Why Automate Safari Configuration?

Common Use Cases

Enterprise Deployment: Setting up standardized homepage and security settings across corporate devices
Development Environment: Configuring Safari for testing and development workflows
Kiosk Mode: Setting up dedicated browsing stations with specific configurations
System Administration: Managing browser settings remotely or in bulk
User Onboarding: Automating browser setup for new employees

Benefits of Automation

Consistency: Ensure identical configurations across all systems
Efficiency: Reduce manual configuration time
Compliance: Meet corporate security and policy requirements
Scalability: Apply changes to hundreds of systems simultaneously

Basic Safari Configuration Script

Shell Script Approach

Here’s a comprehensive shell script for automating Safari configuration:

#!/bin/bash

# Quit Safari to ensure changes take effect
osascript -e 'tell application "Safari" to quit'
sleep 2

# Set homepage and window behavior using defaults
defaults write com.apple.Safari HomePage -string "https://infopercept.com"
defaults write com.apple.Safari NewWindowBehavior -int 0
defaults write com.apple.Safari NewTabBehavior -int 0

# Force preferences to reload
killall cfprefsd

# Reopen Safari
sleep 2
open -a Safari
sleep 3

# Use AppleScript to configure homepage in Safari Preferences
osascript <<EOF
tell application "System Events"
    tell process "Safari"
        delay 2
        keystroke "," using command down -- Open Preferences
        delay 2
        -- Navigate to Homepage field
        keystroke tab
        keystroke tab
        keystroke tab
        keystroke tab
        delay 1
        -- Select existing text and replace with homepage URL
        keystroke "a" using command down
        delay 0.5
        keystroke "https://infopercept.com"
        delay 0.5
        keystroke return
        -- Close Preferences
        keystroke "w" using command down
    end tell
end tell
EOF

echo "✅ Safari homepage successfully set to https://infopercept.com"

AppleScript-Only Approach

For a cleaner AppleScript-only implementation:

#!/usr/bin/osascript

-- Quit Safari to ensure preferences apply
tell application "Safari" to quit
delay 2

-- Set homepage and open behavior using shell commands
do shell script "defaults write com.apple.Safari HomePage -string 'https://infopercept.com'"
do shell script "defaults write com.apple.Safari NewWindowBehavior -int 0"
do shell script "defaults write com.apple.Safari NewTabBehavior -int 0"
do shell script "killall cfprefsd"

-- Open Safari
delay 2
tell application "Safari" to activate

return "Safari homepage successfully set to https://infopercept.com"

Troubleshooting and Validation

Validation Script

#!/bin/bash

# Safari Configuration Validation Script
# Verifies that Safari settings have been applied correctly

echo "🔍 Validating Safari configuration..."

# Function to check a setting
check_setting() {
    local key=$1
    local expected=$2
    local domain=${3:-com.apple.Safari}

    current=$(defaults read "$domain" "$key" 2>/dev/null)

    if [[ "$current" == "$expected" ]]; then
        echo "✅ $key: $current (correct)"
        return 0
    else
        echo "❌ $key: $current (expected: $expected)"
        return 1
    fi
}

# Check critical settings
echo "Checking Safari preferences..."

check_setting "HomePage" "https://infopercept.com"
check_setting "NewWindowBehavior" "0"
check_setting "NewTabBehavior" "0"
check_setting "AutoOpenSafeDownloads" "0"
check_setting "SendDoNotTrackHTTPHeader" "1"

# Check if Safari is configured to show the homepage
echo ""
echo "🏠 Homepage configuration:"
homepage=$(defaults read com.apple.Safari HomePage 2>/dev/null)
echo "Current homepage: $homepage"

# Check Safari version
echo ""
echo "ℹ️ Safari information:"
safari_version=$(osascript -e 'tell application "Safari" to version' 2>/dev/null)
echo "Safari version: $safari_version"

# Check if configuration profiles are installed
echo ""
echo "📋 Configuration profiles:"
profiles -P 2>/dev/null | grep -i safari || echo "No Safari configuration profiles found"

echo ""
echo "🎯 Validation completed"

