do any other PMU tools run in parallel? you can try to run pcm with the -r flag

[zhaowq32]

It's not working with -r flag.Maybe iStats Menus?

[rdementi]

try to stop the other app you suspect and re-run "pcm -r"

[zhaowq32]

Still not working

[opcm]

[zhaowq32]

No,i will have a try with sudo.

[zhaowq32]

could you try the released version here (https://github.com/intel/pcm/releases/tag/202311 )? Recompile both the PCM MSR driver and PCM itself please

There is a different error "IOServiceOpen returned 0x10000003" above which might point to the issue: PCM MSR driver could not be loaded. Did you try the manual install procedure: https://github.com/intel/pcm/blob/master/doc/MAC_HOWTO.txt
Could you share the output of kextstat ?

Requires kext signing or turning off SIP.
