1 Kernel_task is using all my CPU. Restart didn't work.
So my friends Mac began to become incredibly slow. He restarted it and it was still slow. The fan was running like a jet engine, so I checked the activity monitor. Turns out, the Kernel_task was using all of my CPU. I googled what it was, but I don’t know why it turned on as the computer is now cooler that the surrounding air. Any fixes?

So I looked at the activity monitor, and the Kernel_Task is still rampant. I saw however, that a “kextd” was running. I remember that when I researched the problem, kextds could be the root of it. Any fixes for this?

Did something happen to the system?
Dropped, spilled drink into keyboard or trackpad, or sat onto a wet surface.
The system is in Safe Mode as one of the thermal or voltage sensors is telling SMC there is a problem. You need to figure out what happened. Run the onboard diagnostics restarting the system and pressing the D key. Apple messed up the firmware in some releases of macOS so if it fails to run we'll need to try other methods.

Actually, no. It was just running normally. Nothing happened.

@jeveisback - Did you run diagnostics?

My friend hasn't had time to, will ask him tomorrow
On the positive side it seems to be gradually (extremely gradually) cooling off, so it might be fine by this morning. If it isn't, then I guess we'll have to.
