kernel_task进程是mac的系统管理进程，kernel_task进程cpu占用率之所以久高不下是因为你的Mac的温度传感器坏了，并且向kernel_task这个进程传递了错误的信息，导致Mac以为自己的cpu温度现在特别高，所以调用kernel_task进程抢占计算机资源来降低其他进程的使用，使得cpu降频降温。

On your Mac, kernel_task is the name given to a variety of low-level functions that allow the rest of your computer to work. This means figuring out what the culprit is can be tough. We've seen this a lot, so we've got a handful of tips to help you get rid of this problem. Diagnosing a Slow Mac One of the functions of kernel_task is to help manage CPU temperature by making the CPU less available to processes that are using it intensely. In other words, kernel_task responds to conditions that cause your CPU to become too hot, even if your Mac doesn't feel hot to you. It does not itself cause those conditions.

Many MacBook users complain about their computer getting hot, slow and unusable from time to time. When they check Activity Monitor to see which task is causing the CPU to become unstable the problem is often found to be caused by kernel_task, which maxes out on CPU resources and causes the MacBook to become unstable. One of the functions of kernel_task is to help manage CPU temperature by making the CPU less available to processes that are using it intensely. In other words, kernel_task responds to conditions that cause your CPU to become too hot, even if your Mac doesn't feel hot to you. It does not itself cause those conditions.

well-established Machine Learning algorithms, with the only requirement being the definition of an adequate kernel function which reflects the task at hand.

However, the list of Macs identified by plist files has not been updated for some years. Many MacBook users complain about their computer getting hot, slow and unusable from time to time.

One of the functions of the kernel_task process is to help manage the temperature of your CPU. Activity Monitor might show that a system process named kernel_task is using a large percentage of your CPU, and during this time you might notice more fan activity.

Detailed examination showed, that process called kernel_task is … So, kernel_task responds to conditions that cause CPU temperature increase, even if you cannot feel this rise in temperature through the body of the Mac. According to Apple, this process does not generate conditions that increase CPU temperature. When the temperature of the processor decreases, kernel_task automatically reduces its activity. Hi guys, I´m looking for help. The kernel_task file takes almost 5gb of my memory and I have 8gb on my mid 2013 Macbook Air. Running 10.9.5. Seriously I cannot work anymore.

I think that things which take up a lot of CPU in kernel task are things that you plug into your computer, like an uncompatible mouse or flash drive. It took me weeks of research but finally I found the bug.I hope it helps for you!

In order to fix the kernel_task CPU usage on Mac, it is necessary to lower down the CPU temperature. This can be achieved by resetting SMC, improving airflow, using cooling pads, or uninstalling apps. Sometimes, the kernel_task CPU issue is caused by using external monitors or bad power cables.
