Dyld Extractor

Dyld Extractor provides a precise, non-executable analysis of Mach-O binaries to reveal which dynamic libraries are linked and how the loader resolves them at runtime. The tool focuses on the dyld mechanism, extracting load commands such as LC_LOAD_DYLIB and LC_DYLIB, and listing both direct and transitive dependencies where available.

Conceptually, it builds a dependency graph by parsing headers, normalizing paths, and recording version information from LC_BUILD_VERSION or LC_DYLIB_VERSION. It supports universal (fat) binaries and per-arch results, presenting a unified view or architecture-specific reports.

Who benefits: developers validating release binaries, security analysts auditing third-party components, and build teams seeking reproducible dependency trees. Unique value derives from its focus on loader dynamics, explicit reporting of missing libraries, and per-arch resolution without executing code.

Core features include direct dependency extraction, optional transitive analysis, path normalization, and structured outputs intended for downstream tooling (JSON/CSV). Use cases include pre-release checks, CI gating, and risk assessment.
