A command line tool for modifying Mach-O binaries on macOS and iOS. It can insert or remove load commands, strip or repair code signatures, and disable ASLR.
Use cases
- inject a dylib into an existing Mach-O binary
- remove code signature from an iOS app binary
- disable ASLR in a macOS executable
- remove load commands pointing to a dylib
- resign a binary after patching it
When to choose
- you need to patch Mach-O binaries for iOS tweak development or reverse engineering
- you want a lightweight scriptable alternative to install_name_tool for load command manipulation
When to avoid
- you need actively maintained tooling with recent macOS code-signing support
- you only want to inspect binaries rather than modify them
