README 原文摘要

# WhatCable

> **What can this USB-C cable actually do?**

A small macOS menu bar app that tells you, in plain English, what each USB-C cable plugged into your Mac can actually do, and **why your Mac might be charging slowly**.

USB-C hides a lot under one connector. Anything from a USB 2.0 charge-only cable to a 240W / 40 Gbps Thunderbolt 4 cable, all looking identical in your drawer. macOS already exposes the relevant info via IOKit; WhatCable surfaces it as a friendly menu bar popover.

> [!IMPORTANT]
> **Upgrading from 0.5.x to 0.6.0?** WhatCable's bundle ID changed from `com.bitmoor.whatcable` to `uk.whatcable.whatcable` in 0.6.0 to match the new `whatcable.uk` domain. The in-app "Check for Updates" path in 0.5.x will refuse to install 0.6.0 because the downloaded bundle ID won't match what it expects. Upgrade through Homebrew (`brew upgrade --cask whatcable`) or by downloading [the latest release zip](https://github.com/darrylmorley/whatcable/releases/latest) and replacing `WhatCable.app` manually. Your preferences and notification permissions will reset on first launch of 0.6.0; re-enable launch-at-login from Settings if you had it on. This only affects the 0.5.x → 0.6.0 transition.

## What it shows

Per port, in plain English:

- **At-a-glance headline:** Thunderbolt / USB4, USB device, Charging only, Slow USB / charge-only cable, Nothing connected
- **Charging diagnostic:** when something's plugged in, a banner identifies the bottleneck:
  - *"Cable is limiting charging speed"* (cable rated below the charger)
  - *"Charging at 30W (charger can do up to 96W)"* (Mac is asking for less, e.
