We didn't release any mac bundle, because we have nobody with a mac in
our team, so in case you have mac and you have some programming
skills, you can figure out how to build huggle (need Qt and CMake) and
once you do that, let us know how you did it, so that we can update
the manual.

If you are willing to contribute more permanently, you can become
release manager for Mac builds and provide them for download every new
release. Let us know in e-mail or irc://chat.freenode.net/#huggle
