So, it cannot record the audio from the MacOS system?

I am running this app on Mac OS 26.2, I noticed there is no sound from my recordings, although I were playing the music.

Audio capture is not supported in OpenScreen at the moment.

navigator.mediaDevices.getUserMedia does not work on macOS for audio capture due to a fundamental limitation whereby apps that want to access the system's audio require a signed kernel extension. Chromium, and by extension Electron, does not provide this.

There are workarounds to this via virtual devices but have not been looked into/planned as of now.
