USB-C Inspector

See exactly what your USB-C and MagSafe cables can do — charging watts, data speed, Thunderbolt, and connected devices — directly from Raycast.

Requirements

• Apple Silicon Mac (M1 or later). USB-PD / e-marker data is not available on Intel Macs.
• macOS 14 (Sonoma) or later.

You do not need to install WhatCable separately. On first launch the extension downloads the notarized CLI from GitHub Releases and verifies it with SHA-256.

Commands

• Show All USB-C Ports — list every USB-C and MagSafe port with side-by-side details.
• Check Connected Cables — same view, filtered to ports that currently have something plugged in.

Optional setup

If you already manage a whatcable binary yourself, set WhatCable CLI Path in the extension preferences. Otherwise the extension auto-detects WhatCable.app / Homebrew, or downloads the official CLI.
