Welcome to the WhatCable blog.

This is where I'll write about the messy, fun world underneath USB-C: why your
fast cable charges slowly, what a Thunderbolt 5 cable actually negotiates with
your Mac, which e-marker fields are honest and which are theatre, and the odd
counterfeit or quirk that turns up in cable reports.

## What you'll find here

A few rough buckets:

- **Releases**: what shipped in the latest WhatCable version, and why.
- **Deep dives**: long-form pieces on the spec, the IOKit data, and how the
  app reads it.
- **Investigations**: single-cable mysteries, mostly from community reports.
- **Guides**: practical "how do I know if X" walkthroughs.
- **Notes**: short observations, dev diary entries, posts like this one.
