Why kernel_task use 500-600% CPU
Hi. I have changed the display of iMac 27" EMC 2546 . Remove SSD because it was'n working. Inside present HDD 3Tb WD. I have reseted SMC, PRAM and reinstalled Mac OS. The fan RPM is 6600. I have installed Mac Fan Control. The kernel_task use 500-600% of cpu and I can't determine why. Do you have any ideas why kernel_task overload CPU?
