BTW: If I try to build LyX 2.4 with minimum os version 10.11 I get this:

/Users/lyx/git/lyx/src/insets/ExternalTransforms.cpp:334:20: error: 'any_cast<std::__1::function<std::__1::unique_ptr<const lyx::external::TransformOption, std::__1::default_delete<const
      lyx::external::TransformOption> > (std::__1::basic_string<char>)> >' is unavailable: introduced in macOS 10.14
        Factory factory = any_cast<Factory>(any_factory);
