Turn your iPhone and iPad into additional speakers for your Mac, and arrange them by device name.

Connect and share

1. Open Sidecar Speaker on the Mac and choose “开启连接” (Enable Connections).
2. Open the app on each iPhone or iPad. Allow local network access and select your Mac.
3. Approve each connection on the Mac. Then choose “开始共享系统音频” (Start Sharing System Audio) and grant the macOS audio-recording permission if prompted.
4. Play audio in another Mac app. Use “排列设备…” (Arrange Devices) to position speakers while playback is stopped.
5. Open “更多设置” (More Settings) to adjust each device’s volume, latency, or receiver name. Disconnect and reconnect a receiver after changing its name.

Requirements and sound

Mac requires macOS 14.2 or later. iPhone and iPad require iOS or iPadOS 17 or later. Keep devices on a trusted, usable local IP network and use built-in speakers. Multiple devices distribute a stereo source’s left and right channels; they do not create discrete surround channels.

If a device does not appear or audio stops

• Check local network permission and that the Mac has enabled connections. On networks that block device-to-device traffic, discovery or playback may fail.
• Check Mac system audio-recording permission, the source app’s playback, and each device’s volume. Protected content may not be available for capture.
• Return to the receiver app and reconnect if necessary. Disconnect headphones, Bluetooth, or AirPlay outputs before using the built-in speakers.
• If playback stutters, try a larger shared delay in More Settings and a more stable network. Delay can affect audio/video synchronization.
• For iPad Sidecar, begin receiving audio before returning to Sidecar. A USB cable alone is not a dedicated audio transport for this app.
