Everybody using zoom frequently knows the issue: You say something and forget to mute yourself, sometimes leaking funny information to your collegues. You just need a bigger indication, that you are not muted!

This is a simple MacOS app build in swift that runs in the background. To check if zoom is on mute or not, a JXA script is fired, checking, if the zoom window is muted or not. There are two different ways to indicate the mute status:

1. Menu bar icon: The menu bar icon changes color depending on the mute status. It is a simple red dot, that turns red when unmuted.
2. Window border: The window border of the zoom window changes color depending on the mute status. It is a simple red gradient when unmuted.

mkdir -p ./build

swiftc -framework Cocoa -o ./build/App main.swift App.swift BorderController.swift MenuBarMutable.swift WindowBorderMutable.swift

./build/App --withMenuBarIndicator --withWindowBorderIndicator

Feel free to automate the startup

The app includes a preferences dialog where you can configure:

• Enable Border Indicator: Show the window border indicator (default: enabled)
• Mute Button Text: Set the text of the mute button in Zoom (default: "Mute audio")

• You need to have at least MacOS Yosemite since the JXA script is not supported in older versions.
• The executing app needs accessibility permissions to get access the zoom app menu bar entries. Note: When you start the app via shell, it's the shell which needs permissions as well.
