How to fix high CPU usage error from kernel_task

So I found something called “kernel_taskIn Activity Monitor, you want to know what it is. The Good News: nothing evil. It is actually your operating system.

kernelIt, in case you weren’t aware, is the core of any operating system, and it sits between the CPU, memory, other components, and the applications you run. When your Mac boots up, the kernel is the first thing to start, and everything you do on your PC flows through the kernel at some point. The Activity Monitor places all this diverse activity under one heading: kernel_task.

If your computer is not running slow, don’t worry about this process taking up a lot of memory or using a lot of CPU at times: this is normal. Unused memory is wasted memory, so kernel_task will work on various things like caching files, updating OS which sometimes means using some CPU power.

But it’s never fun when your computer starts slow, but worse when you can’t figure out why. If you turn off all apps, background processes, and everything else on your Mac but it still seems to be moving slowly, this could be a sign that kernel_task It is causing high CPU usage.

on your Mac, kernel_task It is the name given to a variety of low-level functions that allow the rest of your computer to function. This means that figuring out who the culprit is can be difficult. We have seen this a lot, so we have provided a few tips to help you get rid of this problem.

Slow Mac Diagnosis

If your Mac seems to be running slow, generating a lot of heat, or seems like it’s about to fly due to high fan speeds, you’ll want to open Activity Monitor and find out why. As this is basically the equivalent of the Windows Task Manager on macOS. Activity Monitor is a useful resource and process management tool.

You can open Activity Monitor with Spotlight: just tap Cmd + Space Then start writingActivity“It should pop up. You can also find it under التطبيقات -> الأدوات المساعدة , and you may want to install it in your database to access it faster when you have big problems.

The reason why your computer is running slow should be obvious in the tab CPU. Just click the column header ٪ CPU To organize the running processes by using the processor. Anything that uses a large amount of processing power will show up on top; The details that are displayed will move depending on the different tasks in the background.

High CPU usage is only a problem when you least expect it. It is reasonable to expect that your device will consume resources significantly if you play a game, while watching a video in your browser, or when you are editing a video. If a single Safari tab or Mac process is using more than its fair share, it generally means that something has gone wrong.

Why is kernel_task the culprit?

You can kill most processes by clicking on them, then clicking X in the upper left corner of the screen. Unfortunately, you can’t do this with one specific process: kernel_task. The reason for this is that kernel_task It is actually part of macOS as we indicated at the beginning of the article.

It is not a single process, but is actually a series of operations under one title. As you work, macOS does all kinds of tasks in the background. This includes sending and receiving data over a network, writing and reading data to disk, and indexing new folders or disks to quickly search for them in Spotlight.

This process often uses a lot of the RAM you have available in the tab.memory‘, but this is less worrisome. The amount of RAM used will go up and down as required. However, high CPU usage can lead to poor performance of the entire system and may also cause the entire system to crash intermittently.

So how do you turn off kernel_task Negatively affecting the performance of your Mac?

Simple solutions to kernel_task problems

In many cases, restarting your Mac immediately fixes the problem. This is not always a long-term solution if you have been experiencing this problem for a while. Instead, it is a short-term solution that should provide immediate results.

Whatever is causing the high CPU usage may come back. So if you are facing frequent crashes, you may want to try resetting the System Management Console (SMC) as well. This is easy and can fix a wide range of macOS issues.

SMC reset instructions vary slightly depending on which Mac model you have. Since it can solve many problems, we have a complete guide that shows how to reset your Mac’s SMC. It also covers resetting PRAM, another part of your Mac that can cause various problems.

Other solutions for high CPU usage from kernel_task

Perhaps the most obvious fix for any operating system related issues is to update to the latest version of macOS. You just have to runSystem Preferences, and clickSoftware update’, and turn on any Apple software updates you might find.

Another common reason for high CPU usage is by process kernel_task It is Adobe Flash. Gone are the days when Flash was essential for browsing the web, but you might still need it to use an app or browse a specific website.

Instead of keeping Flash installed, you can use a browser like Google Chrome, which provides Flash (albeit optional). Most likely, you don’t need Flash at all, so it’s safe to remove it.

If you want to remove Flash completely, run Adobe Flash Player Install Manager and click Uninstall.

Dig a little deeper into the causes of high CPU usage from kernel_task

Some have succeeded in removing kernel extensions, which are units of code capable of performing low-level tasks. Also known askextsThe vast majority of these add-ons are installed by Apple as part of the core macOS environment. Some third-party applications also install these add-ons as drivers, or to control devices.

One quick way to check whether kext The third party that is causing the kernel_task issues is to reboot your device to safe mode. To do this, restart your device and hold the key Shift while it is running. Safe mode loads only major kernel extensions, so if the problem does not occur in this environment, it indicates a problem with a third-party kext.

To dig deeper into this, restart your system as normal and start the device. After that, run the command kextstat To see what kernel plugins are currently loaded. All Apple add-ons will look like[etc]. Meanwhile, third-party drivers will have the name of the developer, such as com.paragon-software.filesystems And ch.tripmode.TripModeNKE For example but not limited to.

The best way to remove it is to uninstall the associated application. For some apps, this simply means moving the app file to the Trash, then entering the admin password to allow the change.

Other applications may include a file Uninstall PKG which you need to turn it on. For the rest, head toSystem Preferencesand look for any third-party preferences. For example, Paragon’s NTFS driver hides the Uninstall option next to its settings.

starting from OS X El Capitan Apple introduced a new security feature that prevented a number of third-party modifications. System Integrity Protection, or SIP as the apps shortcut, stops injecting code into Apple apps, as well as writing to certain parts of the drive that Apple considers important to system security.

This results in better system stability, so you should see this problem less often on recent versions of Mac.

Still experiencing high CPU usage? What do you do when all else fails

The final solution here is a risky one: Remove kernel extensions from Apple. Doing so is not recommended. However, if you’ve tried everything else and you’re still seeing kernel_task consuming resources and causing high CPU usage, this is a solution you might want to try.

Developer and blogger Victor Peterson has written a lot about kernel_task and issues surrounding it. From his articles, it is likely that the cause is due to the sound card. Peterson’s initial post focused on Mac OS X Yosemite, although it was followed up later with updates to El Capitan and Sierra.

We haven’t tested this fix and can’t say if it will work for you. If you are interested in doing so, here is what you need to do:

  • Back up your Mac using Time Machine or another backup solution.
  • turn off”System Integrity ProtectionBy booting into recovery mode and running the command csrutil disable.
  • Follow Victor’s method. Start by finding your Mac model with the command system_profiler -detailLevel mini | grep "Model Identifier:".
  • Run the following command:
cd /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources
  • You have to move and backup the file to your form. For example, if the ID is MacBookPro8,2 it will work: sudo mv MacBookPro8_2.plist MacBookPro8_2.bak
  • Reboot into recovery mode and enable System Integrity Protection again with the command csrutil enable.

Again, this is a last resort. Only try it if you are struggling to get anything done due to kernel_task making your Mac unusable. This is not a short-term solution – it persists even after you reinstall your operating system.

However, you will also need to repeat this process after every major software update or any operating system upgrade, as Apple will restore the file you moved.

Is kernel_task a new problem?

Generally, upgrading to a new version of macOS brings new features and capabilities, but it can also introduce some bugs. This is especially true on older models of devices that are pushed to the limits. If you’re using a Mac that’s no longer supported, your model isn’t a priority for Apple.

Did you recently upgrade your version of macOS? If only after that you started seeing kernel_task problems on your Mac, that could be the cause. If you don’t count on the new features introduced in the latest update, you may be able to downgrade safely.
