Your mouse lights up, but the cursor does not move.
The drive is plugged in, but it does not mount.
The dock is connected, but one device behind it is missing.
In moments like that, the first question is simple:
What does macOS actually see?
Device Inspector Pro gives you a live device tree with the details behind each connection.
See the device tree and negotiated specs
Device Inspector Pro helps you inspect connected hardware in a structured view.
Use it to see:
- the live device tree
- hubs, docks, and downstream devices
- exact device specs
- what macOS negotiated
- how a device is connected
- internal and external hardware
That makes it useful when checking USB, Thunderbolt, adapters, docks, drives, cameras, audio interfaces, keyboards, mice, and other connected devices.
Instead of guessing whether a cable, port, hub, dock, or device is the problem, you can see what the system detected.
