My MacBook Pro 16" is very slow from one day to another.

Hi there,

my MacBook pro 16`is very slow from one day to another.

The Activity Monitor shows that the kernel_task has a very high cpu usage. (see screenshot)


What I tried so far:


  • Did a clean install of OSX Ventura (before Monterey was installed)
  • Installed a fan control software: fans are working (computer is running very silent)
  • Cleaned the fans
  • Checked the temperature of the cpu: 37 C (seems ok, right?) (see screenshot)
  • Did a SMC and VRAM reset. (several times)
  • Installed a Virus Scan Tool (found nothing)
  • runned être check (see être check text file)


what could it be? I would be so grateful if you could help me.

Thanks a lot for every hint!

After trying many things, I found a solution that worked for me.


I installed MacOs Catalina (I had Monterey/Ventura before) to remove the "IOPlatformPluginFamily.kext" from extensions, but unfortunately it was not possible to rename/remove it even in this older MacOs Version. So I followed this instruction (it was for Big Sur but worked for Catalina as well …) https://apple.stackexchange.com/questions/372684/how-to-delete-kexts-in-catalina


maybe this helps someone …

Hi


The kernel task is a system process designed to protect your Mac from a process that is using excessive resources. the kernel pretends to use it to stop the other process from hogging your CPU. you do not need to fix the kernel task, instead find the problem the kernel task is protecting you from


if this issue continues after a reinstall it is not the macOS, so its time to look at 3rd party apps/extensions


I would recommend Time Machine before going any further


Disconnect everything from your Mac including the external monitor - remove the following apps iScherlokk , and the fan monitoring app too


then restart you Mac - if have other user account test in there too - if not create a test one

Thank you very much for your reply.


I removed Sherlock and the fan control app and a restart, but the cpu usage is high like before (it had been already high before I installed the 3rd party apps).


I did a clean install, so there is no external software on the MacBook anymore. Even no data files any more … so I don’t need a Time Machine backup - nothing to loose :-)


I created a new user account and after five minutes the kernel task was there again. The system needed from the beginning 63 %.


when I switched of the MacBook for a short time the background of the monitor was disrupted, could it be a graphic card error? How can I check this?


the Apple Hardware Test is not working, the connection to the internet fails.


thank you for any tips
