This tool does not support macOS caches and most likely never will, unfortunately. The main goal for this project was to extract from arm64 iOS caches.

Found another tool that works with macOS caches: dyld-shared-cache-extractor
However it doesn't seem to extract as much information as DyldExtractor when running against the same iOS 12.5.5 cache.

Yep, that tool actually uses a tool in dyld's source code. It only pulls out debug symbols for XCode.
