Turn it on
- Settings → Notch → Volume and brightness bars.
- Off by default. Turn it on, then tap volume or brightness.
What you need
- Sonoma and Sequoia use an event tap. Tahoe remaps the keys so the system HUD never draws.
- Accessibility in Settings → Permissions makes hold-repeat extra reliable. You can skip it and still get single taps.
Noggin Lock’s shortcut, ⌃⌥G, is not swallowed by the volume handler. Noggin still locks and unlocks.
