How to Solve Kernel_task High CPU Usage on Mac

It can be way too annoying when your Mac’s performance drops significantly, but it gets even worse when you are unable to find the reason why it is getting this slow. You might try to stop specific processes and programs on your Mac to fix this problem, but in some cases, you will hardly see any improvement. If you are also going through the same situation and your Mac has suddenly become slow, then it is possible that kernel_task is affecting your Mac’s CPU performance.

In this article, we will teach you how to fix high CPU usage due to kernel_task on your Mac.

What is Kernel_task?

The series of low-level features that enable your Mac to work is known as Kernel_task. That’s why telling which of these features is slowing down your device can be hard.

Examining Your Sluggish Mac

You can use the Activity Monitor feature on your Mac to find out which item is causing your Mac to slow down. This feature is just like the Task Manager of a Windows-based PC.

Here’s how to access Activity Monitor on your device and find the problematic feature:

  1. First and foremost, hit the Cmd + Space keys on your keyboard at the same time.
  2. Now enter “activity” and then you will see Activity Monitor in the relevant results.
  3. Select the Activity Monitor from the result. You can also open it via Applications > Utilities. To open it conveniently every time, you can place it inside the Dock.
  4. Now click on the CPU tab from the above tabs.
  5. In the CPU tab, click on the %CPU option to see which process is using the most CPU output.
  6. The features consuming most of your CPU will now show up on the upper side of the column.

If you have not opened any program, apps, or games in the background, and you still see high CPU usage, it means something is wrong with Kernel_task processes.
