Do you sometimes notice your MacBook starts to run slow and will often take a long time to respond? Or you frequently hear the internal fan running at high speed, trying its best to stop your Mac from overheating and damaging its internal components. If this sounds familiar, you should fix this problem as soon as possible! But how?<\/p>\n

Why is my MacBook overheating?<\/h2>\n

Your MacBook\u2019s overheating has a lot to do with its CPU usage. If it is completing a CPU-demanding process (rendering a 4k video, for example), then the fan has to work hard to cool the MacBook\u2019s internal components. To ensure that the cooling fan works efficiently, please do not use your Mac on soft surfaces, like pillows or a carpet.<\/p>\n

Malware can consume nearly all your Mac\u2019s processing power, forcing the CPU to run at 100%, or close to it. So, remember to check your Mac thoroughly for malware.<\/p>\n

Another simple reason may be that your MacBook might be too old to handle modern-day apps. If its hardware is significantly outdated, you might need to upgrade to a new one.<\/p>\n

How to fix overheating on a MacBook<\/h2>\n

Here are some easy ways to fix the issue:<\/p>\n

Use antivirus software<\/h3>\n

As mentioned, malware can force your CPU to work extra hard. To ensure this isn\u2019t causing your overheating issue, you can use an antivirus app, such as Antivirus One<\/a><\/strong>, to run a full scan on your Mac\u2019s hard drive. Antivirus One<\/strong> detects and removes malware quickly and efficiently, preventing viruses and malware from hogging your Mac\u2019s resources and potentially damaging it.<\/p>\n

\"Antivirus<\/picture><\/p>\n

Close some browser tabs<\/h3>\n

It might come as a surprise, but tabs in Safari, Google Chrome, and any other browser consume a lot of resources on your Mac. So, when lots of tabs are open, the CPU usage will almost always be very high, thus making your Mac overheat.<\/p>\n

Put your Mac on a hard surface and in a cool room<\/h3>\n

Using your Mac in bed while resting it on a pillow or a duvet will block the air vents and prevent the fan from cooling the processor down. You should only use your MacBook on a hard surface, such as a desk.<\/p>\n

Apple recommends that while using your Mac, the ambient temperature should be between 50\u00b0F and 95\u00b0F (10\u00b0C and 35\u00b0C). If your room\u2019s a little too hot or cold, make sure to either turn on the heater or the AC.<\/p>\n

Use Activity Monitor to close processes<\/h2>\n

To check whether your Mac\u2019s CPU usage is abnormally high, you can use the built-in app, Activity Monitor. To do so, go to Finder > Go > Utilities<\/strong> and open Activity Monitor<\/strong>, which displays all the processes active on your Mac in real-time. Select the CPU tab to see each process\u2019s CPU usage, ranked from the highest to the lowest. Select the processes with high CPU usage and close them by clicking the X located at the top of the window.<\/p>\n

Restart your Mac<\/h3>\n

This will refresh the operating system and close apps and services that were running in the background taxing your Mac\u2019s processor without you even knowing about it.<\/p>\n

If after trying all the above solutions, you still can\u2019t cool your Mac down, you can try resetting the SMC, which can seem a little bit complicated, but it might just be the perfect fix. Check below for instructions.<\/p>\n

Reset the System Management Controller<\/h3>\n

The System Management Controller (SMC) is the component that controls the keyboard, fan, battery, and other important internal hardware. If you\u2019ve noticed that your Mac\u2019s fan is often running at full speed, you should consider resetting the SMC. Here\u2019s how to do it:<\/p>\n

First, you need to check whether your Mac has a T2 chip or not. To do this, please click here<\/a>.<\/p>\n
