Couldn't open IO Service on macOs Monterey 12.1

[Vadim-Podlevsky]

Compiled your code today to undervolt my 2015 MacBook pro with Intel 4980HQ. It feels like I'm close to making it work but must be missing something:

./voltageshift info

Couldn't open IO Service

And this is my settings after csrutil enable --without kext in recovery mode:

sudo csrutil status System Integrity Protection status: unknown (Custom Configuration).

Configuration: Apple Internal: disabled Kext Signing: disabled Filesystem Protections: enabled Debugging Restrictions: enabled DTrace Restrictions: enabled NVRAM Protections: enabled BaseSystem Verification: enabled

This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.
