CommandNotch

A drop-down terminal for macOS that lives in the notch area.

CommandNotch is a notch-native terminal overlay for macOS. It gives you a fast shell without switching spaces, keeping a full Terminal window open, or breaking your flow. Open it with a hotkey, drop into a shell, then get out of the way just as quickly.

The current Xcode target and bundle name are still CommandNotch, but the project is being presented publicly as CommandNotch.

Why CommandNotch

• You want a terminal that is always one shortcut away.
• You like the idea of a terminal living in the menu bar / notch area instead of a full window.
• You work across multiple displays and want each screen to keep its own notch state.
• You want lightweight workspaces, detachable tabs, and shell access without giving up native macOS feel.

Features

• Native macOS notch overlay with open and closed states.
• Fast shell sessions powered by SwiftTerm and a local login shell.
• Multiple tabs with hotkeys for new, close, next, previous, and direct tab switching.
• Workspace support, including shared workspaces across screens.
• Multi-display awareness with per-screen assignment and presentation state.
• Detachable tabs that can pop out into standalone terminal windows.
• Terminal themes: Classic, Xterm, Solarized Dark, Dracula, and Nord.
• Configurable terminal size presets with optional hotkeys.
• Hover-to-open behavior and animation tuning.
• Launch at login support.
• Global toggle hotkey and notch-scoped shortcut handling.
• Terminal-friendly macOS key behavior for Command+Arrow, Option+Arrow, Command+Backspace, and Command+L.

Getting Started

Requirements

• macOS 14 or later
• Xcode 16 or later
• Homebrew xcodegen
• Homebrew create-dmg for release .dmg packaging

Build

cd CommandNotch
xcodegen generate --spec project.yml
open CommandNotch.xcodeproj

Or from the command line:

cd CommandNotch
xcodegen generate --spec project.yml
DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer \
  xcodebuild build -project CommandNotch.xcodeproj -scheme CommandNotch -destination 'platform=macOS'

Build a release .dmg

Use create-dmg to build the styled Finder installer window with the usual drag-to-Applications layout.

Install the packaging dependency once:

brew install create-dmg

Then build from the app/ directory:

./scripts/build-release-dmg.sh

That produces:

• releases/CommandNotch YYYY-MM-DD HH-MM-SS/CommandNotch.app
• releases/CommandNotch YYYY-MM-DD HH-MM-SS/CommandNotch.dmg

Notes:

• The script regenerates the Xcode project, archives the Release build, then packages the archived app into a styled .dmg.
• The archive is written to /tmp and is only used as the source for the exported .app.
• If you want a distributable build signed with a specific identity, make sure your Xcode signing settings are configured before running the archive step.
