+# CLAUDE.MD - AI Assistant Development Guide for zapret (MacOS Edition)
+
+## 🎯 Project Overview
+
+**zapret** is a DPI (Deep Packet Inspection) circumvention tool that has been **fully refactored for MacOS** with native support for both **Intel (x86_64)** and **Apple Silicon (ARM64)** architectures.
+
+### Core Purpose
+- Bypass DPI-based censorship and network filtering
+- Provide transparent HTTP/HTTPS proxy capabilities
+- Support both Linux and **MacOS (Darwin)** systems
+- Native MacOS integration with PF (Packet Filter) and launchd
+
+### Critical Design Principle
+⚠️ **IMPORTANT**: macOS is **NOT BSD**! While it shares some BSD heritage, it is a unique hybrid system (XNU kernel = Mach + BSD + Apple components). This project correctly treats Darwin as a distinct platform with its own requirements.
+

+## 🏗️ Architecture: MacOS Support
+
+### Supported Architectures
+1. **x86_64** (Intel Macs)
+   - Target: `x86_64-apple-macos<version>`
+   - Minimum: macOS 10.8 (Mountain Lion)
+   - Recommended: macOS 11.0+ (Big Sur)
+
+2. **ARM64** (Apple Silicon: M1, M2, M3+)
+   - Target: `arm64-apple-macos<version>`
+   - Minimum: macOS 11.0 (Big Sur)
+   - Native ARM64 optimization
+
+3. **Universal Binaries**
+   - Single binary containing both architectures
+   - Automatic selection at runtime
+   - Best for distribution
+
+### MacOS-Specific Components
+
+#### Build System (Makefile)
+```makefile
+# Key variables
+DIRS_MAC := tpws ip2net mdig  # MacOS-compatible components
+MACOS_TARGET                  # Architecture target (auto-detected)
+MACOS_VERSION                 # MacOS version (auto-detected)
+IS_MACOS                      # Darwin detection flag
+```
+
+**New Makefile Targets for MacOS:**
+- `make mac` - Build for current architecture (auto-detected)
+- `make mac-universal` - Build universal binary (both architectures)
+- `make mac-auto` - Auto-detect and build
+- `make mac-info` - Display build information
+- `make mac-clean` - Clean MacOS-specific builds
+
+#### Architecture Detection Script
+**Location:** `scripts/macos_arch_detect.sh`
+
+**Functions:**
+- `detect` - Detect current architecture
+- `info` - Display system information
+- `check` - Verify build readiness
+- `build` - Build for current architecture
+- `universal` - Build universal binary
+- `version <ver>` - Set MacOS version target
+
+**Usage:**
+```bash
+./scripts/macos_arch_detect.sh detect
+./scripts/macos_arch_detect.sh info
+./scripts/macos_arch_detect.sh build
+./scripts/macos_arch_detect.sh universal
+```
+
+#### Testing Script
+**Location:** `scripts/test_macos_arch.sh`
+
+Performs comprehensive system testing:
+- System information gathering
+- Architecture detection validation
+- Build tools verification
+- Compilation test
+- MacOS-specific feature checks
+
+## 🔧 Development Workflow for Claude
+
+### When Making Changes
+
+1. **Architecture Awareness**
+   - Always test on both x86_64 and ARM64 if possible
+   - Use universal binary builds for distribution
+   - Respect architecture-specific optimizations
+
+2. **MacOS vs BSD vs Linux**
+   - **NEVER** assume BSD compatibility
+   - **ALWAYS** use Darwin-specific checks
+   - **PREFER** MacOS-native APIs and tools
+
+3. **Build System**
+   - Modify component Makefiles in `tpws/`, `ip2net/`, `mdig/`
+   - Update main `Makefile` for cross-component changes
+   - Test with `make mac` and `make mac-universal`
+
+4. **Testing Protocol**
+   ```bash
+   # Step 1: Clean build
+   make mac-clean
+
+   # Step 2: Build current architecture
+   make mac
+
+   # Step 3: Test functionality
+   ./scripts/test_macos_arch.sh
+
+   # Step 4: Build universal binary
+   make mac-universal
+
+   # Step 5: Verify installation
+   ./install_macos.sh info
+   ```
+
+### Key Files to Modify
+
+#### For Build System Changes
+- `Makefile` - Main build orchestration
+- `tpws/Makefile` - Transparent proxy build
+- `ip2net/Makefile` - IP tools build
+- `mdig/Makefile` - DNS tools build
+- `scripts/macos_arch_detect.sh` - Architecture management
+
+#### For Installation Changes
+- `install_macos.sh` - MacOS installer
+- `uninstall_macos.sh` - MacOS uninstaller
+- `install_bin.sh` - Binary installation (cross-platform)
+
+#### For Service Management
+- `init.d/macos/zapret` - launchd service script
+- `init.d/macos/zapret.plist` - launchd configuration
+
+#### For Documentation
+- `CLAUDE.MD` - This file (AI development guide)
+- `TODO` - Task tracking
+- `README_MACOS_FINAL.md` - Comprehensive MacOS guide
+- `docs/MACOS_VS_BSD.md` - Critical Darwin vs BSD differences
+

+
+## ⚠️ Important Constraints
+
+### What NOT to Do
+
+❌ **Do NOT treat macOS as BSD**
+- Different system calls
+- Different networking stack
+- Different firewall (PF with Apple modifications)
+- Different service management (launchd, not rc)
+
+❌ **Do NOT assume Linux compatibility**
+- No iptables (use PF instead)
+- No systemd (use launchd instead)
+- No /proc filesystem
+- Different socket behavior
+
+❌ **Do NOT ignore architecture differences**
+- x86_64 and ARM64 have different optimizations
+- Endianness may differ in edge cases
+- System libraries may vary
+
+❌ **Do NOT skip testing**
+- Always run `./scripts/test_macos_arch.sh`
+- Always test both architectures when possible
+- Always verify installation and uninstallation
+
+### Security Considerations
+
+🔒 **System Integrity Protection (SIP)**
+- Some operations require SIP awareness
+- Never instruct users to disable SIP permanently
+- Prefer SIP-compatible solutions
+
+🔒 **Code Signing**
+- Binaries may need signing for distribution
+- Respect notarization requirements
+- Document signing requirements
+
+🔒 **Permissions**
+- Use appropriate file ownership (root:wheel)
+- Respect privilege separation
+- Document permission requirements
