Summary

OpenClaw macOS app crashes immediately (SIGABRT / abort() called) after enabling Microphone (and/or Voice Wake). This happens on a Mac mini M4 which has no built-in microphone, so there may be no valid audio input device.

Disable Microphone permission for OpenClaw, and/or disable Voice Wake / voice features.
(If stuck in crash loop) defaults delete bot.molt.mac

Steps to reproduce

1. Install/Open OpenClaw.app on Mac mini.
2. Enable Microphone permission (or toggle Voice Wake / talk features).
3. App crashes immediately on startup / when starting VoiceWakeRuntime.

Expected behavior

App should not crash. If no mic input device is available, Voice Wake should disable itself or show an error and continue running.

Actual behavior

App aborts with an uncaught Objective‑C exception originating in AVFAudio when installing an audio tap.
