Those looking for a great alternative try using MPV.
$ brew install mpv
$ mpv ~/Media/my-movie.mp4
$ brew install mpv
$ mpv ~/Media/my-movie.mp4
MPV is indeed a good alternative, though.
I am currently on Windows and use MPV, I don't see why it should be exclusive in any way.
The dotfiles are compatible, and same goes for lua scripts. So there's no trade off at all that I've found. And it's nice to be able to just clone my dotfiles and have it work in OS X, and same for Windows.
EDIT: Yeah, I was just pointing out the fact that, if you're using MPC-HC, then you're probably using Windows. In which case, whilst MPV is a good alternative, you wouldn't be installing it with (Home)brew, which is a package manager for macOS.
