For macOS compatibility, modify `index.js`:\n\n```javascript\n// Detect platform and set appropriate chrome path\nfunction getChromePath() {\n const platform = process.platform;\n \n switch(platform) {\n case 'linux':\n return '/usr/bin/chromium-browser';\n case 'darwin': // macOS\n // Try multiple possible paths\n const macPaths = [\n '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',\n '/Applications/Chromium.app/Contents/MacOS/Chromium',\n '/opt/homebrew/bin/chromium'\n ];\n \n for (const path of macPaths) {\n if (require('fs').existsSync(path)) {\n return path;\n }\n }\n throw new Error('Chrome/Chromium not found on macOS');\n case 'win32':\n return 'C:\\\\Program Files\\\\Google\\\\Chrome\\\\Application\\\\chrome.exe';\n default:\n throw new Error(`Unsupported platform: ${platform}`);\n }\n}\n\n// Update startChromium method\nasync startChromium() {\n const chromePath = getChromePath();\n const platform = process.platform;\n \n // Platform-specific arguments\n const baseArgs = [\n '--headless',\n '--disable-extensions',\n '--disable-plugins',\n `--remote-debugging-port=${debuggingPort}`,\n '--no-first-run',\n '--disable-gpu',\n '--window-size=1280,720'\n ];\n \n // Add Linux-specific sandbox flags\n if (platform === 'linux') {\n baseArgs.push('--no-sandbox', '--disable-setuid-sandbox');\n }\n \n // Add macOS-specific flags if needed\n if (platform === 'darwin') {\n baseArgs.push('--disable-dev-shm-usage');\n }\n \n chromiumProcess = spawn(chromePath, baseArgs);\n // ... rest of method\n}\n```\n\n### **macOS-Specific Issues & Solutions**\n\n#### **1. \"Chromium is damaged\" Error**\n```bash\n# Remove quarantine flag if downloading manually\nsudo xattr -r -d com.apple.quarantine /Applications/Chromium.app\n\n# Or install via Homebrew with no-quarantine flag\nbrew install chromium --no-quarantine\n```\n\n#### **2. Chrome vs Chromium Choice**\n```bash\n# Option 1: Use Google Chrome (recommended)\n# Download from: https://www.google.com/chrome/\n# Path: /Applications/Google Chrome.app/Contents/MacOS/Google Chrome\n\n# Option 2: Use Chromium via Homebrew\nbrew install chromium --no-quarantine\n# Path: /opt/homebrew/bin/chromium\n```\n\n#### **3. Permission Issues**\n```bash\n# Ensure Chrome has required permissions\n# System Preferences > Security & Privacy > Privacy tab\n# Grant Camera, Microphone access if needed for specific use cases\n```\n\n### **Testing Cross-Platform Compatibility**\n\n#### **Quick Platform Detection Test**\n```bash\nnode -e \"\nconsole.log('Platform:', process.platform);\nconsole.log('Architecture:', process.arch);\nconst fs = require('fs');\n\nconst paths = {\n linux: '/usr/bin/chromium-browser',\n darwin: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',\n win32: 'C:\\\\\\\\Program Files\\\\\\\\Google\\\\\\\\Chrome\\\\\\\\Application\\\\\\\\chrome.exe'\n};\n\nconst chromePath = paths[process.platform];\nconsole.log('Expected Chrome path:', chromePath);\nconsole.log('Chrome exists:', fs.existsSync(chromePath));\n\"\n```\n\n#### **Cross-Platform MCP Test**\n```bash\n# Test basic functionality across platforms\necho '{\\\"jsonrpc\\\":\\\"2.0\\\",\\\"id\\\":1,\\\"method\\\":\\\"tools/call\\\",\\\"params\\\":{\\\"name\\\":\\\"evaluate\\\",\\\"arguments\\\":{\\\"script\\\":\\\"navigator.platform\\\"}}}' | node index.js\n\n# Should return the current platform\n```\n\n### **Windows ARM64 Considerations** \nWhile untested, Windows ARM64 support would need:\n\n```javascript\n// Windows-specific chrome path detection\ncase 'win32':\n const winPaths = [\n 'C:\\\\Program Files\\\\Google\\\\Chrome\\\\Application\\\\chrome.exe',\n 'C:\\\\Program Files (x86)\\\\Google\\\\Chrome\\\\Application\\\\chrome.exe',\n process.env.LOCALAPPDATA + '\\\\Google\\\\Chrome\\\\Application\\\\chrome.exe'\n ];\n // Similar path checking logic...\n```\n\n### **Performance Differences**\n\n| Platform | Startup Time | Memory Usage | Notes |\n|----------|--------------|--------------|--------|\n| **Linux ARM64 (Pi 4)** | ~3-4s | ~150MB | Optimized, well-tested |\n| **macOS Apple Silicon** | ~2-3s | ~200MB | Faster CPU, more memory |\n| **Windows ARM64** | Unknown | Unknown | Would depend on hardware |\n\n### **Contribution Needed**\n\n**We welcome contributions for full cross-platform support!