Installing Iriun on a Mac is much like Windows, with one extra step: macOS asks you to grant camera permission before apps can use the feed. Here's how to do it cleanly.
- Download the macOS client from the official Iriun source and open the downloaded file.
- Install the app by dragging it into Applications, then launch it.
- Grant permissions. When prompted, allow camera (and microphone, if you want phone audio) access. You can confirm this later under System Settings → Privacy & Security → Camera.
- Install the phone app from the App Store or Google Play.
- Connect and select. Put both devices on the same Wi-Fi network (or use USB), then choose "Iriun Webcam" as the camera in your video app.
Common snag: If your Mac shows a black screen, it's almost always a permissions issue. Open System Settings → Privacy & Security → Camera and make sure both Iriun and your video app are enabled, then restart the video app.
The minimum supported macOS version can change between releases — confirm the current requirement on the download section before installing.
