WhatCable Demystifies USB-C Cables on Mac
WhatCable is a free macOS app for Apple Silicon that reads built‑in macOS data to reveal USB‑C cable specs—speed, power delivery, and capabilities—so users can identify labeled cables and quickly determine compatibility. The Pro version adds organization, live monitoring, diagnostics (like water damage and pin tests) and port health, priced around $13 for a lifetime license, though the free version already provides fast, useful details for managing cables with external displays and devices.
