Install in three steps
- Open Mucast.dmg from your Downloads folder.
- Drag Mucast onto the Applications folder.
- Open Mucast from Applications. macOS checks the app and asks once whether to open an app downloaded from the internet: choose Open.
Your first show
- Choose Landscape or Portrait.
- Add a platform and paste its stream key, or sign in with YouTube or Twitch.
- Add your camera, screen or microphone to the scene.
- Press Go Live.
When you add a camera, microphone or screen, macOS asks you to allow that source once.
