Audio Hijack 4.5.4Full MacOS 26 Support

Released on October 29, 2025

Full Support for MacOS 26 (Tahoe)

Audio Hijack 4.5.3Initial MacOS 26 Support

Released on September 3, 2025

Initial Support for MacOS 26 (Tahoe)
Audio Hijack 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.
New “Notification Center” Special Source
On MacOS 15 (Sequoia) and higher, 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.
An issue where long session lists could jump unexpectedly while scrolling has been resolved.
When navigating Audio Hijack’s audio grid via VoiceOver, it once again says “dimmed” for blocks that are turned off. This fixes a regression introduced in 4.5.1.
Audio Hijack’s app icon has been modified slightly, to enable it to escape from the icon jail Apple implemented in MacOS 26 (Tahoe).
Audio Hijack 4.5.3 Is for MacOS 14.4 and Higher

Audio Hijack 4.5.1

Released on May 21, 2025

New “Spoken Content” Special Source
On MacOS 15 (Sequoia), the new “Spoken Content” special source replaces the previous “Text to Speech” special source. It captures audio from the “Accessibility” settings “Spoken Content” area, as well as from apps which play text-to-speech audio via the system (triggered by the “Start Speaking” command in the “Speech” menu).
Newly created presets once again enter edit mode when created, allowing their title to be edited immediately. This fixes a regression introduced in 4.4.5.
Saved presets in the “10-Band EQ” effect once again correctly show their name, rather than “Manual”, fixing a regression introduced in 4.5.0.
The “Transcribe” block no longer shows an error when the selected destination folder has been deleted. Instead, the folder is automatically re-created at the start of the session, matching the behavior of the “Recorder” block.
If an output device’s preferred stereo channels update while in use, Audio Hijack will now automatically start using the new channels, rather than requiring a session to be stopped and restarted.

Audio Hijack 4.4.2

Released on May 22, 2024

Corrections for Default Settings for VoIP apps in the New “Audio Device Selection” Section of the “Application” Block
This update fixes a critical issue where attempting to capture from a VoIP app like Zoom or Skype could result in no audio being recorded. Due to an incorrect migration of existing sessions from Audio Hijack 4.4.0 or earlier, setups where a VoIP app was playing to a non-default output would not see any audio.

Audio Hijack now correctly defaults the “Audio Device Selection” option to “Capture audio played to all output devices” for VoIP applications. Thanks to Jason Snell for the heads-up on this issue.
Audio Hijack 4.4.2 Is for MacOS 14.4 and Higher
This variant of Audio Hijack supports MacOS 14.4 and higher. On MacOS 11 through 14.3.1, a different variant is automatically used, with no action required on your part.

Audio Hijack 4.4.1

Released on May 14, 2024

Enhanced Audio Capture for “Application” Blocks via the New “Audio Device Selection” Section
The “Limit audio capture” setting previously found under the “Advanced” setting in “Application” blocks, has been transformed into a new and more powerful “Audio Device Selection” section.

These updated controls now offer more refinement over how audio is captured from applications, including channel-level fine-tuning. This is particularly useful for apps which can play audio output to multiple devices, such as “djay”, “Radiologik”, and our own “Farrago”.
To avoid poor performance on systems with many output devices, most audio capture via the “Application” block now defaults to capturing only that audio played to the system‘s default audio output device. Do note that when capturing from VoIP applications, like Zoom and Skype, Audio Hijack will continue to target audio sent to all output devices as before.

In nearly all instances, these default settings should capture exactly the audio expected. If adjustments are desired, the new “Audio Device Selection” section of the “Application” block can always be configured to get the exact audio desired.
If you’re running the latest version of Audio Hijack when you check for an update, the resulting information screen now provides a helpful “View Release Notes” button.
Capture of audio played to secondary devices by VOIP applications has been improved.
Elements in the LCD area of a session will no longer incorrectly overlap at small sizes.
It’s no longer incorrectly possible to start playback prematurely for in-progress recordings.

The “Session List” window will no longer incorrectly appear due to opening the “About” or “Quick Tour” windows.
The vestigal “ACE: Prioritize reliability over latency” hidden setting, previously found in the “Debugging” window, has now been properly excised.

Audio Hijack 4.4.0Requires MacOS 14.4 or Higher

Released on April 3, 2024

A Powerful New Audio Capture Backend
Audio Hijack now uses a new audio capture backend called Audio Routing Kit, or “ARK” for short. Thanks to ARK, Audio Hijack can be set up on a new Mac in seconds, with no restarts or passwords required.
New “System Audio Access” Permission
The “Permissions” window has been updated, with a new “System Audio Access” permission. This permission enables you to use Audio Hijack to record audio from applications you specify.
Standard User Accounts Welcome
Standard MacOS user accounts can now capture and record audio with Audio Hijack, without needing any help from an Administrator account.
Erroneous Microphone-In-Use Indicators, Begone!
Previously, when Audio Hijack was playing audio to a device that also has input channels, or capturing from any application on MacOS 14.2 and higher, MacOS would erroneously display its orange microphone-in-use indicator. With changes to Audio Hijack’s audio capture backend, that is no longer the case, and we’re very glad about it.
Audio Hijack’s “Application” block now provides a more powerful device-specific capture for complex setups. With the “Limit audio capture” setting in the “Advanced” section, it’s now possible to capture any combination of audio an application is sending, even when it’s playing to multiple devices.
The “System Audio” source, used to capture all audio playing on the Mac, has now been renamed “System-Wide Audio”.
The “Siri” special source has been updated to work as expected on all releases of MacOS 14 (Sonoma).
Audio devices which contain brackets in their name are now displayed correctly throughout Audio Hijack
Accessibility improvements have been made for the “Permissions” window.

The Recordings and Schedule tabs now feature "Delete Recording(s)" and "Delete Timer(s)" buttons respectively, to make it much more obvious how to delete these items.

The "Open URL" field is now only editable when the checkbox is on.
The text of the Ducking block has been updated in an attempt at greater clarity. Its functionality is unchanged.

Ducking now quickly fades audio in and out, rather than doing hard, instant adjustments.
Recorders which hit a File Limit will now correctly resume after either the Block or the Session is toggled off and back on.
A disabled timer could stop a recording currently being made by another timer. That is really silly, and now, it’s gone.
Variables in Recorder Block tags and file names are now properly expanded, to fix both omitted fields and issues with expansion.
When a Recorder Block has variables in multiple fields which refer to one another, this is now handled sensibly. As well, variables in Recorder Block tags can no longer incorrectly refer back to themselves.

Recorder presets now correctly save all settings and tags (excluding artwork).
Tooltips were sometimes lagging behind reality, but they've been given a speed boost.

Accessibility improvement: The "Hide Library" button (which hides the library from VoiceOver navigation, as well as visually) is now correctly labeled for VoiceOver.

Control-click an Audio Unit’s block to select the generic interface, if the plugin’s custom interface is not desired. This can be especially helpful for visually impaired users.
Output Device Blocks include a built-in monitor control for output volumes. Adjust this to lower the volume locally, without affecting your recording.
