DyldExtractor
A command-line tool to extract dylib files from the dyld shared cache file.
Starting with macOS 11, standalone binaries of system libraries are not shipped with the system anymore. That means we cannot reverse-engineer those system libraries / frameworks directly. Fortunately, dyld provided a utility bundle for extracting image files from the cache file. This tool is just a wrapper of that utility bundle.
Build
Clone the repo and build it with make:
git clone https://github.com/unixzii/DyldExtractor.git
cd DyldExtractor && make
Usage
OVERVIEW: dyld shared cache extractor
USAGE: ./dyld_extractor <cache file> [-v] [-d arg] [-l arg]
OPTIONS:
-v print verbose messages
-d set destination path for the extracted files
-l set path to dsc_extractor library
Notes for iOS
To extract iOS's dyld shared cache files, you may need to specify a different dsc_extractor library with -l option. The library can usually be found at /path/to/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/usr/lib/dsc_extractor.bundle.
