A command line utility written in C that inserts a dylib load command (LC_LOAD_DYLIB or LC_LOAD_WEAK_DYLIB) into Mach-O binaries, including fat binaries. It also handles updating the mach header and optionally stripping code signatures.

Use cases

• inject a dylib into a Mach-O binary
• patch an executable to load an extra library
• remove code signature from a macOS binary
• add LC_LOAD_DYLIB load command to a fat binary
• make an app load a tweak dylib on macOS or iOS

When to choose

• you need to modify an existing Mach-O binary to load an additional dylib without recompiling
• you are doing reverse engineering or tweak development on macOS/iOS binaries
• you want a simple, scriptable CLI for binary patching

When to avoid

• you need to inject code into ELF or PE binaries (Linux/Windows formats)
• you want a GUI tool or a library API rather than a CLI
• you need to preserve valid code signatures, since patching typically requires stripping them
