Version

• App: 2026.2.12 (build 9500)
• OS: macOS 26.2 (25C56), Apple Silicon (Mac16,11 — Mac mini M4 Pro)

Description

The macOS app crashes immediately on launch (~0.23s after procLaunch) when no audio input device (e.g. AirPods, headset, external mic) is connected. The Mac mini M4 Pro has no built-in microphone.

Connecting AirPods before launching resolves the issue. The app should gracefully disable voice wake when no audio input is available, not abort.

Crash Stack

EXC_CRASH (SIGABRT) — abort() called

AVAudioEngineImpl::InstallTapOnNode() → NSException (+[NSException raise:format:])
-[AVAudioNode installTapOnBus:bufferSize:format:block:]
VoiceWakeRuntime.start(with:)
VoiceWakeRuntime.refresh(state:)
closure #2 in AppState.init(preview:)

The uncaught ObjC exception from AVAudioEngine propagates through objc_exception_throw → __cxa_throw → __cxxabiv1::failed_throw → std::__terminate → abort().

Expected Behaviour

App should launch normally without an audio device, disabling voice wake gracefully until a device becomes available (e.g. observing AVAudioSession.routeChangeNotification).

Workaround

Connect an audio input device before launching.
