MachIDE: Building a Native macOS IDE for Mach-O Decompilation from Scratch

Introducing MachIDE: Native macOS IDE for Binary Analysis

As developers and reverse engineers, having a robust, fast, and reliable IDE for analyzing Mach-O binaries is a game-changer. Today, I'm excited to share MachIDE – a fully native macOS IDE for disassembly, decompilation, patching, and dynamic instrumentation, with all data stored locally and zero external APIs.

Why MachIDE?

Existing reverse engineering tools often rely on external services or lack tight integration with macOS. MachIDE is designed to:

  • Analyze Mach-O binaries natively on macOS (arm64 & x86_64)
  • Decompile to human-readable pseudocode with cross-links to disassembly
  • Visualize control flow graphs (CFGs) for functions
  • Patch binaries safely with atomic undo/redo
  • Support dynamic analysis and instrumentation in sandboxed processes
  • Run plugins securely, isolated from the main app
  • Store all user data locally (projects, snapshots, cache) in SQLite

Core Features

Native Swift + Rust Architecture

  • SwiftUI + AppKit for the frontend
  • Rust backend for safe, high-performance memory management and analysis
  • IPC via UNIX domain sockets, all local and sandboxed

Extensible Plugin Ecosystem

  • Isolated process per plugin
  • Explicit capability granting
  • Event-driven IPC
  • Safe CPU/memory limits and execution timeouts

Comprehensive Analysis Workflow

  • Binary parsing & section analysis
  • Disassembly + Low-level IR generation
  • SSA transform, type inference, and CFG reconstruction
  • Pretty-printed pseudocode output with confidence scores
  • Undo/redo snapshots for every analysis and patch

Interactive UI & UX

  • Hex editor with inline editing
  • Disassembly and decompiler views with cross-links
  • CFG and call graph visualizations
  • Project outline, console, inspector, toolbar, and status bar
  • Smooth animations, tooltips, split views, and keyboard shortcuts

Security & Reliability

  • Sandboxed plugin processes
  • Optional AES-256 encryption per project
  • Checksum verification for all binaries and patches
  • Full offline operation – no network dependency
