Unfortunately, the person who has been providing binaries for macOS is no longer able to do so. Unless someone else steps up to fill the void, I have no WeiDU for our macOS users. The build instructions for macOS should still be applicable, with the caveat that WeiDU cannot be built with OCaml distributions that force immutable strings (so-called "safe strings"). I don't know if this is a version thing (likely) or an option when building OCaml, but versions around 4.07 and 4.08 have worked for me.
