Operating systems generally provide very little information about the technical capabilities of connected ports and cables. Even USB-C cable manufacturers often hide useful details from users. Fortunately, there are utilities that can reveal the actual specifications of a connection.

[**WhatCable**](https://www.whatcable.uk/) presents information such as cable data transfer speeds, charging limitations, e-marker details, and connected devices in a clear and accessible way. This eliminates the guesswork when trying to understand why a device is charging slowly or why a cable cannot drive an external display.

The app requires no configuration. Simply click its icon in the menu bar to instantly view information about available USB-C ports and any connected cables.
