Kernal_task is using up a lot of CPU.

Can I resolve this issue and find out what is making the computer run hot. My fan is running at 6500 rpms always. I have downloaded macfanscontrol. Constant RPM value is set at 6500. Should I adjust Sensor Based value and what should it be?

MacBook Air 13″, macOS 10.13

Looks good except you\re running far too many Apps these days for only 8 GB of RAM.


I'd disable DropBox & OneDrive for a test.


Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode?


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Don't slow the fan down ever, could fry your Mac.


Trouble is everything runs off Kernal_task.


You can save us asking dozens of questions by submitting a report from this App for us to look at…

EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

<script src="https://pastebin.com/embed_js/KuvnghqA"></script>


The relevant part would be like...

Don't use these, they are just examples, yours will appear different.


Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
