How do I stop kernal_task. It's causing the spinning cursor and my computer is running super slow. This started happening when I upgraded to Yosemite.
Mac mini, Mac OS X (10.7.2)
First try:
Problem with Kernel Task - El Capitan
There will also be a kernel task running but it appears that yours is using too much CPU.
If still problem
Run this and post the results here so we know more about your configuration.
When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any one of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.
When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.
If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.
It looks like I have found a place to ask this question. I'm dealing with an early 2011 15" MacBook Pro with a completely dead battery. Just installed ElCapitan on it and it's basically unusable due to too the Kernel task.
I saw one explanation that this might be due to the dead battery and the automatic "throttling" by MacOS. I tried following the instructions to boot in Recovery Mode then use Terminal to give the command crsutil disable, then reboot to remove part of the kext file. But when I boot in recovery mode (which seems to take about 10- 15 minutes and pull down the Utility menu to Terminal, it does not recognize the CRSUTIL command. I know I can't do anything with that kext file without disabling that security. Is there another way to get the Terminal command to work?Is there another way to eliminate the throttling? could it be that there's a completely different approach to this problem or that the battery has nothing to do with it?
Booting in Safe Mode the MacBook seems to run pretty normally.
I hope someone here can offer some good advice.
