## System Requirements
- macOS 10.14 (Mojave) or later
- Python 3.8 or later (will be installed automatically if missing)
- Camera/webcam connected
- At least 2GB RAM
- 1GB free disk space

## Installation Instructions

### Method 1: Double-Click (Easiest)
1. Double-click "SafetyMaster Pro.app"
2. If prompted about security, go to System Preferences > Security & Privacy and click "Open Anyway"
3. Grant camera permissions when requested
4. The app will open in your web browser

### Method 2: Right-Click Open (If security blocked)
1. Right-click "SafetyMaster Pro.app"
2. Select "Open" from the context menu
3. Click "Open" in the security dialog
4. Grant camera permissions when requested

## First Run Setup
1. The app will automatically install Python dependencies
2. Grant camera access when prompted
3. The web interface will open at http://localhost:8080
4. Click "Start Monitoring" to begin safety detection

## Troubleshooting

### "App can't be opened because it is from an unidentified developer"
- Right-click the app and select "Open"
- Or go to System Preferences > Security & Privacy > General and click "Open Anyway"

### Python Not Found
- Install Python from https://www.python.org/downloads/macos/
- Or install Homebrew and run: brew install python3

### Camera Access Denied
- Go to System Preferences > Security & Privacy > Camera
- Enable camera access for SafetyMaster Pro

### Port Already in Use
- Make sure no other SafetyMaster Pro instances are running
- Or restart your Mac to free up the port

## Features
- Real-time PPE detection (hard hats, safety vests, masks)
- Web-based dashboard with statistics
- Violation tracking and alerts
- High-performance AI processing (30+ FPS)
- Cross-platform compatibility

## Support
For issues or questions, check the included documentation or visit the project repository.
