The most useful report is a run on a macOS build I have not tried. Open an issue with the macOS version and build (sw_vers), the Mac or Hackintosh, the tool and command line, and its full output. If a tool crashes or a number looks wrong (an instance size, a slot, a request table), say what you expected and where that came from. For dump.py, source.json from the dump is enough to identify the collection; please don't attach the carved .macho copies, they are Apple's binaries.
Pull requests: keep them small and say how you tested them. Support for another family's classes in dump.py or genhdr.py, Apple Silicon collections, or another LLVM's llvm-objdump output are all welcome. I read and test every PR before merging. AI-assisted PRs are fine as long as you can explain the change, which is the same bar I hold my own code to.
Contributions are under the ISC licence, except changes to the parts of genhdr.py adapted from ga403wm-hackintosh, which stay BSD-3-Clause-Clear (see NOTICE.md).
