Long story short, Alfred 2 and Emacs installed via Homebrew don’t exactly play along nicely. Alfred 2 doesn’t like to follow symlinks so it won’t open Emacs.
I had just posted on GetSatisfaction then realized that the new (awesome!) workflows would allow me to fix this myself before they intervened.
Note, this workflow assumes that you’ve installed the latest Emacs from Homebrew with the cocoa flag (24.3 as of this writing):
brew install emacs --cocoa
If you’ve got Emacs but the wrong version, update it with:
brew update brew upgrade emacs --cocoa
Or simply edit my workflow and update it to use the latest path.
