antons/dyld-shared-cache-big-sur

Modifications to Apple's dyld project to fix Objective-C information when extracting dyld_shared_cache from macOS Big Sur to help Hopper generate readable pseudocode.

Note: macOS Big Sur beta 9 changed the format of dyld_shared_cache. Currently this project only supports beta 1-8.

Usage

1. Build dyld_shared_cache_util sheme, which will also build its dependency dsc_extractor. dyld_shared_cache_util is modified to look for dsc_extractor in the same directory.
2. ./dyld_shared_cache_util -extract ~/Developer/macOS\ Big\ Sur /System/Library/dyld/dyld_shared_cache_x86_64.
3. Decompile the extracted libraries with Hopper.
