Update to MacOS 15.1 for Helpful Audio Bug Fixes

On Monday, Apple shipped the first major update to MacOS 15 (Sequoia). In addition to the premiere of Apple Intelligence, MacOS 15.1 includes important audio-related bug fixes. Here’s a look at several improvements you can expect to find with our products once you’ve updated to MacOS 15.1:

Capture from iPhone Mirroring
Capturing audio from Apple’s new “iPhone Mirroring” application now works as expected.
For: Airfoil Audio Hijack Loopback Piezo SoundSource

Capture of audio from command-line interface (CLI) tools
Audio capture from command-line processes now works as expected. Whether you’re targeting the Terminal for a process like `mpv` or `say` or an app that uses a command-line utility under the hood, audio will once again be correctly captured
For: Airfoil Audio Hijack Loopback Piezo SoundSource

Correct muting with System-Wide Audio captures
After a System-Wide Audio capture has been initiated, apps launched will now always be properly muted.
For: Airfoil Audio Hijack

Greatly reduced CPU usage
Thanks to fixes in the Mac’s “CoreAudio” system, SoundSource now uses minimal processing power when no applications are playing audio.
For: SoundSource

Improvements for apps running in exclusive (“hog”) mode
Previously, if an app was hogging an audio device, attempting to work with it could cause all audio capture to fail. That is no longer the case.
For: SoundSource

Update Now
We have long advised taking it slow when upgrading to a major new version of MacOS (from MacOS 14 to MacOS 15, for instance). In the case of this smaller update from MacOS 15.0 to MacOS 15.1, though, we heartily recommend updating your Mac now. As always, we also recommend using the latest versions of our own products. Select Check for Updates from within the app to get those.
