See cpu usage mac10/14/2023 Select the CPU tab to see their CPU usage, ranked from the highest to the lowest. To check what’s causing high CPU usage, go to Finder > Go > Utilities and open Activity Monitor, which displays all the processes active on your Mac in real-time. Here are some ways you can do this: Use Activity Monitor to close processes To fix the issue, you need to reduce your Mac’s CPU usage. In simple terms, if kernel_task notices certain other CPU-demanding processes (rendering a 4K video, for example) are using up a lot of your Mac’s resources, it will itself hog resources, stopping the other processes from using them all and potentially overheating your Mac. One of its primary functions is ensuring your Mac doesn’t overheat. The kernel_task process is at the core of macOS, and it includes a variety of low-level functions that allow the computer to work. If you’ve tried shutting down all open apps, but your Mac is still running slowly, the issue could be being caused by the kernel_task process. If this sounds familiar, you should fix this problem as soon as possible! But how? you can also "grep thermal" if you are only interested in that.Today, let’s talk about how to fix kernel_task high CPU usage on Mac.ĭo you sometimes notice your Mac starts to run slow and will often take a long time to respond? Or you frequently hear the internal fan running at high speed, trying its best to stop your Mac from overheating and damaging its internal components. You will notice the frequency details and also some thermal info. : SYSCALL XD 1GBPAGE EM64T LAHF LZCNT RDTSCP TSCI 7_features: RDWRFSGS TSC_THREAD_OFFSET BMI1 AVX2 SMEP BMI2 ERMS INVPCID FPU_CSDS MDCLEAR IBRS STIBP L1DF SSBD : FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX SMX EST TM2 SSSE3 FMA CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC MOVBE POPCNT AES PCID XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C Or thermal / temperature details only? sysctl -a | grep thermal (but apple maybe removed the details from this to just numbers 0 or 1?) sysctl -a | grep cpu | more sudo powermetricsĪnd at the bottom you will see the following. There are 2 main ways to view your CPU stats if you don‘t want to install additional software you can view a lot of details from the terminal / command line.
