Airfoil for Mac Release Notes

Initial Support for MacOS 26 (Tahoe)
Airfoil now has initial support for MacOS 26 (Tahoe), and will no longer warn at launch. However, there are currently two known issues with Tahoe which can result in lost audio.

    • Known issue with sample rate mismatches: If an application is playing audio to an external device whose sample rate does not match that of the system’s default output device, attempting to capture it will fail.

    • Known issue with lost audio from FaceTime and Phone: Attempting to capture audio from FaceTime or the new Phone app fails in certain setups.

With each of these bugs, silence will be heard, rather than the expected audio. Find more details, including workarounds, in our support article.

These bugs need to be corrected by Apple, in a future MacOS update. As such, you may wish to consider delaying your upgrade to Tahoe until a later date.

Two New Special Sources
Two new special sources have been added on MacOS 15 (Sequoia) and higher. The new “Spoken Content” special source replaces the previous “Text to Speech” special source, and captures audio from the “Accessibility” settings “Spoken Content” area, as well as from apps which play text-to-speech audio (triggered by the “Start Speaking” command in the “Speech” menu) via the system. The new “Notification Center” special source captures other audio which plays through the system’s Notification Center, such as alarm sounds produced by MacOS’s “Clock” app.

Full Support for MacOS 15 (Sequoia)
Airfoil now offers full support for MacOS 15 (Sequoia), with no known incompatibilities.

Preliminary Support for MacOS 15 (Sequoia) Betas
Airfoil will no longer warn every launch when run on MacOS 15 (Sequoia). There are no known issues on Sequoia at present, but do note that these betas remain in flux. To avoid problems, we always encourage users to stick with Apple’s official (non-beta) OS releases.

Return of the “Text to Speech” Special Source
The “Text to Speech” special source has returned, to capture speech audio from applications which do not directly play generated speech (typically triggered by the “Start Speaking” command in the “Speech” menu) via their own process.

If you’re running the latest version of Airfoil when you check for an update, the resulting information screen now provides a helpful “View Release Notes” button.
