About the app

WhatCable reads USB-C cable data from the IOKit registry using Apple's public APIs, no root access, no SIP changes, no private entitlements. It shows charging speed, data rate, Thunderbolt support, e-marker data, and identifies where the bottleneck is. Free and open source (MIT licence), with 5.3k stars on GitHub. Optional Pro tier at £9.99 one-time. Requires Apple Silicon, macOS 14 or later.

About the developer

Darryl Morley is a self-taught developer based in the UK. He works in e-commerce by day and builds Mac software in his spare time under Bitmoor Ltd. WhatCable started as a tool to answer a question he kept asking himself, which of these identical-looking cables actually does the thing, and turned into something other people wanted too.
