## 🍎 **Available Packages**

### **Universal Installer (Recommended)**
```bash
# Auto-detects architecture and installs appropriate package
curl -fsSL https://raw.githubusercontent.com/aitbc/aitbc/main/packages/github/packages/macos-packages/install-macos-universal.sh | bash
```

### **Architecture-Specific Packages**

#### **Apple Silicon (M1/M2/M3)**
```bash
curl -fsSL https://raw.githubusercontent.com/aitbc/aitbc/main/packages/github/packages/macos-packages/aitbc-cli-0.1.0-arm64.pkg -o aitbc-cli.pkg
sudo installer -pkg aitbc-cli.pkg -target /
```

#### **Intel Macs**
```bash
curl -fsSL https://raw.githubusercontent.com/aitbc/aitbc/main/packages/github/packages/macos-packages/aitbc-cli-0.1.0-x86_64.pkg -o aitbc-cli.pkg
sudo installer -pkg aitbc-cli.pkg -target /
```

#### **Universal Binary**
```bash
curl -fsSL https://raw.githubusercontent.com/aitbc/aitbc/main/packages/github/packages/macos-packages/aitbc-cli-0.1.0-universal.pkg -o aitbc-cli.pkg
sudo installer -pkg aitbc-cli.pkg -target /
```

## 📦 **Package Files**

| Package | Architecture | Size | Description |
|---------|--------------|------|-------------|
| `aitbc-cli-0.1.0-arm64.pkg` | Apple Silicon | ~2KB | Demo package for M1/M2/M3 Macs |
| `aitbc-cli-0.1.0-x86_64.pkg` | Intel | ~2KB | Demo package for Intel Macs |
| `aitbc-cli-0.1.0-universal.pkg` | Universal | ~2KB | Demo package for all Macs |
| `aitbc-cli-0.1.0-demo.pkg` | Legacy | ~2KB | Original demo package |

## ⚠️ **Important Notes**

These are **demo packages** for demonstration purposes. They show:
- Package structure and installation process
- macOS integration (man pages, completion)
- Cross-platform distribution

For **full functionality**, use the Python-based installation:
```bash
curl -fsSL https://raw.githubusercontent.com/aitbc/aitbc/main/packages/github/install-macos.sh | bash
```

## ✅ **Verification**

### **Check Package Integrity**
```bash
sha256sum -c checksums.txt
```

### **Test Installation**
```bash
# After installation
aitbc --version
aitbc --help
```

## 🔄 **Future Production Packages**

When the full build system is ready, you'll get:
- **Real native executables** (~80MB each)
- **Code signing and notarization**
- **Automatic updates**
- **App Store distribution**

## 📚 **Documentation**

- **[Main Documentation](../README.md)** - Complete installation guide
- **[Migration Guide](../MACOS_MIGRATION_GUIDE.md)** - From .deb to native packages
- **[Build System](../DEBIAN_TO_MACOS_BUILD.md)** - Cross-compilation setup
