Could you build this?
No Tracking real-time per-app power consumption in watts on Apple Silicon requires privileged access to private macOS IOKit metrics, powermetrics, and Mach task APIs.
What it would actually take: Requires a native macOS Swift/Objective-C app interfacing with Apple Silicon's IOReport, Mach kernel APIs, and powermetrics daemon outputs. Reverse-engineering private Apple Energy APIs and interpreting PMC (performance monitor counter) / CPU energy telemetry per task without root privileges or via authorized helper daemons requires specialized macOS kernel/systems engineering.
