BT Inspector
BT Inspector is a Bluetooth utility for macOS that scans nearby devices and lets you inspect their services, characteristics, and signal details.
What is BT Inspector?
BT Inspector is a Bluetooth inspection and diagnostics app for macOS focused on discovering nearby peripherals and examining the data they expose. It helps developers, tinkerers, testers, and advanced users scan for Bluetooth devices in range, view signal strength in real time, and inspect services and characteristics on connected peripherals. The app can read characteristic values, show model and version information when devices broadcast it, and help analyze how a Bluetooth device behaves during a session. Pro features add tools such as writing characteristic values, keeping a timestamped history of characteristic changes, exporting logs, and using Shortcuts actions for scanning and interrogation workflows. Published by George Garside, it is aimed at Bluetooth debugging, device analysis, and hands-on troubleshooting rather than everyday file or media tasks.

Safety overview
Status: Mostly safe
BT Inspector is a legitimate Bluetooth utility used to discover and inspect nearby devices. Bluetooth access and nearby-device scanning are normal for its purpose, and extended scanning can increase battery use while the app is active. Because it can read information broadcast by nearby peripherals and interact with characteristics, use it thoughtfully around devices you own or are authorized to test.
Recommendation: Keep BT Inspector if you use your Mac for Bluetooth troubleshooting, device development, or diagnostics. If you do not use Bluetooth analysis tools, you can remove it without affecting macOS beyond losing its inspection and logging features.
