AppleScript & JXA Automation
Expert in AppleScript and JavaScript for Automation (JXA) for macOS system scripting.
Execution Methods
osascript -e 'tell application "Finder" to activate'
osascript script.scpt
osascript -l JavaScript -e 'Application("Finder").activate()'
osascript <<'EOF'
tell application "Safari"
make new document
set URL of document 1 to "https://example.com"
end tell
EOF
Common Patterns
Application Control
-- Activate app
tell application "Safari" to activate
-- Get frontmost app
tell application "System Events" to get name of first process whose frontmost is true
-- List windows
tell application "System Events"
tell process "Safari"
get name of every window
end tell
end tell
-- Click UI elements
tell application "System Events"
tell process "Safari"
click button 1 of window 1
end tell
end tell
File Operations
-- Open file
tell application "Finder"
open file "Macintosh HD:Users:user:file.txt"
end tell
-- Get selected files
tell application "Finder"
get selection as alias list
end tell
-- Create folder
tell application "Finder"
make new folder at desktop with properties {name:"New Folder"}
end tell
Notifications & Dialogs
-- Display notification
display notification "Task complete" with title "Script" sound name "default"
-- Dialog with buttons
display dialog "Continue?" buttons {"Cancel", "OK"} default button "OK"
-- Choose file
choose file with prompt "Select a file:"
-- Choose folder
choose folder with prompt "Select a folder:"
Shell Integration
-- Run shell command (use quoted form for safety!)
set userPath to "/path/with spaces"
do shell script "ls " & quoted form of userPath
-- Get command output
set result to do shell script "date '+%Y-%m-%d'"
-- Run with timeout
with timeout of 10 seconds
do shell script "long-running-command"
end timeout
JXA Examples
Application('Safari').activate()
Application('System Events').processes.whose({ frontmost: true })[0].name()
const app = Application.currentApplication()
app.includeStandardAdditions = true
app.displayDialog('Hello!', { buttons: ['OK'], defaultButton: 'OK' })
app.doShellScript('ls -la')
const finder = Application('Finder')
const desktop = finder.desktop
finder.make({ new: 'folder', at: desktop, withProperties: { name: 'Test' } })
Security Rules
ALWAYS use quoted form of for shell arguments:
-- BAD: injection risk
do shell script "echo " & userInput
-- GOOD: safe
do shell script "echo " & quoted form of userInput
NEVER execute with administrator privileges unless explicitly requested:
-- Requires user confirmation and password
do shell script "..." with administrator privileges
ASK user before accessing these sensitive apps:
- Keychain Access, 1Password, Bitwarden (passwords)
- Terminal, iTerm (can execute arbitrary commands)
- Mail, Messages (private communications)
- Banking/financial apps
- System Preferences/Settings
ASK user before these high-risk operations:
- Reading UI elements from apps (can expose sensitive data on screen)
- Sending keystrokes (
keystroke command)
- Clicking UI elements in unfamiliar apps
- Accessing clipboard contents
- Taking screenshots
NEVER do these without explicit user request:
keystroke passwords or sensitive data
- Read text from password fields
- Access browser cookies/sessions
- Send emails or messages on user's behalf
Debugging
sdef /Applications/Safari.app | head -50
open -a "Script Editor" /Applications/Safari.app
osascript -i
Common Issues
| Issue | Solution |
|---|
| "Not authorized" | Grant permissions in System Preferences → Privacy → Automation |
| "Application not found" | Use exact app name from /Applications |
| "Can't get window 1" | App may have no windows open |
| Timeout | Use with timeout of N seconds block |
| Quotes in strings | Escape with \" or use quoted form of |
