WhatCable is a new open-source macOS menu bar app that identifies USB-C cable capabilities by reading the cable's embedded data. It displays information about charging wattage, data speeds, display support, and Thunderbolt compatibility in plain English. The tool addresses the common frustration of indistinguishable USB-C cables with varying capabilities.
Background
USB-C cables often look identical but have vastly different capabilities in terms of power delivery, data transfer speeds, and video support, making it difficult for users to identify which cable supports which features.