**\n\n- **macOS testers**: Test the proposed changes on Apple Silicon\n- **Windows ARM64**: Test on Surface Pro X or similar devices \n- **Performance optimization**: Platform-specific optimizations\n- **Installation scripts**: Automated setup for each platform\n\n---\n\n## Claude CLI Integration\n\n### Prerequisites\n```bash\n# Install Claude Code CLI if you haven't already\nnpm install -g @anthropic-ai/claude-code\n```\n\n### Add to Claude CLI\n```bash\n# From the project directory after cloning\nclaude mcp add chromium-arm64 \"$(pwd)/mcp-wrapper.sh\" --scope user\n```\n\n### Verify Connection\n```bash\nclaude mcp list\n# Should show: chromium-arm64: /path/to/mcp-wrapper.sh - ✓ Connected\n```\n\n### ⚠️ Important: Restart Claude After Adding\n**You MUST start a new Claude session after adding the MCP server:**\n```bash\n# Exit current session if in one\nexit\n# Start fresh session\nclaude\n```\n\n### Using in Claude CLI\n\n**Ask Claude to use the chromium-arm64 tools:**\n```\nList available MCP servers and use chromium-arm64 to navigate to https://example.com\n\nTake a screenshot using the chromium-arm64 tool\n\nUse chromium-arm64 to click the button with selector #submit\n\nFill the email field using chromium-arm64 with test@example.com\n```\n\n**Be explicit to avoid Playwright/Puppeteer:**\n- \"Use chromium-arm64 to navigate...\"\n- \"Using the chromium-arm64 tool, take a screenshot\"\n- \"Open a browser\" (might try broken Playwright)\n- \"Take a screenshot\" (might try broken Puppeteer)\n\n### Success Example\n\nWhen working correctly, you'll see:\n```\nYou: Use chromium-arm64 to navigate to https://httpbin.org/json and show me what you see\n\nClaude: I'll navigate to https://httpbin.org/json using the chromium-arm64 tool.\n\n[Uses chromium-arm64.navigate tool]\n\nThe page displays a JSON object with a slideshow structure containing:\n- Author: \"Yours Truly\"\n- Date: \"date of publication\"\n- Title: \"Sample Slide Show\"\n...\n```\n\n## Usage Examples\n\n### Python API\n```python\nimport simple_browser\n\n# Navigate to any website\nresult = simple_browser.browser_navigate(\"https://example.com\")\nprint(result) # \"Successfully navigated to https://example.com\"\n\n# Take a screenshot\nscreenshot = simple_browser.browser_screenshot(\"homepage.png\")\nprint(screenshot) # \"Screenshot saved to /tmp/homepage.png\"\n\n# Execute JavaScript\ntitle = simple_browser.browser_evaluate(\"document.title\")\nprint(title) # Website title\n\n# Extract page content\ncontent = simple_browser.browser_get_content(\"text\")\nprint(content[:100]) # First 100 chars of page text\n```\n\n### MCP Tools (via Claude Code)\nOnce configured, use these tools directly in Claude Code:\n- `navigate` - Go to URLs\n- `screenshot` - Capture page images\n- `click` - Click elements by CSS selector\n- `fill` - Fill form fields\n- `evaluate` - Execute JavaScript\n- `get_content` - Extract page HTML/text\n- `close_browser` - Clean shutdown\n\n## 🎯 Key Use Cases\n\n### 🧪 **For Testing & QA Teams**\n- End-to-end SaaS testing with autonomous AI agents\n- Visual regression detection and cross-device compatibility\n- 24/7 continuous validation on budget hardware\n\n### 🚀 **For Startups & Makers** \n- Complete $480 AI development setup (see [Raspberry Pi Guide](README-RASPBERRY-PI.md))\n- No-code SaaS development with AI-powered testing\n- Competitive analysis and market research automation\n\n### 🛠️ **For DevOps & Developers**\n- CI/CD integration with comprehensive audit tools\n- Performance benchmarking and accessibility testing\n- Advanced debugging with console/network monitoring\n\n*📖 Full examples and detailed guides available in the [specialized documentation](#-documentation--specialized-guides).*\n\n---\n\n## 🏗️ Architecture\n\n```mermaid\ngraph TB\n A[Claude Code] --> B[MCP Protocol]\n B --> C[ARM64 Browser Server]\n C --> D[System Chromium]\n D --> E[Web Pages]\n \n F[Python Tools] --> C\n G[Direct CLI] --> C\n```\n\n## 🔧 Troubleshooting & Advanced Usage\n\nFor detailed troubleshooting guides, debugging tools, and advanced configuration:\n\n### 📖 Quick References\n- **Common Issues**: See [Technical Documentation →](README-TECHNICAL.md#-common-debugging-scenarios) \n- **Performance Tuning**: See [Technical Documentation →](README-TECHNICAL.md#-performance-benchmarks)\n- **Cross-Platform Setup**: See [Technical Documentation →](README-TECHNICAL.md#-cross-platform-arm64-compatibility)\n- **Complete Hardware Setup**: See [Raspberry Pi Guide →](README-RASPBERRY-PI.md#-complete-startup-ai-setup---under-500)\n\n### Quick Fixes\n```bash\n# Test MCP server directly\necho '{\"jsonrpc\":\"2.0\",\"method\":\"tools/list\",\"id\":1}' | node index.js\n\n# Verify browser installation\nchromium-browser --version\n\n# Check Claude MCP integration\nclaude mcp list\n```\n\n---\n\n## 🤝 Contributing\n\nWe welcome contributions to democratize AI access for developers worldwide.\n\n### Areas for Contribution:\n- 📱 Mobile browser support (Android/iOS testing)\n- 🔧 Additional MCP tools and integrations \n- ⚡ Performance optimizations for smaller devices\n- 📚 Tutorial content and use-case examples\n\n### Development Setup:\n```bash\ngit clone https://github.com/nfodor/mcp-chromium-arm64\ncd mcp-chromium-arm64\nnpm install\n# Ready to use -
