DisplayHelp 0.6.3 (95)

Released 2026-09-20. Feedback, bug reports and suggestions are welcome. macOS 14 or later; universal Apple Silicon and Intel installer. Existing profiles remain compatible.

What changed

  • Output Volume beneath Screen Layout follows the active macOS audio device, including built-in speakers, with volume and mute controls when supported.
  • Native CoreAudio notifications refresh the active device and its volume/mute when changed in macOS or another app. Device switches prevent stale controls from writing to the newly selected device.
  • Devices without writable software volume show an explanation. External monitor DDC volume is separately labeled Monitor Volume.
  • Master-volume controls are preferred. Channel-based devices preserve relative balance; failed writes/readback attempt to restore prior channel values. An all-zero channel set has no recoverable balance and starts evenly when raised.
  • Copy Diagnostics distinguishes system output volume/mute from monitor volume. Output Volume and mute are not saved in profiles; existing saved audio routing and DDC volume retain their behavior.
  • All current UI screenshots and Word/PDF guides were refreshed, including built-in speaker and unsupported-output examples. The locally hosted video thumbnail still links to the earlier-interface video.

Validation

  • 139 Swift tests passed without compiler warnings, covering channel balance, invalid levels, write/readback failure recovery, unsupported outputs, stale-device writes and unchanged stored preferences.
  • Live built-in speaker validation on this Mac verified volume and mute writes/readback and received three native audio-change callbacks. Original volume, mute and output selection were restored afterward.
  • Local upgrade to 0.6.3 (95) succeeded; the running installed executable matches the built executable and the package receipt reports 0.6.3.95.
  • The universal release installer is Developer ID signed, notarized by Apple, stapled and accepted by Gatekeeper.

The live audio check covered this Mac’s built-in speakers; behavior on other USB, HDMI and third-party audio devices depends on their exposed controls. See the earlier display hardware validation and Identify Displays validation for those features.

All 34 app screenshots use current production controls and isolated sample data. No real audio/display settings or user data were changed to stage them; only the harmless Custom Fixes demo was executed. See the screenshot gallery.
