- ✅ Smaller download size
- ✅ Multiple startup options
- ✅ Cross-platform compatibility

## 🔧 First-Time Setup Process

When a user runs SafetyMaster Pro on their Mac for the first time:

1. **Security Check**: macOS may show "unidentified developer" warning
   - Solution: Right-click → Open, or System Preferences → Security & Privacy

2. **Python Detection**: App automatically finds Python installation
   - If missing: Shows clear installation instructions

3. **Dependency Installation**: Automatically installs required packages
   - Creates virtual environment for isolation
   - Downloads AI models if needed

4. **Camera Permissions**: Requests camera access
   - Shows system dialog for permission
   - Provides troubleshooting if denied

5. **Launch**: Opens web browser to http://localhost:8080

## 🛠️ Troubleshooting Common Issues

### Issue: "App can't be opened because it is from an unidentified developer"
**Solution:**
```bash
# Method 1: Right-click approach
1. Right-click "SafetyMaster Pro.app"
2. Select "Open" from menu
3. Click "Open" in security dialog

# Method 2: System Preferences

# The app will show this dialog with options:
1. Download from: https://www.python.org/downloads/macos/
2. Or install via Homebrew: brew install python3
3. Or install Xcode tools: xcode-select --install
```

### Issue: Camera access denied
**Solution:**
```bash
1. System Preferences → Security & Privacy → Camera
2. Enable checkbox for "SafetyMaster Pro"
3. Restart the application
```

### Issue: Dependencies fail to install
**Solution:**
```bash
# Manual installation in Terminal:

## 🎯 Best Practices for Distribution

### For IT Departments:
1. **Test on one Mac first** to verify compatibility
2. **Document Python installation** if needed company-wide
3. **Configure camera permissions** in MDM if available
4. **Use ZIP package** for easier deployment

### For Individual Users:
1. **Use the App Bundle** - simplest experience
2. **Follow security prompts** - normal for unsigned apps
3. **Grant camera permissions** when requested
4. **Check system requirements** before installation

### For Developers:
1. **Include both app bundle and ZIP** in distribution
2. **Provide clear README** with troubleshooting
3. **Test on different Mac models** if possible
4. **Consider code signing** for enterprise distribution

## 🔐 Security Considerations

### App Bundle Security:
- ⚠️ **Unsigned app**: Will trigger macOS security warnings
- ✅ **Safe to run**: Contains only Python scripts and AI models
- ✅ **No system modifications**: Runs in user space only
- ✅ **Local processing**: No data sent to external servers

### For Enterprise Distribution:
```bash
# Optional: Sign the app bundle (requires Apple Developer account)
codesign --deep --force --verify --verbose --sign "Developer ID Application: Your Name" "SafetyMaster Pro.app"

# Or: Add to enterprise whitelist
spctl --add "SafetyMaster Pro.app"
```

## 📈 Performance Expectations

| Mac Type | Expected FPS | AI Processing | Notes |
|----------|-------------|---------------|-------|
| M1/M2/M3 MacBook | 30-60 FPS | 20-30 FPS | Excellent performance |
| Intel MacBook Pro | 25-45 FPS | 15-25 FPS | Very good performance |
| Intel MacBook Air | 20-35 FPS | 10-20 FPS | Good performance |
| Older Intel Macs | 15-30 FPS | 8-15 FPS | Adequate performance |

## ✅ Final Compatibility Checklist

Before distributing to other Macs:

- [ ] Test app bundle on different Mac if available
- [ ] Verify all AI model files are included (26.4 MB total)
- [ ] Check that templates directory is present
- [ ] Confirm README.txt is included with instructions
- [ ] Test camera access on target Mac type
- [ ] Verify Python detection works
- [ ] Check web interface loads at localhost:8080

## 🎉 Summary
