Introduction

What is ipsw 🤔

ipsw is a comprehensive command-line research framework for iOS and macOS that serves as your Swiss Army knife for Apple platform analysis. Whether you're a security researcher, reverse engineer, jailbreak developer, or iOS enthusiast, ipsw provides the tools you need to download, parse, analyze, and interact with Apple firmware and devices.

Core Capabilities

• 📱 IPSW/OTA Analysis - Download, extract, and analyze iOS firmware files from multiple sources
• 🔍 Binary Analysis - Advanced Mach-O parsing with ARM disassembly and AI-powered decompilation
• 🧠 dyld_shared_cache - Complete shared cache analysis with ObjC/Swift class dumping
• 🔧 Kernel Analysis - Kernelcache parsing, KEXT extraction, and symbolication
• 📲 Device Interaction - Comprehensive iOS device management and debugging via idev
• 🔐 Firmware Research - IMG4, iBoot, SEP, and co-processor firmware analysis
• 🏪 App Store Connect - Full API integration for app and certificate management
• 🛠️ Developer Tools - SSH, Frida integration, debugging, and reverse engineering utilities
• 🤖 AI-Powered Analysis - Integrated decompiler with support for Claude, OpenAI, Gemini, and Ollama
