v1.5.0 · 10d ago
macOS menu bar app that reports in plain English what each USB-C cable on your Mac can do and why charging may be slow.
Why you might care
Useful when a USB-C cable charges slowly or links at the wrong speed, since it reads cable e-marker and port data from IOKit and explains the bottleneck. It shows cable speed and current rating, plus USB-IF certification matched against a list bundled with the app, with no network lookups.
