Runaway Kernel Task process

My Solution to fix a runaway Kernal Task issue

If you have been experiencing some weird issue with Snagit - like poor system performance. Maybe the kernel_task is more than 100%. There might be a logical problem.

Runaway Kernel Tasks

On my computer, I had multiple versions of Snagit installed. This is because every time that I did a major upgrade the computer kept the old version.

When the computer boots up it still uses the Snagit 2019 version and libraries. When I would do capture it would mix up which version to use and get stuck in an endless loop.

The quick solution was to remove all but the current version of Snagit. In my case, it's Snagit 2020. My computer performance had improved since removing the applications. (I also restarted the computer after deleting the apps)

I notice this was a problem when using Microsoft Teams and Zoom. I am not sure why using video apps would cause an issue. I think it's just the amount of CPU that is being used.

Try This Fix!

So if you are having problems related to kernel_task, you may want to check to see if you have multiple versions of Snagit. (I assume this might be true for other system base apps.)

Note: My problem was with Snagit, your situation might be a different application.

Your best bet is to restart the computer to properly test to see if removing the old applications fixed the issue.
