whatcable

Whatcable is a macOS menu bar app that identifies the capabilities of each USB-C cable connected to your Mac, translating technical specs into plain English. It’s designed for tech enthusiasts, IT professionals, and anyone frustrated by unlabeled cables, helping them instantly know if a cable supports charging, data transfer, or video output. The project is interesting because it solves a common, overlooked pain point with a simple, elegant interface, turning guesswork into clarity for everyday productivity.
