  1. Without the Intel Power Gadget installed on Mac (a precondition), apply
  2. Run ./mach raptor -t raptor-speedometer --power-test

Expected Results:

Gentler/better error message?

I've attached the full error log from the run; I've also confirmed that installing Intel Power Gadget and re-running the same test in the same terminal window/shell fixes it just fine.
