mach-o

My implementation for the nm and otool commands. Developed for macOS binaries with support for x86-64, i386, arm and arm64 machines.

A lib to distinguish a shared library from an executable. Mostly for ELF, but some rudimentary (file name extension-based) support of windows was added.

In-memory loading and executing Mach-O executable.

Run Intel (x86_64) macOS applications on Apple Silicon after Rosetta is removed. Clean-room translator: Mach-O loader, isolated guest address space, x86-64 interpreter.

Cross-compile TH splices on iOS

A modern toolchain for booting custom kernels on pre-A7 iOS devices (iPhone 3GS, iPod touch 3, iPad 1). Modern-clang cross-compile pipeline for iOS 5 armv7 binaries, an offline kernelcache patcher, and a forgotten-PIN data recovery walkthrough.

A compiler small enough to read, written in itself.

Deterministic binary analysis, runtime instrumentation & protocol reverse-engineering skill for AI coding agents.

Find Intel-only apps that still rely on Rosetta on your Apple Silicon Mac, and check them for updates. SwiftUI.

🐞 A Swift library for parsing binary files to obtain DWARF information.

Native macOS workbench for inspecting code-signature entitlements, Mach-O evidence, embedded plists and strings, and build-scoped RunningBoard policy.

Decompiling Ultimate Mortal Kombat 3 (iOS, EA Mobile 2011) into readable C, targeting a native Windows/Linux port. The retail binary kept its STABS table: 4,342 named functions across 135 source files. Hand-written C ships only after differential testing against a static ARM-to-C recompiler.
