Vim from Homebrew + YouCompleteMe works for me.

* brew install vim

* alias vim="/usr/local/Cellar/vim/7.3.632/bin/vim"

* :BundleInstall 'Valloric/YouCompleteMe'

* Make the ycm_build directory:

    cd ~
    mkdir ycm_build
    cd ycm_build

* brew install cmake

* Run cmake from the ycm_build dir:

    cmake -G "Unix Makefiles" . ~/.vim/bundle/YouCompleteMe/cpp

* make ycm_core

And boom, YouCompleteMe is running for me.

Works amazing. Always had a problem with having to press a button to autocomplete. The cognitive reflection of "okay, I want help completing this word" usually defeats the speed improvement for me.
