sACNView is a Networking app for Mac.

About

sACNView is a free, Apache 2.0-licensed tool for viewing, monitoring and testing ANSI/ESTA E1.31, also known as Streaming ACN. It helps inspect lighting-control data carried over Ethernet networks and is available for macOS, Windows and Linux.

Features

Inspect universes, sources, channel levels, priorities and sequence errors; graph levels over time, transmit test data to one or multiple universes, and capture or replay snapshots.

Install on macOS

With Homebrew installed, run brew install --cask sacnview. Alternatively, download the official version 3.1.0 DMG, open it and drag sACNView.app into Applications. Launch it from Applications and select the network interface connected to the lighting network before monitoring or transmitting. Test transmission can affect connected lighting; use it only on an authorized network.
