How to Fix Your Mac’s “kernel_task” High CPU Usage Bug?

Maybe the most simple answer to some OS problems is upgrading macOS to the new update.

Simply boot Machine Settings, press Upgrade Program and execute some excellent device upgrades for Apple.

The kernel-tasking process is Adobe Flash as another common cause of high CPU use.

Activity monitor can indicate that a kernel task machine operation requires a large percentage of the CPU, so you can feel a more fan frequency during this period.

Kernel task is designed to respond to conditions which cause your CPU to get too hot even if your Mac doesn’t feel hot. 

In this article, we will discuss the important aspects of kernel_task and how to fix it conveniently.

The topics  we will be discussing in this article are,

  • Kernel_task
  • A slow mac
  • Why kernel_task
  • Solutions to stop kernel_task
  • Updating to latest versions
  • What causes high kernel_task CPU usage?
  • What is another alternative for high CPU usage?

Kernel_Task

How to find cause of high kernel_task cpu usage? - Ask Different

You may have another issue with your hands if you consider kernel tasks utilizing a lot of the CPU or the memory if you are not doing a lot of things.

This usually applies to kernel extensions, recognized as “kexts” by macOS from third parties.

A defective key could lead to unnecessary machine resources being used by the kernel task. One of the kernel system process functions is to help control the CPUs temperature.

A Controller might indicate that a kernel task system process uses a significant percentage of your CPU, and you might notice more fan activity during that time. 

Moreover, you can say that it is another name for several low functions that are working in your computer to perform smoothly, but if there is some trouble in any of them that means your device is in near to decade or cannot perform with efficiency.

Here are a few things which will help you notice such an issue!

A Slow Mac

How to Fix a Slow or Unresponsive Mac

One of the signs to detect the high CPU usage is that your mac will be running slowly or generating a lot of heat. In that scenario open an activity monitor and look for the issue.

Activity monitor is one of the useful tools for managing resources equivalent to windows task manager. You can open the task manager with the help of a spotlight.

All you need to do is press Command + space and start typing Activity and it will pop up on your screen. You can also access it by Applications > utilities.

For quick access just add it to the dock. One of the other reasons for a slow mac can be evident on the CPU tab. Simply select the %CPU column to organize the running processor.

In this way, you’ll be able to find out what is consuming the most of the CPU’s processing power.

Anything consuming the more power will be at the top of the list which will help you to solve the issue. Strong use of CPUs is normally a concern even when you don’t anticipate it.

It’s fair to expect your machine to check resources when you run a game, view a video on your monitor or edit your file.

There’s something usually wrong when there’s more than its fair share in a single MAC or Safari window.

Why kernel_Task?

So you must be wondering why the culprit is kernerl_task? Well, that’s because it is part of macOS and a number of processors fall under it.

You can easily kill the process by clicking X at the top left corner of the screen except for the kernel_task itself.

macOS is responsible for all the tasks running in the background. Such as sending and receiving data, writing and reading the data and disks for spotlight search etc.

And as a matter of fact, such processes consume a lot of your RAM’s memory but that’s not something to worry about. High CPU can easily drag your whole system down and might result in a system crash.

Solutions To Stop Kernal_Task

Well in such cases it is necessary to stop kernel_task from affecting negatively to the performance of your device.

A simple restart can help your mac to start working again calmly but that too does not work in many other cases but it’s a short term fixing result.

In addition to this, you can also restart your SMC (System management controller). It’s an effective alternative to fix any existing issue with your Mac. 

In addition to this instruction for SMC depends upon the model of your Mac that you’re using.

When SMC is giving a good response that means your Mac is in good condition. It can actually fix many issues.

Updating To Latest Versions

By updating to the latest versions of Mac can fix many OS related issues. 

  • Open system preferences 
  • Select software update and run any of the amazing outstanding apple’s software updates

And as a matter of fact, as mentioned above Adobe Flash is the major reason for high CPU usage.

Instead of using Adobe Flash, you use Google chrome for any purpose that makes you use the Adobe Flash as it is a very good alternative as compared to AF.

here comes a question to your mind that is it safe to remove it? yes absolutely safe because google chrome provides Flash (albeit optionally).

Just simply run the adobe flash player install manager and select uninstall and remove it safely.

What Causes High kernel_Task CPU Usage?

This usually applies to kernel extensions, recognized as “kexts” by macOS from third parties.

How to Fix Your Mac's "kernel_task" High CPU Usage Bug

A defective key could lead to unnecessary machine resources being used by the kernel task.

One of the kernel system process functions is to help control the CPU ‘s temperature.

A Controller might indicate that a kernel task system process uses a significant percentage of your CPU, and you might notice more fan activity during that time. 

One of the initiatives to prevent kernel_task issues is to restart your machine in a safe mode to check the third party texts.

Just follow the steps mentioned below to do it smoothly. Follow the steps to do it accurately

  • Restart the machine and press shift key as it boots.
  • Safe mode required kernel extensions to work efficiently so there is no problem handling third party text issues.
  • To run this smoothly make sure that you restart the system and launch terminal then run the next command to see the loaded kernel extensions. All the extensions from apple will appear as com.apple.(etc) while the third-party developers will receive it as com.paragon-software.filesystems and ch.tripmode.TripModeNKE

It’s better for some applications to move in a trash file and then allowing your admin password to change.

For more third party preferences panes head over to system preferences, such as paragon hides the uninstall option from the settings.

What Is Another Alternative For High CPU Usage?

High CPU Fix: Clear Memory and Increase RAM in Windows 10/8/7 ...

Well here is another alternative for this purpose but this one is a bit risky one as compared to others as it says to remove Apple’s own kernel’s extensions.

Yes, you heard it right even though we won’t suggest you need to work this out in case any other option didn’t work only in that case!

Because this solution will definitely affect the usage of the high CPU. This is a very useful log for you to see all the details related to kernel_ task. 

  • Make a backup of your Mac using the time machine method. When your mac is in recovery mode turn off the system integrity protection.
  • Start finding your Mac’s model with the help of victors method by using the command 

system_profiler-detailed mini grep ‘Model identifier’

  • Then you need to run the following command very carefully  

cd /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources

Backup the relevant files of your model and restart your device into recovery mode and turn on the system integrity protection and start running the csrutil disable command.

And you need to bear in mind that this is a temporary fixing solution for your Mac if you’re struggling with it after trying all the other mentioned solutions. 

Even if you restart the Operating System or do this process after a software update the apple will restore the file which you removed earlier. 

Moreover, if you keep the mac up to date then you will not face any uncertain situation, and notice the fact that every update has its own new feature and capabilities along with it but can be available in the form of bugs as well so be aware of it.

Conclusion!!

Having said that the guide for the kernel_ task came to an end.

Just make sure you’re not relying upon the new features introduced in every update and that’s where your Mac is absolutely perfect!

Lastly, we hope that this guide was helpful for you and the solutions we have provided will help you eliminate problems related to kernel_task.
