What is Mac’s kernel_task?

The high CPU-consuming kernel_task is an essential component of Mac’s operating system. This kernel_task keeps running in the background and regulates the overall temperature of the CPU.

Since this is a background process, whenever you power on your Mac, this system process automatically occupies the CPU. Ideally, this process only consumes a very tiny portion of the processor but things do not always turn out as they seem. The CPU usage by this background task can reach abnormally high limits due to several reasons as under:

  • Overheating mac due to charging constantly.
  • Issues with the hardware components of Mac.
  • Lots of CPU-intensive apps running in the background.
  • Hardware-related glitches.

Now that we know the probable causes of high CPU usage, let’s begin to troubleshoot the issue.

Force Quit the apps

The easiest yet most successful way of reducing the CPU usage on your Mac is to close the unwanted apps running in the background. For this, we will have to visit the Activity Monitor.

In the Activity Monitor window, switch to the Processes tab and then look for the apps consuming the CPU the most.

The idea is that when you will kill the CPU-intensive apps, your Mac will stop overheating and in turn, the kernel_task process will reduce the CPU usage.

Restart your Mac

If you do not see any reduction in the CPU usage by kernel_task, you should think about rebooting your Mac at the moment. Rebooting wipes out the background apps that are shooting Mac’s CPU usage. Besides, it will also reset the technical glitch in the Mac.

However, if you still see high CPU usage by kernel_task, it’s time to reset the System Management Controller.

Move your Mac to a cooler room

Apple has advised the Mac owners to use their machines in the optimum operating temperatures of 50° — 95°F which is 10° — 35°C. If you are in a vicinity with a high temperature than this, it will trigger the kernel_task process to begin regulating the temperature.

You can also take a few steps to reduce the CPU temperature from your end. You can use a cooling pad to bring down the temperature or shift to a room with a lower temperature. And yes, you should completely avoid using your Mac on a heat-blocking surface such as a bed or a pillow as they obstruct the Mac vents.
