Petersson's initial post focused on Mac OS X Yosemite, though he later followed it up with updates for later versions of macOS. In his case, it was likely caused by a dodgy sound card. However, if you've tried everything else and are still seeing kernel_task causing high CPU usage, this is a solution you may want to try.ĭeveloper and blogger Viktor Petersson has written extensively about kernel_task and the issues around it. The final solution here is a bit of a risky one: removing Apple's own kernel extensions. Still Have High CPU Usage? What to Do When All Else Fails
This results in better system stability, so you should see this issue less often in modern versions of macOS. System 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 system security. Starting with OS X El Capitan, Apple introduced a new security feature that broke a number of third-party modifications. For the rest, head to System Preferences and look for any third-party preference panes. Others may include a PKG uninstaller file you need to run. For some apps, that simply means moving the application file to the Trash, then inputting your admin password to allow the change. The best way to remove these, is to uninstall the associated software.

Meanwhile, third-party drivers will have the developer name in them, like this: This will show what kernel extensions are currently loaded. To dive into this, reboot your system as normal and launch Terminal. Safe Mode loads only the required kernel extensions, so if the problem doesn't occur in this environment, it points to an issue with a third-party kext. To do this, restart your machine and hold the Shift key as it boots. One quick way to check if a third-party kext is causing your kernel_task issues is to reboot your machine into Safe Mode.

Some software will install third-party extensions as drivers, or for controlling hardware. Also known as "kexts," the vast majority of these extensions are installed by Apple as part of the core macOS environment. Some people have had success in removing kernel extensions, which are modules of code able to perform low-level tasks. You can also find it under Applications > Utilities, and you might want to pin it to your Dock for even quicker access when you run into major issues.ĭigging a Little Deeper Into Mac's High kernel_task CPU Usage You can open Activity Monitor using Spotlight: just hit Cmd + Space then start typing "activity" and it should pop up.

If your Mac appears to be running slowly, is generating a lot of heat, or sounds like it's about to take off due to high fan speeds, then you'll want to open Activity Monitor and find out why. We've seen this a lot, so we've got a handful of tips to help you get rid of this problem. This means that figuring out the culprit can be tough. On your Mac, kernel_task is the name given to a variety of low-level functions that allow the rest of your computer to work. If you've shut down all the programs you can, and everything on your Mac still feels like it's moving through molasses, this could be a sign of the dreaded kernel_task causing high CPU usage. It's never fun when your computer starts running slowly, but it's even worse when you can't figure out why it's so slow.
