9 Methods to Stop MacBook From Overheating
By preventing overheating, you can protect your MacBook’s internal components, maintain its performance and battery life, and ensure a comfortable user experience.
Below, I’ve shared the methods I personally use to prevent my MacBook from overheating. I’ve tried all these steps on my MacBook Air M2, 2022, but they also work on other models.
1. Clean Your MacBook
A major cause of MacBook overheating is dust and dirt clogging up its cooling system. When fans get dusty, they can’t cool the Mac effectively, leading to overheating. This can also make your MacBook’s fans noisy.
Here’s how to clean up your MacBook:
- Shut down your MacBook and unplug it from the power source.
- Use a soft brush or a can of compressed air to remove any dust or debris from the vents and ports.
- Use a lint-free cloth or a microfiber towel to wipe the exterior of your MacBook.
- Repeat this process at least once every few weeks to prevent dust buildup.
2. Use Cooling Pads and Laptop Stands
Cooling pads and laptop stands are great accessories for MacBooks. They help improve airflow and prevent overheating. I use a laptop stand for my MacBook, and it really helps keep it cool. You can also invest in a good laptop stand for long-term benefits.
Here are some tips to stop MacBook from overheating:
- Use a cooling pad or laptop stand to elevate your MacBook and improve airflow.
- Choose a cooling pad or laptop stand with built-in fans to improve airflow.
- Keep your cooling pad or laptop stand clean to prevent dust buildup and stop MacBook from overheating.
3. Identify and Close Resource-Intensive Apps
The Activity Monitor on your MacBook can show you which apps and processes are using the most resources, helping you identify what might be causing overheating. By using Activity Monitor to spot and manage these resource-intensive tasks, you can prevent overheating and protect your MacBook from potential hardware issues.
Here’s how to use Activity Monitor to close programs with high CPU usage:
- Open Activity Monitor from Finder > Applications > Utilities.
- Click the CPU tab to view each app’s percentage of CPU usage.
- Identify any applications using excessive CPU resources, and quit or close them by selecting the program and clicking the small x icon in the top bar.
You can also use MacKeeper to clear memory and free up RAM on your Mac to improve its performance. Follow these steps to use the Memory Cleaner from MacKeeper:
- Download and install MacKeeper.
- Launch MacKeeper and click Memory Cleaner.
- Click Open in the memory cleaner.
- Tap Clean Memory.
- This will perform a memory cleanup and free up occupied memory.
- Alternatively, click the x next to an app consuming excessive system resources to close it.
- Confirm by clicking Quit in the prompt window.
4. Keep Your MacBook in a Cool Place
Macs naturally produce heat while running, and if they’re in a hot environment, the internal temperature can climb too high. This excess heat can lead to slower performance, frequent crashes, and in severe cases, hardware damage.
Here are some tips to stop MacBook from overheating and keep it cool:
- Keep your MacBook away from direct sunlight.
- Keep your MacBook in a cool, well-ventilated area.
- Avoid using your MacBook on soft surfaces like beds or sofas, as they block airflow.
5. Use Safari Instead of Chrome
In Safari vs. Chrome on Mac, Safari wins because it’s Mac’s native browser developed to work seamlessly with the system. It prevents overheating on a Mac due to its optimized design for macOS. Setting Chrome as your default browser can cause your MacBook to overheat, as it’s known to be a resource-intensive app. So, it’s better to set Safari as your default browser.
Here’s how to switch to Safari:
- Click the Apple menu in the top left corner of the screen and select System Settings.
- Click Desktop & Dock in the left sidebar.
- Scroll down and look for the Default web browser option.
- Click the pop-up menu next to Default web browser and select Safari from the list of available browsers.
- Safari is now set as your default browser on Mac, and any links you click will open in Safari by default.
6. Close Extra Browser Tabs
Each open browser tab consumes CPU resources, especially if the tab is running complex scripts or multimedia content. By closing unnecessary tabs, you reduce the CPU’s workload and prevent your Mac from overheating.
Here’s how to close all unused tabs at once in Safari:
- Select your Safari window with multiple tabs open.
- Right-click the tab you want to keep and select the option Close Other Tabs from the context menu.
This will close all tabs except the one you selected.
7. Adjust Graphics Settings
MacBooks handle graphics-intensive apps, but running them for extended periods can cause your MacBook to overheat. These apps require a lot of processing power and graphics rendering, generating heat.
You can adjust graphics settings to stop MacBook from overheating by following these steps:
- Click the Apple icon in the top-left corner of your screen and select System Settings.
- Select Displays.
- Choose a lower resolution to reduce graphics usage.
- Your Mac will require less processing power for resolution and not overheat.
8. Remove Extra Login Items
Every login item (apps or services that start automatically when you log in) consumes system resources. By removing unnecessary items, you reduce the initial load on your CPU and memory during startup. This will prevent your Mac from heating up due to excessive CPU load.
Here’s how to change start-up programs on your Mac:
- Click the Apple icon and select System Settings.
- Select General and click Login Items in the right menu.
- Here, you’ll see the items that launch when you start up your Mac.
- Select the login item you want to remove and click the – button at the bottom of the list to remove the login item.
You can also use MacKeeper to manage your login items. Here’s how:
- Download MacKeeper and install it on your Mac.
- Open Login Items under Performance in MacKeeper.
- Click Start Scan.
- Select unnecessary items from the list and click Remove Selected Items.
- Tap the Remove button on the pop-up.
- It will remove your selected items from the system startup list. You can click Rescan to repeat the process.
What Else Can MacKeeper Do?
Besides uninstalling apps, freeing up RAM, and removing login items, MacKeeper can scan your Mac for viruses, delete duplicate files, and clean junk files to enhance your Mac’s overall functionality. Check out my detailed MacKeeper review to learn more about its features.
9. Update Your macOS
Apple regularly updates macOS to optimize performance and efficiency. These updates can include improvements in how the operating system manages resources, leading to less strain on the CPU and, consequently, less heat generation.
Here’s how to update your macOS on Mac:
- Click the Apple menu and select System Settings.
- In the System Settings window, click General and select Software Update.
- Here, you’ll see information about the current macOS version installed on your Mac and any available updates.
- In the Software Update settings, if an update is available, you’ll see an option to download and install it. Typically, you will find a button labeled Update Now.
- Click the Update Now button to initiate the download process.
- Once the download is complete, the macOS installer will automatically launch.
- Once the installation is complete, your Mac will restart with the latest macOS version.
