Hear a shared Mac app while reviewing

For a designer reviewing an app transition, the sound needs to match what happens onscreen. A beamed window is an individual app window from the other Mac, brought onto the desktop in front of you.

For Mac screen sharing with audio during that review, use Beam to bring over the app’s window, then enable audio for that window. You can see and hear it on the Mac in front of you. On the same network, picture and sound go straight between your Macs.

You can bring the app beside your local design notes and compare its response with the design you are checking. The selected window arrives at its own size and has its own Dock icon. Keep your notes open as you work through the interaction.

Run the interaction from the beamed window

Choose a transition in the app that produces sound. Use the sequence below to bring over its window, turn on its audio and trigger that transition from the Mac you are using.

1. Install Beam on two Macs running macOS Sonoma or later. Sign in to Beam on both and approve the new Mac. On the Mac doing the sharing, grant Screen Recording and Accessibility permissions, plus local-network permission when used.
2. Connect both Macs to the same network or your tailnet, the private network you set up with Tailscale. Keep both connected while you work through the review.
3. Open the picker, Beam’s window selection view, and choose the app window on the other Mac. Place the beamed window beside the design notes on your desktop.
4. Enable audio for the beamed window. That app’s audio plays on the Mac in front of you, so you can listen there while watching the app’s visible response.
5. Use your keyboard and mouse to trigger the transition with sound. Your input controls the app on the other Mac. Check what changes in the window and listen to the sound that accompanies it.
6. Minimize the original window on the other Mac and repeat the review. The beamed window stays available when its original is minimized, hidden or moved to another Space. Trigger the same interaction again and check the result.

The app runs on the other Mac while its window has a place in your ⌘ Tab and its sound plays in front of you. Record the visible response and audible result in your notes, then continue through the interactions you need to review.

Confirm the setup before moving the other Mac

The connection is encrypted and pinned to the paired Macs. With Beam, the sequence above gives the selected app window a place beside your local work.

Restart the other Mac, then reconnect through Beam and enable audio. Use your keyboard and mouse to repeat the interaction. Compare the result with your design notes and record whether the picture and audio match.
