Kernel Task is using 1000% of The CPU on macOS Catalina [duplicate]
My MacBook Pro running on macOS Catalina is really slow and the kernel task is using 1000% of the CPU !!
I tried all the solutions suggested in MUF How to Fix Your Mac’s “kernel_task” High CPU Usage Bug. I still have the same problem.There is only one solution that I was not able to do exactly like it was mentioned, it is the one suggested by Victor Petterson in How to fix kernel_task CPU usage on Yosemite.
It involves removing the « model identifier ».plist file. I was not able to find the file with my model identifier so I removed all the files in : ../ACPI_SMC_PlatformPlugin.kext/Contents/Resources
After removing the .plist files I have restarted my MacBook and re-enabled the SIP. Now the files are removed and the kernel task still using 70% of the CPU with a maximum speed of fans.
Does anyone have the same problem and was able to find a solution to the kernel task issue which is different from the ones mentioned above ?
Kernel_task is a dummy process which takes up CPU resources from other applications in order to cool the system down. So I would look at your system's cooling, maybe use fan tools such as Mac Fan Control and perhaps disabling turbo boost with a tool such as TurboSwitcher. Also on some MacBook Pro's you can cool the system a bit by using a TB3 port on the right-hand side to charge from rather than the left.
Some other issues related to Kernel_task problems.
- Update software (so bugs get fixed)
- Check for malware.
- Adobe Flash! if you have this uninstall it is well known using up CPU resources. It is not needed anymore.
- Boot into safe mode see if that solves the issue
- If #4 works try uninstalling third-party software with kernel extensions (kexts) by using AppCleaner or CleanMyMac X,
find them using terminal
kextstat | grep -v com.appleand match them to the software packages. Do not remove Apple's, hence the command line filters them out of the listing of extensions. - Use System Preferences -> Users & Groups -> Login Items and remove those applications you don't need to start upon login.
- Clean out your system using a tool like CleanMyMac X and uninstall applications you no longer use.
- Try resetting NVRAM
- Upgrade macOS 10.Reinstall macOS
