Macbook Pro Kernel_task Problems

Hello,

I do not know how to continue. 

My Macbook (2019) is currently very slow (lag) and the kernel_task is quite high (sometimes up to 5000). 

It mostly happens when I start and stop playback in Davinci Resolve 18.5.1 Studio. 

Temperatures are completely in the green area. Have the Macbook also freshly blown out and cleaned which does not contribute to any improvement. 

I hope I can get more tips here. 

for your third party—

If in doubt refer to the developers website; Support/Help/FAQ/known issues/compatibility /updates...

etrecheck <Runtime: 9:07> this is abnormally slow... you would expect to see run time less then 3 minutes.

To trouble shoot further you can:

—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies

Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

This test will tell you if third party interference; most* extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 

unplug all third party peripherals when testing

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
