285% CPU usage from kernel
I am currently using the new 2016 MacBook Pro 13 inch with touch bar, and I've had nothing but problems so far. The one problem that is effecting me the most is when the CPU usage sky rockets to 100%, fans going wild, and the computer because equivalent to a brick. No matter what I do the problem keeps occurring, happens quite often at about twice a day if I'm always using it, and not during any kind of intensive work. Watching activity monitor while this is happening shows kernel_task using over 200% CPU usage. I have done a full system restore and re-installed MacOS, and reset the SMC controllers twice. Does anyone have any advice on this problem? Thanks in advance.

Hello aussiebail1,
Keep Activity Monitor open. The next time you get a kernel_task spike in CPU usage, try to look to see which task is using the next highest amount of CPU. I've been studying these kernel_task CPU usage jumps. They may not be a real problem. They may be an attempt by the operating system to prevent some other task from running wild. Identifying that other task is the more difficult question. See If kernel_task is using a large percentage of your Mac CPU - Apple Support
Hey etresoft,
I attached a picture below of the last time I had a CPU spike and to me it doesn't seem like anything else out of the ordinary thats take a large amount of CPU usage. Let me know what you think, thanks!
Hello again aussiebail1,
Try getting rid of that "clean up" software.
I only installed that clean up software to help with the problem, so I'm saying the problem was around before I installed it. But I will remove it anyways.
UPDATE: Just had another incident, saw CPU usage spike to 500%, restarted it 3 times and the problem came right back once it booted up. After the third time I just let it sit until it calmed down.
This suddenly occurred with my older MacBook Air this week, and after trying everything else and much hunting, I found a solution elsewhere online that worked for me. This is definitely a hack that overrides several safety features, so use at your own risk. . .
Short version: remove IOPlatformPluginFamily.kext from your extensions library.
Long version:
My eventual conclusion after trying every possible trouble shooting step to no avail was that the apparent high kernel_task CPU usage was actually due to a feature called kernel throttling, which, so far as I can understand, is intended to limit CPU use by other processes when the computer thinks it is overheating. That is, the kernel_task is not actually using all that CPU, it just appears to be to limit other CPU use. This was confirmed by the fact that EntreCheck showed only a low CPU usage for kernel_task. Since my computer was not actually over heating, I concluded that a temp sensor had probably gone bad or some such.
Several others online reported good results from disabling kernel throttling in similar circumstances. Here's how in Sierra:
1. Restart your computer while pressing Command + R
2. Open terminal in the utilities menu and do: csrutil disable
This overrides the protection that would otherwise keep you from messing with certain areas of your file system, so you may want to enable again after you finish the steps here.
3. Restart in normal mode
4. Go to /System/library/extensions/ and locate the file called IOPlatformPluginFamily.kext
5. Move this file to a backup location somewhere outside the extension folder (in case you decide to replace it later)
6. Restart one more time
I've been using my computer all day with no further problems, system CPU usage back down to normal and no over heating. However, as I said this is definitely a hack, and I probably wouldn't have tried it with a newer computer. Mine is 4 years old and just needs to hang on a few more months until my work replaces it, so I'll happily take the slight risk of actual overheating to achieve that (and of course I have it fully backed up in case).
Hey entresoft
I am also facing same issue. Constant high CPU usage by the system (ranges between 68-80%). Activity monitor says that kernel_task is hogging the max CPU (mostly greater then 200%)
Steps tried so far
1. Deleted temp and cache
2. Uninstalled flash
3. Created a new admin user account (The issue continued with the new account as well)
4. deleted mediaanalysisd.plist file - by doing this the issue resolved for few hours and then the issue resurfaced.
