No matter what anyone else says IT IS A SIERRA INSTALLATION ISSUE!!!

No it is not. If it was there would be hundreds or thousands of posts about it. There is something else, likely third party apps and your specific system configuration that are causing overheating if indeed there is overheating.

Yes it is. I tried this in Safe mode when no 3rd party software is loaded and the same happened.

Then I figured out that disconnecting the external monitor from the Mini Display Port fixed the issue. Any time I connect my external monitor to the Mini Display Port kernel_task go crazy.

There you have.

So how does that indicate a Sierra installation problem? Try these:

Reset the System Management Controller (SMC) on your Mac - Apple Support

How to Reset NVRAM on your Mac - Apple Support

I tried all of that and + Safe Mode... nothing of that fixed the issue. Only what I told you.

It's a Sierra issue.

So, sell your Mac and buy something cooler.

The is nothing cooler than Mac 😉

Not according to you.

Many of you are being unhelpful, if you have nothing helpful to say, please don't bother clogging up the thread. This issue is very real and very much a Sierra issue. I have worked on approx 10 MacBooks recently and have proven that the issue ( high temps, with fan running excessively to try to cool) replicates itself across machines. None of the notebooks exhibited the issue before upgrading to Sierra.

All of the fixes reported have not solve the issue for me, it simply seems that at present the new OS has some issues and that I do not think will be resolved until 10.12.1 which is due this month.

Sorry

Don't come to a public forum and tell others what they may post.

This issue is not a Sierra issue it is your issue to fix, if you don't want help that is your choice,

Bye

Hi All,

If the FAN is running high it must have a reason.

In my case, I see that LOGD process is running at high CPU together with backup process, System log gets written full with like 300 messages/sec telling the system can't find some stuff.

I turned Time Machine off and problem solved, however missing backups now, which I don't like.

thanks,

Gerrit

I did not tell anyone what to say, I respectfully asked that if it was not pertinent not to clog up the thread.

I do want help and often use such forums for very helpful advice

The issue is caused by the Sierra upgrade and can be replicated so by association it is an Apple issue to investigate and resolve, either through communicative advice or mofication to their software. I am the recipient of the issue and I'm happy to process the resolution steps.

FYI, downgrading back to 10.11 does resolve the issue.

Has anyone had the issue from a clean install of Sierra?

No, you instructed, rather rudely as well, and you have absolutely no standing to do so.

I will leave you to fix it yourself, good luck.

As far as I can tell this thread has been hijacked by tigerruss. The OP has marked it as solved.

Glad to hear that his overheating problem is solved now.
