Automating System Settings

System Settings (formerly System Preferences) is a native macOS app with a rich Accessibility tree that works well with agent-native.

Overview

System Settings exposes excellent Accessibility support, making it ideal for automation. Common use cases include:

Configuring Wi-Fi networks
Adjusting display settings
Managing accessibility permissions
Toggling system features
Checking system information

Core workflow

The standard workflow for automating System Settings:

Open System Settings

agent-native open "System Settings"

See AXEngine.swift:65-119 for the app launching implementation.

Snapshot to find elements

agent-native snapshot "System Settings" -i

The -i flag shows only interactive elements (buttons, checkboxes, text fields). This keeps the output focused and manageable.See SnapshotCommand.swift:14-19 for the snapshot flags.

Interact using refs

agent-native click @n5

Every element in the snapshot has a ref (like @n5) that you can use for interactions.

Re-snapshot after navigation

agent-native snapshot "System Settings" -i

Important: Always re-snapshot after clicking navigation elements. The UI structure changes, and old refs become invalid.

Refs are invalidated when the UI structure changes. Always re-snapshot after navigation actions.

Example: Configuring Wi-Fi

Here’s a complete example of connecting to a Wi-Fi network:

#!/usr/bin/env bash
set -euo pipefail

# Open System Settings
agent-native open "System Settings"
sleep 1

# Find and click Wi-Fi in sidebar
agent-native snapshot "System Settings" -i > /tmp/snapshot.txt
WIFI_REF=$(grep -i "Wi-Fi" /tmp/snapshot.txt | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

if [[ -n "$WIFI_REF" ]]; then
  agent-native click "@$WIFI_REF"
  sleep 1
else
  echo "Wi-Fi not found in sidebar"
  exit 1
fi

# Re-snapshot to see Wi-Fi pane
agent-native snapshot "System Settings" -i > /tmp/wifi-pane.txt

# Find and click network name
NETWORK_NAME="MyWiFiNetwork"
NETWORK_REF=$(grep "$NETWORK_NAME" /tmp/wifi-pane.txt | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

if [[ -n "$NETWORK_REF" ]]; then
  agent-native click "@$NETWORK_REF"
  sleep 1
else
  echo "Network $NETWORK_NAME not found"
  exit 1
fi

# Enter password
agent-native snapshot "System Settings" -i > /tmp/password-dialog.txt
PASSWORD_REF=$(grep -i "Password" /tmp/password-dialog.txt | grep "AXTextField" | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

if [[ -n "$PASSWORD_REF" ]]; then
  agent-native fill "@$PASSWORD_REF" "MySecurePassword123"
  sleep 0.5
else
  echo "Password field not found"
  exit 1
fi

# Click Join button
JOIN_REF=$(grep -i "Join" /tmp/password-dialog.txt | grep "AXButton" | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

if [[ -n "$JOIN_REF" ]]; then
  agent-native click "@$JOIN_REF"
  echo "Successfully connected to $NETWORK_NAME"
else
  echo "Join button not found"
  exit 1
fi

See test/integration.sh:1-286 for more examples of automated testing patterns.

Common patterns

System Settings uses a sidebar for navigation. Items are typically AXStaticText or AXButton elements:

agent-native snapshot "System Settings" -i | grep -i "Wi-Fi\|Bluetooth\|Network"

AXStaticText "Wi-Fi" [ref=n12]
AXStaticText "Bluetooth" [ref=n13]
AXStaticText "Network" [ref=n14]

Using search

System Settings has a search field that can quickly navigate to settings:

# Find the search field
agent-native snapshot "System Settings" -i > /tmp/snap.txt
SEARCH_REF=$(grep -i "Search" /tmp/snap.txt | grep "AXTextField" | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

# Type search query
agent-native fill "@$SEARCH_REF" "Display"
sleep 0.5

# Press return to navigate
agent-native key "System Settings" return

Toggling checkboxes

Use check and uncheck commands, which are idempotent:

# Find checkbox
CHECKBOX_REF=$(agent-native snapshot "System Settings" -i | \
  grep -i "FileVault" | grep "AXCheckBox" | \
  grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

# Check it (won't fail if already checked)
agent-native check "@$CHECKBOX_REF"

# Or uncheck it
agent-native uncheck "@$CHECKBOX_REF"

See InteractionCommands.swift for implementation details.

Reading current values

Use the get command to read element states:

# Get current window title
agent-native get title "System Settings"

# Get text from an element
agent-native get text @n42

# Get input value
agent-native get value @n15

# Check if element is enabled
agent-native is enabled @n20

See GetCommand.swift and IsCommand.swift for details.

