Notebookcheck reports on WhatCable, a free macOS app that displays each USB-C cable’s data rate and Power Delivery capabilities per port on Macs, helping users verify if a dock or monitor setup can run at full bandwidth; however, cheap cables without an E-Marker may not report speed, and Thunderbolt 3 cables can be misidentified, with a Pro version offering deeper insights.
WhatCable is a free macOS app for Apple Silicon that reads built‑in macOS data to reveal USB‑C cable specs—speed, power delivery, and capabilities—so users can identify labeled cables and quickly determine compatibility. The Pro version adds organization, live monitoring, diagnostics (like water damage and pin tests) and port health, priced around $13 for a lifetime license, though the free version already provides fast, useful details for managing cables with external displays and devices.
The Verge reviews WhatCable, a free Mac app for Apple Silicon that reads data exposed by macOS to show exactly how each USB-C cable performs—speed, power, and potential bottlenecks—by querying the cable’s e-marker and the Mac’s port controller; the app is free at core (with a Pro upgrade for additional diagnostics) and a Linux port is in development.
