This is a fork from @limneos's great classdump-dyld.
I need a classdump to check some frameworks on a MacBook Pro M1 2020. Big Sur put frameworks into dyld_shared_cache. So far it seems classdump-dyld is the most convenient tool.
Since I only need it on macOS, I got rid of theos related stuff and made it compile with old make on macOS.
The original license is GPLv3.
I only tested it on Big Sur x86_64 and m1.
