Hello Dan! Thank you for your answer. In brief, installed OS High Sierra from Scratch, erasing HDD first. The situation was: starting the system will be fine till random times from 5 min to 1 hour when kernel_task started eating CPU up to 100% making system unusable, very slow cursor, etc. specially running on battery power.

Remember, Kernel_task is the one which helps manage MacBook temperature by holding the processes that profoundly uses CPU. 2020-04-25 To verify that a kexts could cause high cpu usage, reboot the computer in safe mode and check if kernel_task uses too much cpu. If you find that in safe mode everything is ok, there seems to be a problem with a thirdparty. To start up in safe mode: Start or restart your Mac, then immediately press and hold the Shift key.

Here is the link to David Schlachter’s article on fixing kernel_task high CPU problem. As David and others have said after following the instructions found in David’s article, the fan keeps running at full speed but I think, like others, I can live with that for now. My kernel task CPU was 300+% all the time and the fan would start whirring seconds after I turn the computer on, and continue the entire time it was on. Everything functioned, but loaded at a snails pace and the computer was essentially almost unusable for anything practical.

I have the "CPU Simple" trace as well, however I don't see what could have caused this high kernel CPU usage. :( – Igor Malin Apr 20 '16 at 3:56 share the ETL (zipped to reduce the size) on OneDrive and post a link here. Extremely high CPU % for kernel_task, hardly any usage from any other application (just in case, I deleted VirtualBox and Adobe stuff - no luck), constantly audible fan, and no heat whatsoever.
