The least dull thing on your Mac

DullNotch turns the MacBook notch into a Liquid Glass panel for music, widgets, a per-app mixer and a file converter. While it is closed, it shows what is in progress.

This one works. Point at the notch to open it, or tap it.

What the open notch is made of

Four layers, from the content you see down to your desktop. Point at one to pick it out.

Widgets: Music, calendar, weather: whatever you put in the home.
Dimming floor: A black band under the camera fades into the glass. No seam, and text stays readable on any wallpaper.
Liquid Glass: Real system glass on macOS 26. It bends whatever is behind it, live.
Your desktop: Never captured: the system draws the glass over it.

Five things the notch never did

Everything from Boring Notch is still here: music, calendar, shelf, HUDs. These are new.

One fader for every app

Turn the call up and the music down. Each app playing sound gets its own fader, from 0 to 150%. There is no audio driver to install.

A home you arrange yourself

Drag widgets onto a live preview of the notch: music, calendar, weather, Bluetooth battery, system monitor, AI usage, mirror or a quote. One large and two small fit, and the notch resizes around them.

Drop a file, pick a format

Images, text documents and PDFs convert on your Mac. Nothing is uploaded.

See when Claude Code is done

Claude's mascot types or hammers on the closed notch while Claude Code works, then takes a coffee break when it finishes. One click in Settings connects it.

Your iPhone as a remote

Start MacRemote from the notch and scan the QR code. Volume, media, keyboard and touchpad work from Safari on your phone, with nothing to install on it.

Liquid Glass: Real system glass on macOS 26. One slider goes from classic black to clear.
Progress on the closed notch: A Clock timer, a download, charging or what is left of your AI plan, one at a time.
HUD colors: Volume, brightness and keyboard HUDs in any color, with a live preview.
Spotify everywhere: Shows what plays on your phone, speakers or TV. Works with Spotify Free, through Last.fm.
Weather: The sky of the current condition, gently animated. No API key.
Bluetooth battery: AirPods and Beats show left, right and case.
System monitor: CPU, memory, GPU and temperatures with a graph of the last two minutes.
AI usage: Your Claude or Codex limits as two rings: five hours and the week.

It costs almost nothing to run

Notch closed, nothing in progress	0.0% of a CPU core
A timer running on the closed notch	Under 1%
Claude's mascot at work	About 2%
Liquid Glass	Drawn by the system: no screen capture

Measured on a Release build on our Mac. Yours may differ.

Install it in a minute

Download the latest release

Or build it from source with Xcode 26.

Download DullNotch.zip from the latest release and unzip it.
Drag DullNotch.app into Applications.
If Boring Notch is installed, quit it first: both apps use the same identifier.
Open it, then allow it in System Settings, under Privacy & Security, with Open Anyway.
The app is not notarized by Apple, so macOS blocks the first launch. This command does the same:

xattr -dr com.apple.quarantine /Applications/DullNotch.app
