you can also "grep thermal" if you are only interested in that. 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 I know that using Activity Monitor we can see CPU utilisation.But i want to get this information of my remote system through script. sudo powermetricsĪnd at the bottom you will see the following. When checking memory usage via iStat, I can see that kernel_task is using 1.61 GB (oof, Firefox is using 6.36 GB).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. I often suspect it is either due to the VS Code/npm/node/Slack thing, or kernel_task, or maybe something else I’m unaware about. Often I also have Slack open, and I know that’s a web app using Electron to run as a desktop application, which can be notorious for performance. I also run iStat v6.30, and sadly I have only 21 GB of free space on my HDD (out of 500 GB…). I use VS Code for programming which can have a lot of background tasks, same with using node/npm which can probably be doing lots in the background. To me it seems more like a software thing. I’m curious if it is a software thing or a hardware thing. Now with no external monitor plugged in, every once and a while the kernel_task rises up to 300% and sometimes rarely to 500%. Still get same issues with the external monitor.
Shut down the computer and turned it back on.I also use Google Drive’s “Backup and Sync” and do lots of web development with `node_modules` folders, that can have 10s of thousands of small files which I think results in CPU churn.Performed the Apple Diagnostics test (ADT - some older websites called it the Apple Hardware Test - AHT) and had no issues come from that.Reset the System Management Controller (SMC).Disabled Spotlight indexing for specific types of content and also added folders like “/System” in the Privacy settings.Disabled Energy Saver - Automatic Graphics Switching on both Battery and Power Adapter mode.I researched a lot online and did the following: Since I plugged in an external monitor (via thunderbolt) my kernel_task ramps up to 500% and can’t do much on my MBP.
