Kernal tast at 80 to 400% CPU, really making life hard on the macbook Air. What can I do or even know what's causing this? Thanks.

What else is using CPU in Activity Monitor? Heavy use by the kernel is usually drivers in my experience. Either a busy driver, or one that's hung up.

Got any disk activity or network activity running?

Have you launched the Activity Monitor app to see what is running?

Yes, that's where I discovered the Kernal. But what is causing the Kernal? The point was my wifi was slow and hard to watch wifi TV when slow.

So tell us what else is using CPU in Activity Monitor. A screen shot would help. imgur is your friend.

imgur is a way to post images on the internet.

your wifi being slow is not your laptops fault. It could be verizon's fault, sure... or your laptop struggling to handle the data due to being full, using too many apps, etc.

how much space is left on your system hard drive. >25% free?
What else is running?

thanks Andi, 40gb available of the 120 GB drive. Not running too much on the laptop, but Mail, and that is a labot intensive app sometimes. But still Kernal saying $85%, then 200% what is that?

Seems to happen, I think more at night?....8pm than during the day. Kernal Task now say today, 2pm just 4.6%

30% free should be enough space.

We cannot help you unless you post a screenshot of activity monitor showing what else is running.

I DID an Etra check, Poor. Then deleted cache, and emails, then Excellent. Then internet slow, and ran Etrecheck and again poor.

Said there is couple of hundred Apple tasks, and deamons that failed due to insufficent ram, but does not say what the processes are that failed. I hardly have anything going on on my laptop! So baffled.

Last night I deleted Office 2011, could not find uninstalled so just trashed, and today see this:

Here is ETre check report from tonight.

Andi, I have not used 2011 in years, I'm now on 2016, and it was another gig or two of space.

kevs, I'm not sure what etrecheck is. What we need is a pic of Activity Monitor when the problem is happening. Sort by CPU%, with the highest usage at the top.

(shift-command-4) drag across Activity Monitor, release mouse button. (snapshot sound) picture file appears on your Desktop.

Go to imgur.com , create free account if you do not have one already. Upload picture. Click on the new picture in your account, imgur will show several sharing options. Copy the BBCode option, paste into a post here. The code to paste will look something like this: [img]www.imgur.com/blahblah/kevs/123/45/678/picture.jpg[/img]

Check /Library/LaunchDaemons/ for the Microsoft daemon and delete that.

Kernal task recently on laptop at 321%. Again, still not clear why the task is a mystery. Apple cannot know what is going on?

Maybe you need a app to find office 11 related files and delete them...
