Kernel_task Is making Mac Slow To Use

Hello, everyone recently My MacBook Air has slowed down it’s weird because it never happens before and this is the first Time it happend I check activity monitor and saw Kernel_task taking up my CPU so I did a reinstall of Mac OS and that didn’t solve my problem so I did a NVRAM reset which also didn’t work then the last option was to do a SMC reset which worked but then the computer died because I could charge my computer when I do an SMC Reset any help so I don’t constantly do an SMC Reset Thank You

Answer this question I have this problem too

Is this a good question?

I would run the onboard diagnostics to see if any errors pop, if not they you likely have a OS/software level issue.

Restart your system and press the D key, let us know the error codes if you get any.

Reference: Mac startup key combinations

You may also want to check your battery as your systems age is getting near its time for a new battery. Install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see Adding images to an existing question


You could also try clicking the "Kernal_Task" on Activity Monitor and Force Quit it.


@lyonmissions - The system would crash if you did that!


Oops. Sorry about that!


I've seen this problem a lot lately.
