Hear your Mac

With BoxView Helper on a Mac with macOS 14.4 or later, the Mac's sound can play on your phone during a session.

#Turn it on

1. Connect to the Mac and open the session controls.
2. Under Mac sound & devices, tap Sound. It reads Playing here once sound arrives.

The first time, macOS asks on the Mac whether BoxView Helper may record system audio. Someone at the Mac clicks Allow. You can change it later in System Settings › Privacy & Security › Screen & System Audio Recording, in the System Audio Recording Only list.

#Volume and Mac quiet

• While Sound is on, a slider under the tiles sets the volume on the phone only. The Mac's own volume isn't touched.
• If the tile reads Not allowed, the Mac didn't allow BoxView Helper to record system audio. Turn it on in the Mac's System Settings as above.
• Mac quiet silences the Mac's speakers while you listen, so a quiet room stays quiet. Tap it again, or turn Sound off, and the Mac plays as before. The button reads Mac plays when it's off.

BoxView takes the sound before the Mac's volume and mute, so you hear it at full level even when the Mac is muted.

#Good to know

• Sound plays while BoxView is open. It stops when you switch to another app or lock the phone, and starts again when you come back.
• The Mac only sends sound while something plays. A silent Mac sends nothing.
• On macOS before 14.4 the tile reads Needs macOS 14.4.
