# WhatCable – macOS menu bar diagnostics for USB-C

> WhatCable explains cable speed, charging limits, e-marker data, and connected devices in plain English. No more guessing why a cable charges slow or refuses to drive your display.

Ich habe zu Weihnachten USB-C-Tester verschenkt, aber das hier ist definitiv komfortabler, u.a. weil man in der Regel immer weiß, wo der Mac ist. Die Software ist [Open Source](https://github.com/darrylmorley/whatcable) und finanziert sich über einen 4,99 Pfund teueren [Pro-Tier](https://www.whatcable.uk/pro).
