AirPlay latency for gaming on a Mac
Updated 2026-10-06
By default, AirPlay from a Mac adds about 2000 ms of audio delay, too much for games. Lowering macOS's AirPlay buffer to 350 ms, and keeping the stream awake so it doesn't pause between sounds, gets game audio to about a third of a second behind. For competitive play, use the Mac's own speakers: on a MacBook Pro they report about 18 ms.
How much delay to expect
| Setting | Audio delay | For games |
|---|---|---|
| macOS default | 2000 ms | Unplayable for anything timing-based |
| Lagless Safe | 750 ms | Casual games, menus |
| Lagless Balanced | 500 ms | Turn-based and story games |
| Lagless Responsive | 350 ms | Most casual and single-player games |
Numbers are the delay the AirPlay output reports to macOS. 350 ms is the floor: macOS subtracts a fixed 250 ms from the setting, and the speaker needs about 70 ms of the remainder (why).
Two things that make games feel worse
- The buffer. The 2000 ms default is set by macOS, not your network.
- Stream pauses. AirPlay suspends the stream during silence. When the next sound plays, it has to reconnect, which costs about 370 ms on top. Games are full of short silences, so this happens constantly. Lagless's Keep Speaker Awake plays inaudible noise to prevent it.
Cloud gaming
An Apple Community user reports that GeForce Now was in sync after connecting the HomePod from inside the Music app, which suggests that route avoids the system buffer for them. Results may vary; lowering the system buffer works for every app.
Questions
Is 350 ms low enough for rhythm or competitive games?
No. A third of a second is noticeable in anything timing-critical. The Mac's built-in speakers reported 18 ms in our measurement on a MacBook Pro running macOS 15.7.4.
Does Wi-Fi quality matter?
Yes, for how low you can go. If audio crackles or drops at 350 ms, step up to Balanced.