Common Issues and Solutions

Issue: Settings Don’t Persist

# Force preferences to reload and persist
killall cfprefsd
defaults synchronize

Issue: AppleScript UI Automation Fails

# Enable accessibility permissions for Terminal/script
# Check System Preferences > Security & Privacy > Privacy > Accessibility

# Use Configuration Profiles for persistent settings
sudo profiles install -path safari_config.mobileconfig

Debugging Script

#!/bin/bash

# Safari Configuration Debug Script
# Helps diagnose configuration issues

echo "🔧 Safari Configuration Debug Information"
echo "========================================"

# Check Safari installation
if [[ -d "/Applications/Safari.app" ]]; then
    echo "✅ Safari is installed"
    safari_version=$(defaults read /Applications/Safari.app/Contents/Info.plist CFBundleShortVersionString)
    echo "   Version: $safari_version"
else
    echo "❌ Safari is not installed"
    exit 1
fi

# Check current user
echo ""
echo "👤 Current user: $(whoami)"
echo "   User ID: $(id -u)"

# Check Safari preferences

# Check system integrity
echo ""
echo "🛡️ System integrity:"

else
    echo "System Integrity Protection status unknown"
fi

# Check accessibility permissions
echo ""
echo "♿ Accessibility permissions:"

Best Practices

Security Considerations

Validate Scripts: Always test scripts in a controlled environment before deployment
User Permissions: Run with appropriate privileges (avoid unnecessary root access)
Input Validation: Validate all user inputs and file paths
Secure Distribution: Use secure channels for script distribution
Audit Logging: Maintain logs of configuration changes

Error Handling

#!/bin/bash

# Robust Safari Configuration with Error Handling

set -euo pipefail  # Exit on error, undefined vars, pipe failures

LOGFILE="/var/log/safari_config.log"
HOMEPAGE_URL="https://company.com"

# Logging function
log() {
    echo "$(date '+%Y-%m-%d %H:%M:%S'): $*" | tee -a "$LOGFILE"
}

# Error handler
error_exit() {
    log "ERROR: $1"
    exit 1
}

# Validation function
validate_url() {
    local url=$1
    if [[ ! "$url" =~ ^https?:// ]]; then
        error_exit "Invalid URL format: $url"
    fi
}

# Main configuration function
configure_safari() {
    log "Starting Safari configuration"

    validate_url "$HOMEPAGE_URL"

    # Quit Safari with error handling
    if ! osascript -e 'tell application "Safari" to quit' 2>/dev/null; then
        log "Safari was not running or failed to quit"
    fi

    sleep 2

    # Apply settings with error checking
    if ! defaults write com.apple.Safari HomePage -string "$HOMEPAGE_URL"; then
        error_exit "Failed to set homepage"
    fi

    if ! defaults write com.apple.Safari NewWindowBehavior -int 0; then
        error_exit "Failed to set new window behavior"
    fi

    # Force preferences reload
    killall cfprefsd || log "Warning: Failed to reload preferences daemon"

    log "Safari configuration completed successfully"
}

# Run main function
configure_safari

Testing Framework

#!/bin/bash

# Safari Configuration Test Suite

TEST_RESULTS=()

# Test function
run_test() {
    local test_name=$1
    local test_command=$2

    echo "Running test: $test_name"

    if eval "$test_command"; then
        echo "✅ PASS: $test_name"
        TEST_RESULTS+=("PASS: $test_name")
    else
        echo "❌ FAIL: $test_name"
        TEST_RESULTS+=("FAIL: $test_name")
    fi
}

# Test suite
echo "🧪 Safari Configuration Test Suite"
echo "================================="

# Results summary
echo ""
echo "📊 Test Results Summary:"
echo "======================="
for result in "${TEST_RESULTS[@]}"; do
    echo "$result"
done

# Count results
pass_count=$(printf '%s\n' "${TEST_RESULTS[@]}" | grep -c "PASS" || true)
fail_count=$(printf '%s\n' "${TEST_RESULTS[@]}" | grep -c "FAIL" || true)

echo ""
echo "Passed: $pass_count"
