Script macOS apps via AppleScript/JXA: Mail, Calendar (EventKit attendees), Notes, Reminders, Finder (disk/file info), and Spotlight/mdfind (full-text and metadata search across the file system).
Control macOS system audio via osascript. Use when getting or setting system volume, toggling mute, listing audio input/output devices, or checking which device is the default output.
Automate Google Chrome with osascript/JXA. Use when listing/focusing/closing/navigating/reloading tabs, muting tabs, managing windows, executing JavaScript, scraping page content, extracting links, filling forms, reading localStorage/cookies/audio state, or reading Chrome history/bookmarks/downloads/extensions/profiles.
Read and write the macOS clipboard with full type support. Use when reading clipboard text, HTML, RTF, images, or file paths (Finder copy); writing rich content; detecting clipboard changes via changeCount; or intercepting content between copy and paste.
Read macOS app SQLite databases directly. Use when reading iMessage chat history, Chrome browsing history, Safari history, or any local app SQLite DB. Always copy the DB before querying — most apps lock the file while running.
Create and manage macOS LaunchAgents and LaunchDaemons. Use when setting up background automation, scheduled tasks, file watchers (WatchPaths), interval polling, or persistent daemons that survive logout or reboot.

System state queries via pmset, NSProcessInfo ObjC bridge, System Events, and defaults.
All scripts are pure Python — mix of subprocess shell and JXA ObjC bridge.
Battery percentage, charging state, and time remaining (MacBook only):
uv run scripts/battery.py
OS version, hostname, CPU count, RAM, username — via NSProcessInfo ObjC bridge:
uv run scripts/system-info.py
List, add, or remove apps that launch at login via System Events:
uv run scripts/login-items.py --list
uv run scripts/login-items.py --add /Applications/Spotify.app
uv run scripts/login-items.py --remove Spotify
Read macOS user defaults by domain and optional key — --export for full domain JSON:
uv run scripts/user-defaults.py com.apple.dock
uv run scripts/user-defaults.py com.apple.finder AppleShowAllFiles
uv run scripts/user-defaults.py NSGlobalDomain --export
uv run scripts/user-defaults.py --list-domains
| Tool | Use case |
|---|---|
pmset -g batt | Battery percentage, state, time remaining |
NSProcessInfo (JXA ObjC) | OS version string, hostname, CPU count, RAM |
| System Events login items | Add/remove startup apps |
defaults + plutil CLI | Read/write NSUserDefaults (Dock, Finder, any app) |
defaults Domainscom.apple.dock — Dock position, tile size, autohidecom.apple.finder — Finder view, hidden files (AppleShowAllFiles)NSGlobalDomain — Dark mode (AppleInterfaceStyle), key repeat, scroll direction
