The reason is: Audio I/O Overload and Real-Time thread priority conflicts caused by a synchronization failure between the browser's process management and the macOS 26 (Tahoe) CoreAudio engine during resource deallocation.

Error codes: HALS_OverloadMessage and vm_rtfault_records.

If you are using Google (Chrome) or Firefox, please:

  • Launch the browser with the --disable-features=AudioServiceSandbox flag to bypass the sandbox-related Exclave permission conflicts.
  • Ensure the system output sample rate is locked at 48,000 Hz in Audio MIDI Setup to prevent resampling jitter during process termination.
