Had issues running Emacs on macOS Mojave (blank unresponsive screen). Bleeding edge emacs-plus did the job:

brew tap d12frosted/emacs-plus
brew install emacs-plus --without-spacemacs-icon --HEAD

brew info emacs-plus

==> Caveats
Emacs.app was installed to:
  /Users/some-user/homebrew/Cellar/emacs-plus/26.1

To link the application to default Homebrew App location:
  brew linkapps
or:
  ln -s /Users/some-user/homebrew/Cellar/emacs-plus/26.1/Emacs.app /Applications

--natural-title-bar option was removed from this formula, in order to
  duplicate its effect add following line to your init.el file
  (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t))
  (add-to-list 'default-frame-alist '(ns-appearance . dark))
or:
  (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t))
  (add-to-list 'default-frame-alist '(ns-appearance . light))

If you are using macOS Mojave, please note that most of the experimental
options are forbidden on Mojave. This is temporary decision.


To have launchd start d12frosted/emacs-plus/emacs-plus now and restart at login:
  brew services start d12frosted/emacs-plus/emacs-plus
Or, if you don't want/need a background service you can just run:
  emacs
