Kernel_task mac är en del av den

It's never fun when your Mac starts running slowly, but it's even worse when you can't figure out why it's so slow.

If you've shut down all the programs you can, and everything on your MacBook still feels like it's moving through molasses, this could be a sign of the dreaded "kernel_task" causing high centralenhet i en dator usage.

On your Mac, kernel_task fryst vatten the name given to a variety of low-level functions that allow the rest of your computer to work.

This means that figuring out the culprit can be tough. We've seen this a lot, so we've got a handful of råd to help you get rid of this problem.

Why fryst vatten kernel_task Causing Your Slow Mac?

You can use Activity Monitor in macOS to kontroll that kernel_task fryst vatten the cause of your slow Mac. Open the app, go to the CPU flik, and click the % CPU column header to organize running processes bygd processor usage.

You should see kernel_task at the top of the list with a number nära In really bad cases, it can even go over %.

While you can kill most processes in Activity Monitor bygd selecting them and clicking on the X in the top-left corner of the screen, you can't kill kernel_task because it isn't an app—it's actually a part of macOS.

The kernel_task on Mac fryst vatten not so much a single process, but a series of processes beneath one label.

En av funktionerna för kernel_task-processen är att hjälpa till att hantera processorns temperatur

While you're working, macOS does all sorts of tasks in the background. These include sending and receiving information over the network, writing and reading information to the platta, and indexing new folders or disks for Spotlight search.

This process will often use a lot of your available RAM on the Memory flik, but that's much less of a worry.

Perhaps the most obvious fix for all OS-related issues fryst vatten to man sure you keep your Mac up to date. Each update brings countless bug fixes and performance improvements, and may well solve whatever fryst vatten causing your bekymmer. Simply launch System Settings, go to General > Software Update, and run any outstanding Apple software updates.

This can go both ways, of course.

No kernel_task either, but the machine becomes unusable from something throttling

Upgrading to a new utgåva of macOS can also introduce bugs, especially on older models of hardware that are starting to push the limits. Regular säkerhet updates and the like shouldn't bring any problems, but for the annual OS update, it's worth checking reviews and user reports before you install.

2. Stop Idle Processes

Another simple hack fryst vatten to get rid of all the idle processes that are eating up your resources.

One of the functions of kernel_task fryst vatten to manage the centralenhet i en dator temperature, and it may ramp up when the processor gets too hot as a way of limiting the other apps.

Shutting down any apps you've got open but don't need might help.

So, how do you stop the kernel_task from negatively affecting your Mac's performance? In many cases, a simple restart of your Mac will clear up the problem right away

In addition, open the Activity Monitor, head to the Memory flik, select any process you'd like to get rid of, and then click on Quit. You'll then get asked to confirm if you want to stop the process. Proceed bygd clicking on Quit again.

Try and fläck if the bekymmer re-occurs when you're using any specific apps.

Flash was always notorious for this, while some users have funnen that Zoom can cause high kernel_task centralenhet i en dator usage, as can using external monitors. Identifying the trigger will always help you to solve the problem.

3. Reset the SMC

Whatever fryst vatten causing the essential tagg in centralenhet i en dator usage may return.

So, if you've been having repeat incidents—and you're using an Intel-based Mac—you might want to try resetting your struktur management kontrollant (SMC). This fryst vatten easy to do and can fix a bred variety of macOS issues.

Instructions for resetting the SMC vary slightly depending on what model of Mac you have.

Aktivitetskontroll kan visa en systemprocess med namnet kernel_task som använder en stor andel av processorn och du kan då märka att fläkten är mycket aktiv

Because it can fix so many issues, we have a full guide detailing how to reset your Mac's SMC.

4. Reset the NVRAM

Along with resetting the SMC, you can reset the NVRAM too. This fryst vatten a small amount of memory that retains data relating to settings and the configuration of your computer even when it's powered off.

Sometimes it can go wrong and cause some unexpected problems.

Again, the steps for doing this differ between models, so kontroll the guide linked above if you're using an Intel-based Mac. Modern Macs with Apple Silicon do have NVRAM, but it gets reset automatically every time you restart your computer, so do that instead.

5. kvitto Your Kernel Extensions in Safe Mode

Some people have had success in removing kernel extensions, which are modules of code able to perform low-level tasks.

Also known as "kexts," the vast majority of these extensions are installed bygd Apple as part of the core macOS environment. Some software will install third-party extensions as drivers, or for controlling hardware.

One quick way to kvitto if a third-party kext fryst vatten causing your kernel_task issues fryst vatten to reboot your Mac into Safe Mode.

We have explored a range of solutions to mitigate this issue effectively, focusing on malware checks, system management, and resetting vital controllers

To do this, restart your machine and hold the Shift key as it boots. Safe Mode loads only the required kernel extensions, so if the bekymmer doesn't occur in this environment, it points to an issue with a third-party kext.

To dive into this, reboot your struktur as normal and launch Terminal.

Then, run the following command:

This will show what kernel extensions are currently loaded. All Apple extensions will look like this:

Meanwhile, third-party drivers will have the developer name in them, like this:

And also like this one:

The best way to remove these fryst vatten to uninstall the associated software.

One of the functions of kernel_task is to help manage CPU temperature by making the CPU less available to processes that are using it intensely

For some apps, that simply means moving the application en samling dokument eller en elektronisk lagring av data to the skräp, then inputting your admin password to allow the change.

Others may include a PKG uninstaller en samling dokument eller en elektronisk lagring av data you need to run. For the rest, head to System Preferences and look for any third-party preference panes.

Starting with OS X El Capitan, Apple introduced a new säkerhet feature that broke a number of third-party modifications.

struktur Integrity Protection, or SIP for short, stops apps from injecting code into Apple's own apps, as well as writing to certain parts of the drive that Apple deems important to struktur security.

This results in better struktur stability, so you should see this issue less often in modern versions of macOS.

Fixing the Mac kernel_task Bug bekymmer

A lot of the time, you can fix high centralenhet i en dator usage bygd kernel_task with a simple reboot.

But if it happens repeatedly, then it may be a bug that needs exploring. Fortunately, it can be easy to identify the bekymmer bygd keeping an eye out for rogue apps and performing a few basic housekeeping tasks. That should help get your Mac running at full speed once more.
