Does not work on the M2

Line 203 in 1a9b691

| M2 | t8112 | Should work? |

The answer is regretfully no, it exits with a 133 code.

Confirming the same for me on M2 Max

sudo socpwrbud
zsh: trace trap  sudo socpwrbud

@JJ @sammcj finally got to it. Don't have an M2 machine to test but tried to fix some stuff up to make more portable in latest commit. Maybe it'll work now?

Great, thanks!

It builds in Xcode:

@sammcj sweet! for the make file ill just have to set the target to macosx 12.

But one thing does make me nervous about your output, are no core metrics working for the CPUs?

also, that out of order-ness of the gpu being under pcpu but above ecpu...its hurting my eyes lol
