Show HN: WhatCable, a tiny menu bar app for inspecting USB-C cables USB-C cables can be a mess. One cable charges at 5W, another does 100W and Thunderbolt 4, and they look identical in the drawer. WhatCable sits in your menu bar and reads the cable data your Mac already has access to. Plug in a cable and it tells you in plain English what it can actually do: charging wattage, data speed, display support, Thunderbolt, etc. Built in Swift/SwiftUI. Open source, free, no tracking.
