Angry IP Scanner
Angry IP Scanner is an open-source network scanner for macOS that quickly checks IP ranges and shows active devices and basic network details.
What is Angry IP Scanner?
Angry IP Scanner is a network scanning utility for macOS, Windows, and Linux that helps users discover active devices on a local network or across a specified IP range. It is designed for IT professionals, administrators, developers, and advanced home users who need a fast way to inventory hosts, troubleshoot connectivity, or identify unknown devices on a network. The app can scan IP addresses, resolve hostnames, show MAC addresses when available, and check ports using additional fetchers. Results can be sorted, filtered, and exported for later review or documentation. On Mac, it is typically used as a standalone desktop app rather than a background service. Angry IP Scanner is published by Azib and is best suited to users who understand basic networking concepts and need a lightweight utility for discovery and troubleshooting.

Safety overview
Status: Mostly safe
Angry IP Scanner is legitimate network utility software, but it actively probes IP addresses and can reveal device and network details on systems you scan. That behavior is normal for its purpose, yet it may trigger security tools or concern network administrators if used on networks where scanning is not expected. Use it only on networks you own or are authorized to test, and download it from the official site to reduce the chance of tampered copies.
Recommendation: Keep Angry IP Scanner if you use it to discover devices, troubleshoot local networking, or audit IP ranges. If you no longer perform network scans, you can remove it without affecting macOS. Before using it on workplace, school, or shared networks, make sure network scanning is allowed.
