02
of 08Why Your MacBook Is Overheating in the First Place
Before we dive into the fixes, let’s understand the “why.” An overheating MacBook is usually a symptom of your computer’s processor (CPU) working overtime.
When the cooling system can’t keep up with the heat generated, your MacBook Pro or Air will start to run hot.
Several culprits can contribute to overheating. Often, it’s demanding software, like video editors, games, or even a browser like Chrome with dozens of tabs open.
Sometimes, the cause of overheating is physical, such as blocked air vents that prevent proper air circulation.
03
of 08First, Check Your Mac’s Temperature and CPU Usage
Knowledge is power, especially when diagnosing an overheating issue. You can’t fix an overheating Mac if you don’t know what’s causing it.
The first step is to play detective with a built-in macOS tool: the Activity Monitor.
To open it, go to Applications > Utilities > Activity Monitor. Here, you’ll see a list of all the processes running on your Mac.
Click on the “% CPU” tab to sort apps by how much processing power they’re using; this is a common reason to cause your mac to overheat. If you see an application or a browser tab hogging a high percentage (say, over 70-80%), you’ve likely found a major contributor to the mac overheating problem.

of 08Quick Software Fixes to Stop Mac From Overheating
Let’s start with the low-hanging fruit. These simple software adjustments can have a huge impact on your mac temperature and are easy for anyone to do.
You can often reduce overheating in just a few clicks.
Manage Your Browser Tabs
Your web browser might seem innocent, but it’s a notorious resource hog. Having too many tabs open, especially in a memory-intensive browser like Chrome, can easily cause mac overheating.
Make it a habit to close tabs you aren’t actively using. For a lighter footprint, consider switching to Safari, which is often more optimized for macOS.
Hunt Down Runaway Applications
Using the Activity Monitor we mentioned earlier, identify and quit any applications that are using an excessive amount of CPU power. Sometimes, an app can get stuck in a loop or glitch, causing it to run hot.
Simply quitting and relaunching it can often fix the problem. This is one of the most effective ways to stop your macbook from getting too hot.
05
of 08The Physical Fix: Keep Your Mac Cool
If software tweaks don’t solve the MacBook overheating issues, it’s time to look at the physical environment. Your Mac’s cooling system relies on a clear path for cool air to enter and hot air to exit.
Any obstruction can cause your mac to overheat.
Improve Air Circulation
Using your MacBook on a soft surface like a bed, pillow, or your lap is a classic mistake. These surfaces block the crucial air vents, trapping heat inside.
To prevent mac overheating, always use your MacBook on a hard, flat surface like a desk or table. This simple change ensures the parts of your macbook designed for cooling can do their job.
06
of 08Advanced Solutions for Persistent Overheating
If you’ve tried everything above and your MacBook is still getting hot, it might be time for more advanced steps. These address deeper system-level glitches or potential hardware issues.
Don’t worry, they’re still very manageable.
Reset the SMC (System Management Controller)
The System Management Controller is a chip within your MacBook that controls physical components like fans, battery, and thermal management. A glitch here can lead to fans not spinning up correctly, causing a MacBook Pro overheating problem.
To reset the SMC is a reliable way to fix many hardware-related quirks.
The process to reset the SMC varies by model (especially between Intel and Apple Silicon Macs), so you should search for the specific instructions for your machine. For many Intel-based MacBooks, it involves shutting down the Mac and then holding a specific key combination (like Shift-Control-Option) along with the power button.
This can be a magic bullet for a persistent overheating issue.
Check for Hardware Issues
If even an SMC reset doesn’t work, you might be facing a hardware issue with the fans. A failing fan won’t spin fast enough (or at all) to expel hot air, which will definitely cause overheating.
You might hear a grinding fan noise or no sound at all when the Mac is under load. At this point, it’s best to consult with Apple Support or a certified technician to fix the problem.
07
of 08How to Prevent Overheating in the Future
Fixing an overheating MacBook is great, but preventing the overheating problem from returning is even better. Adopting a few good habits can help keep your macbook cool and extend its battery life and overall lifespan.
Keep Your macOS and Apps Updated
Apple and app developers frequently release updates that include performance improvements and bug fixes. These can resolve inefficiencies that were causing your processor to work harder than necessary.
Regularly updating macOS is a key step to prevent your mac from overheating.
Be Mindful of Your Work Environment
To prevent overheating, avoid using your MacBook in direct sunlight or in a hot, stuffy room. The ambient temperature directly affects your Mac’s ability to cool itself.
Ensuring good air circulation around the device is one of the easiest ways to keep your mac cool and avoid overheating.
Use a Laptop Stand
For a long-term solution, consider a laptop stand. A stand elevates your MacBook, maximizing airflow around its entire chassis.
Some even come with built-in fans for active MacBook cooling, which can be a lifesaver if you frequently perform intensive tasks. This is a great way to prevent your macbook from overheating during long work sessions.
Frequently Asked Questions (FAQ)
How can I stop my MacBook from overheating?
To stop your MacBook from overheating, ensure proper ventilation by using it on hard surfaces and avoiding soft materials that may block vents.
