## Choose the Right Version

### For Apple Silicon Macs (M1, M2, M3, M4)
**Use:** \`${APP_NAME}-${VERSION}-aarch64.dmg\`
- MacBook Air (2020 and later)
- MacBook Pro (2020 and later) 
- iMac (2021 and later)
- Mac Studio (all models)
- Mac Pro (2023 and later)
- Mac mini (2020 and later)

### For Intel Macs
**Use:** \`${APP_NAME}-${VERSION}-x86_64.dmg\`
- MacBook Air (2019 and earlier)
- MacBook Pro (2019 and earlier)
- iMac (2020 and earlier)
- iMac Pro (all models)
- Mac Pro (2019 and earlier)
- Mac mini (2018 and earlier)

## How to Check Your Mac's Architecture

1. Click the Apple menu → About This Mac
2. Look for "Processor" or "Chip":
   - If it says "Apple M1", "Apple M2", "Apple M3", etc. → Use **aarch64** version
   - If it says "Intel" → Use **x86_64** version

Or use Terminal:
\`\`\`bash
uname -m
# arm64 = Apple Silicon (use aarch64 DMG)
# x86_64 = Intel (use x86_64 DMG)
\`\`\`

## Installation Instructions

1. Download the correct DMG file for your Mac
2. Double-click the DMG file to mount it
3. Drag "file-explorer.app" to your Applications folder
4. Launch from Applications or Spotlight search

## Troubleshooting

If the app doesn't open:
1. Right-click the app → Open (to bypass Gatekeeper warnings)
2. Go to System Preferences → Security & Privacy → Allow apps downloaded from App Store and identified developers

## Support

For issues or questions, please check the project documentation.
