- Why is kernel_task using so much CPU? 5 answers
The activity monitor is showing strange things, like kernel CPU % usage being way above 100%, between 200% - 1.000%.
At the same time the cooling fan is running at max speed and the CPU temperature seems to be 47°. At the same time, everything started to react very slowly.
I am only running chrome with 3 tabs open.
What could be the problem? Am I reading the % correctly and why would it show >100%?
