Hello Asankat272,


Thanks for posting your concern regarding your Mac in the Apple Support Communities.


Apple Article - HT207359 specifically references high usage output for the kernel_task. I recommend that you perform a troubleshooting step of Resetting the SMC in order to attempt to resolve your issue.
