WiFi Scanner
WiFi Scanner is a macOS wireless analysis app that helps users discover nearby Wi‑Fi networks, inspect signal details, and troubleshoot coverage or channel issues.
What is WiFi Scanner?
WiFi Scanner is a native macOS utility for analyzing nearby wireless networks and checking how your Wi‑Fi environment is performing. It is designed for home users, IT staff, and network administrators who need to see access points around them, compare signal strength, and identify channel congestion or overlap. The app presents scan results such as network names, channels, signal levels, and other radio details that help with router placement, troubleshooting, and optimization. It also includes tools for reviewing scan sessions, exporting results, and working with saved data for later analysis. Accessagility publishes WiFi Scanner for users who want a focused desktop tool for diagnosing everyday Wi‑Fi problems or evaluating wireless conditions in homes, offices, and other managed spaces.

Safety overview
Status: Mostly safe
This app is used to read local Wi‑Fi scan information, so requests related to network discovery and macOS Location Services are normal for its purpose. It is intended to inspect wireless conditions around your Mac rather than change system settings. As with any network analysis tool, use it only on networks and locations where you are authorized to perform scans, and review exported scan files before sharing them if they contain details about your environment.
Recommendation: Keep WiFi Scanner if you use your Mac to troubleshoot wireless coverage, channel conflicts, or access point placement. If you no longer analyze Wi‑Fi networks, you can remove it without affecting macOS, though any saved scan history or exported project data you want to keep should be backed up first.
