There are several failing tests on macOS currently in the CI. These should be trivial test code issues, because the software as a whole does work on macOS. Investigate and fix.
Documentation is missing, so that will need to be written. Installation using macports and possibly nixpkgs (brew does not have cyrus-sasl, so it cannot be used alone) should be covered in the new documentation.
