Or just build the SVN branch if you want to stay on the 'latest and greatest'. Its now v0.194, and builds with no trouble now that the OS requirement was changed. All you really need is the SDL2 and Qt 4.8.7 frameworks along with XCode, type 'make' and you're good to go. The wiki says after OS 10.10 you have to build Qt with home-brew, but I still have the frameworks installed on 10.13 and they work fine. You shouldn't have to edit anything, on my Qt installation, the g++-macx.conf file was already set to 10.6, and I didn't have to build without Phonon either.