Example: Adjusting display settings

#!/usr/bin/env bash
set -euo pipefail

# Open System Settings and navigate to Displays
agent-native open "System Settings"
sleep 1

# Click Displays in sidebar
agent-native snapshot "System Settings" -i > /tmp/snap.txt
DISPLAY_REF=$(grep -i "Displays" /tmp/snap.txt | \
  grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

agent-native click "@$DISPLAY_REF"
sleep 1

# Re-snapshot to see Display settings
agent-native snapshot "System Settings" -i > /tmp/display.txt

# Find and adjust brightness slider (example)
BRIGHTNESS_REF=$(grep -i "Brightness" /tmp/display.txt | \
  grep "AXSlider" | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

if [[ -n "$BRIGHTNESS_REF" ]]; then
  # Get current value
  current=$(agent-native get value "@$BRIGHTNESS_REF")
  echo "Current brightness: $current"
  
  # Set new value (0.0 to 1.0)
  agent-native fill "@$BRIGHTNESS_REF" "0.75"
  echo "Set brightness to 75%"
fi

# Find Night Shift checkbox
NIGHT_SHIFT_REF=$(grep -i "Night Shift" /tmp/display.txt | \
  grep "AXCheckBox" | grep -o 'ref=n[0-9]*' | sed 's/ref=//' | head -1)

if [[ -n "$NIGHT_SHIFT_REF" ]]; then
  agent-native check "@$NIGHT_SHIFT_REF"
  echo "Enabled Night Shift"
fi

Example: Checking system information

#!/usr/bin/env bash

# Open System Settings
agent-native open "System Settings"
sleep 1

# Navigate to General > About
agent-native snapshot "System Settings" -i | grep -i "General"
# Click General, then About...

# Snapshot the About pane
agent-native snapshot "System Settings" -i > /tmp/about.txt

# Extract information
grep -i "macOS\|Version\|Chip\|Memory" /tmp/about.txt

Using JSON output

For programmatic access, use --json flag:

agent-native snapshot "System Settings" -i --json > snapshot.json

[
  {
    "ref": "n1",
    "role": "AXButton",
    "title": "Wi-Fi",
    "label": null,
    "value": null,
    "enabled": true,
    "actions": ["AXPress"],
    "depth": 2
  },
  {
    "ref": "n2",
    "role": "AXCheckBox",
    "title": "Show Wi-Fi status in menu bar",
    "label": null,
    "value": "1",
    "enabled": true,
    "actions": ["AXPress"],
    "depth": 3
  }
]

Parse with jq:

# Find Wi-Fi button ref
WIFI_REF=$(agent-native snapshot "System Settings" -i --json | \
  jq -r '.[] | select(.title == "Wi-Fi") | .ref')

echo "Wi-Fi ref: @$WIFI_REF"

# Click it
agent-native click "@$WIFI_REF"

See SnapshotCommand.swift:105-111 for JSON encoding implementation.

Filter-based commands

You can interact with elements by filter instead of refs:

# Click by title
agent-native click "System Settings" --title "Wi-Fi"

# Fill by label
agent-native fill "System Settings" "MyNetwork" --label "Network Name"

# Check by role and title
agent-native check "System Settings" --title "FileVault" --role AXCheckBox

This is useful for one-off commands, but refs are more reliable for multi-step workflows. See ElementResolver.swift:6-51 for filter resolution logic.

Best practices

Always use -i flag

The -i flag filters to interactive elements only, making snapshots much more readable:

agent-native snapshot "System Settings" -i

Re-snapshot after navigation

UI changes invalidate old refs. Always re-snapshot after clicking:

agent-native click @n5
agent-native snapshot "System Settings" -i

Add delays

System Settings animations take time. Add small delays:

agent-native click @n5
sleep 1
agent-native snapshot "System Settings" -i

Use search for speed

The search field is the fastest way to navigate:

agent-native fill @n1 "Display"
agent-native key "System Settings" return

Troubleshooting

Sidebar item not found

Problem: Can’t find the setting in the sidebar.Solutions:

Use the search field instead:

agent-native fill @n1 "Wi-Fi"
agent-native key "System Settings" return

Check if you need to expand a group first (e.g., General > About)
Try searching with different keywords

Ref not resolving

Problem: @n5 doesn’t resolve after navigation.Cause: Old refs are invalid after UI changes.Solution: Re-snapshot after each navigation:

agent-native click @n5
sleep 1
agent-native snapshot "System Settings" -i  # Get new refs

Permission dialogs

Problem: System Settings shows permission dialogs.Solutions:

Use wait to wait for dialogs:

agent-native wait "System Settings" --role AXSheet --timeout 5

Snapshot the dialog and interact with it:

agent-native snapshot "System Settings" -i
# Find "Allow" or "OK" button
agent-native click @n10

Elements not found in snapshot

Problem: Expected element doesn’t appear in snapshot.Solutions:

Remove -i flag to see full tree:

agent-native snapshot "System Settings"

Increase depth with -d flag:

agent-native snapshot "System Settings" -i -d 10

Use find to search:

agent-native find "System Settings" --title "Wi-Fi"
