![]() ![]() ![]() Switch to the Memory tab to check RAM consumption.Look up the CPU percentage in the % CPU column.In the Process Name column, find kernel_task (or use search).Go to Applications ➙ Utilities ➙ Activity Monitor.To see how much the kernel_task memory usage and CPU usage, you can use Activity Monitor: But, of course, it doesn’t always go as planned. It essentially throttles all the other processes, waits until they calm down, and then releases all the available CPU once again. What kernel_task is doing is taking over your CPU to prevent other tasks from using it. You can often find kernel_task high memory and high CPU usage explanation in that it is itself a highly demanding process. The primary goal of kernel_task is to bring your Mac’s internal temperature back to normal. But it has one important function - it springs into action when it detects that your Mac’s temperature is rising, or that some apps are starting to use too much CPU and thus heating up the processor. ![]() Just like many other processes that sound unfamiliar, kernel_task is essential to your Mac (as implied by its name), turns on as soon as you start your machine and runs in the background by default.įor the most part, kernel_task stays quiet. Let’s start with what the Mac kernel_task CPU process is and how to find it. The kernel_task high CPU issue is well-known and documented by now, so we have the exact steps you need to take to stop the kernel task taking up CPU it doesn’t need and prevent it from happening in the future. One of the most popular culprits (or default Mac processes) for spiking up your CPU is a kernel_task. Surprisingly, sometimes those tasks can overheat your Mac and even stall it completely. What we don’t think about is how much memory and CPU will be consumed by Mac’s default processes. When we buy our Macs and think of how powerful they should be, we usually take into consideration the requirements of our everyday tasks - text editors, web browsers, email and calendar apps, etc. Get an ever-growing collection of troubleshooting apps. ![]()
