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.
