culprits, you can remove them from your computer and stop your Mac from getting too hot.

Alternatively, you can try removing Chrome altogether. The Chrome Helper process is one of the most common causes of overheating on Macs, so it’s best to delete it if you’re concerned about the impact on your system’s performance. However, it’s not as simple as simply dragging the Chrome icon to the Trash. You’ll need to manually type in /Library to find the application.

Too many browser tabs

The main culprit behind the overheating of your Mac is having a high number of browser tabs. Opening a large number of tabs is a resource-intensive activity. As a result, if your system starts to feel hot, you should close non-essential tabs. A simple fix is to close all browser tabs and restart your computer. This will clear up the system’s memory and restart any processes that are running.

If you have more than 12 open, you are causing your Macbook to overheat. To solve this, try closing some of the tabs that you do not use. Another solution is to limit the number of browser tabs you open. This way, your Mac will be able to cool down.

The second method is to minimize the amount of time spent on rogue processes. Generally, these are resource-heavy processes, such as rogue browser tabs. If you find that one particular website is taking up a lot of resources, close it immediately. Alternatively, you can also use an app like Tab Finder to control your browser tabs. The Finder will display your open tabs in a single list. This makes it easier to find pages quickly and close energy-hogging websites.


If you’ve recently noticed that your Macbook is overheating, you’re not alone. While multitasking boosts your productivity, it can also raise the CPU’s temperature. This is because the more programs you have open, the more your computer will be working at once, and the higher the CPU temperature will get. Keeping your computer clean is crucial to avoiding overheating, so limit the number of applications you’re running and use the most essential ones.

To improve CPU performance, close the programs that are consuming the most CPU. This includes Chrome and Safari. Keeping a maximum of 12 open is recommended, but you can also try closing applications when you’re experiencing overheating. Also, shut down any apps that aren’t essential, as they could be causing your Macbook to overheat. This way, you can give your CPU a rest.

Another way to fix the overheating problem is to reactivate the system management controller (SMC). This is the tiny computer chip inside your Mac that controls a variety of parts and settings. If you’re running a lot of apps and programs, you may want to reactivate the SMC, which will help cool your Mac. You don’t need to be an expert to do this, though.

External heat sources

When you’re using your MacBook, keep in mind that it is susceptible to overheating if it’s placed near a window or other heat-generating device. Avoid placing your Mac on a soft surface, such as your lap, to allow it to cool off. It is also important to avoid placing it in direct sunlight. Using a laptop stand is also a good idea, since it elevates the laptop off the desk and lets the hot air escape.

You should also be aware of the age of your Mac, as an older model might require a more powerful cooling fan. If your Macbook is already too old, it may be time to consider buying a new model. It is also likely that you have a lot of applications installed, some of which are CPU-intensive. When the computer is too hot, it may shut down on its own, which could mean lost data.

There are several reasons why your Macbook might overheat. While MacBooks are designed to be cool, they can get hot if they are exposed to the elements. The more heat your laptop is exposed to, the higher its chance of overheating. It can also be due to a dust problem inside the case, which interferes with the cooling fans and prevents the MacBook from cooling properly.

The first problem is overheating caused by the GPU. External displays put a lot of strain on your laptop’s graphics card, which can result in overheating. This problem is a common cause of Macbook overheating. The GPU produces a great deal of heat, which forces your Mac to run at higher fan speeds to cope with the workload. If your Macbook continues to overheat, try switching to a cooler room to work on your work.

Overheating can also damage the hardware inside of your computer. Some of the symptoms of overheating include computer slowdown and freezing. In extreme cases, your Macbook will automatically shut down if its temperature gets too high. This can protect the hardware, but it can also cause data loss. So, make sure you have all the necessary components. If you suspect an overheating problem, contact Apple for assistance.

Blocked vents

If your MacBook is overheating, one of the common causes could be blocked vents. These slots prevent the flow of cool air and trap hot air inside. To make sure your MacBook has free air flow, prop it up on a flat surface. Lastly, if the vents are blocked, update your software. Outdated software can contain bugs and security issues, and viruses can run intense background processes that can also cause your MacBook to overheat.

You can check if the air vents in your MacBook have become blocked. These vents are located under the screen hinge and along the underside edges. If you rest your MacBook on a soft surface, it could block the air vents and cause your Mac to overheat. When you are doing a heavy workload, the air flow will be blocked and your Mac will begin to overheat. Try resting your MacBook on a hard surface and leave room behind the screen for air to flow.

Out-of-date apps and OS

There are a number of reasons why your MacBook could be overheating. Running out-of-date apps and OS could be one of them. The offending software should be removed from your system, and you should also check the website for updates to the app. It may also be necessary to shut down the application for a while to let Big Sur integrate the data. However, if you have no other options, your best bet would be to take your MacBook to an Apple store for a repair.

Keeping dozens of programs running in the background will slow down a MacBook with 4GB of RAM, which can lead to overheating. To get rid of the apps that aren’t in use, force-quit them by tapping the app’s icon and selecting the “quit” option from the floating menu. Quitting an app will free up system memory and reduce the overall CPU and memory usage. Mac OS allows users to install apps from multiple sources, including the App Store and the Web. Activity Monitor will help identify incompatible applications and let you uninstall them.

Resource-intensive apps

You may be experiencing overheating issues on your Macbook because your computer is running too many resource-intensive applications. These apps require more system resources than they need to perform. Some are poorly developed and could drain the battery and CPU. Force Quitting such apps will help restore normal CPU usage. Dropbox and Google Drive Sync are two such applications that can be the cause of overheating issues. To find out what apps are consuming the most resources, use the Activity Monitor utility to see what processes are running on your Mac.

You should also close runaway applications. These programs are persistent and may not close properly. They may keep on running even after you quit them. They could even be running in the background and making your Macbook overheat. To fix this issue, you need to force-quit those apps and check the temperature of your Macbook. Finally, make sure to enable the Energy Saving Mode, which automatically turns off unneeded applications and elevates battery performance.
