How to enable exclusive mode on macOS

Last updated June 2026

Exclusive mode (also called hog mode) lets a music player take sole control of your DAC, bypassing the macOS Core Audio mixer so audio reaches the DAC unaltered. It’s the key step for bit-perfect playback: without it, macOS resamples and mixes everything to one shared output rate. Here’s how to turn it on and confirm it’s working.

Steps

  1. Connect your DAC and select it as the output device. Exclusive mode applies to external/USB DACs, not AirPlay or aggregate system outputs.
  2. Enable Exclusive Mode (hog mode) in your player’s audio settings. In BitMuse, it’s a single toggle. macOS will route other system sounds elsewhere while it’s active.
  3. Turn on integer mode and let the player match the device sample rate to each file, so nothing is resampled or converted to floating point on the way out.
  4. Set volume to 0 dB (or use the DAC’s hardware volume). Any software volume change scales the samples and breaks bit-perfect output.
  5. Verify the signal path. A good player shows a live indicator confirming exclusive mode is active, the rate matches, and no processing is applied.

Why exclusive mode matters

By default, macOS sends every app’s audio through a shared mixer that resamples to a common rate and applies system volume. That’s convenient but not bit-perfect. Exclusive mode removes the mixer from the path entirely, so the digital samples in your file reach the DAC exactly as stored.

How to confirm it actually worked

Enabling a toggle isn’t proof. The reliable check is a real-time signal path that shows exclusive mode active, the device rate equal to the file rate, integer output, and no resampling or volume scaling. BitMuse displays this live and only reports bit-perfect when every condition is met — so you’re verifying, not assuming.

FAQ

Do I need a DAC for exclusive mode?

Exclusive mode is most meaningful with an external/USB DAC. The Mac’s built-in output can play cleanly, but exclusive mode, integer mode and native DSD are unlocked by a DAC.

Will other apps still make sound in exclusive mode?

While a device is held in exclusive mode, macOS routes other system audio elsewhere. Turn it off to share the device again.
