MachOView

MachOView is a graphical browser for Mach‑O files that runs on macOS. It lets developers open Intel and ARM binaries, inspect their internal structures, and modify them directly within the interface. The tool presents the file’s sections, symbols, and headers in a visual layout, and also includes a hex editor for low‑level inspection and in‑place editing.

The application targets developers who need to analyze or patch compiled macOS and iOS executables. Its Cocoa‑based user interface is built with C++ and Objective‑C 2.0, providing a native experience for macOS users. The MIT‑licensed project is marked as stable and has been maintained since its initial release in 2010.

Key capabilities include full navigation of Mach‑O components, support for both Intel and ARM architectures, and the ability to edit binary data without leaving the viewer. The software is distributed via SourceForge and is intended for use in reverse‑engineering, debugging, and binary‑level development tasks.
