Cable Detective tells you exactly what each USB-C, Thunderbolt, and MagSafe port is doing on your Apple Silicon Mac, right now.
USB-C ports look identical. They behave wildly differently. Plug something in. Cable Detective decodes the live state for that port:
- Power direction and wattage. Who is charging whom and at what negotiated USB-PD contract. The charger's full advertised PDO menu, the selected PDO, and the rated maximum.<br>- Cable identity. SOP / SOP' / SOP" e-marker reads. Vendor and product IDs decoded against the USB-IF database. No invented specs when the cable does not answer.<br>- Data speed. USB 2.0, USB 3.x SuperSpeed, USB4, Thunderbolt. The lane state, not the marketing on the box.<br>- DisplayPort lane state. How many lanes, at what link rate (RBR, HBR, HBR2, HBR3, UHBR), whether the alt mode is actually active, and how many display sinks the controller sees.<br>- Connected devices. The accessories behind a hub or dock, identified by their USB host descriptor and physical port path.<br>- Plain-English explanation. An optional Apple Intelligence layer summarises the report. On-device only. Off by default.
Cable Detective has zero network. There is no server. No account. No telemetry. No analytics SDK. No crash reporting. The optional AI explanations run on Apple's on-device Foundation Models, on your Mac. If we wanted to phone home we would have to ship a new build with new entitlements. We do not.
Apple Silicon (M-series) Mac running macOS 26 (Tahoe) or later. Apple Intelligence is optional and can be enabled or disabled at any time.
One-time purchase. No subscription. Lifetime use of the version you bought. Family Sharing supported.<br>more

What’s New
Version History
Version 1.2.0:
- New "Did we get something not quite right?" button at the bottom of every report. Copies a redacted version of the report to your clipboard and opens your browser at a feedback page where you can review what gets sent, attach photos, describe what was wrong, and optionally drop your GitHub @handle for notifications. Cases become public issues at github.com/Arthur-Ficial/cable-detective-cases. The app itself still has no network entitlement.<br>- Privacy: every copy operation now strips your Mac's platform serial number, hardware UUIDs, hostname, board ID, regulatory model number, and any connected USB device serial numbers before the text reaches the clipboard. Your Mac model, OS version, and all cable / power / port diagnostic data are kept. The on-screen display continues to show your own raw values.<br>- Settings -> General -> Feedback: toggle to hide the feedback button if you don't want it.<br>1.2.0 May 9
