Installing zenburn theme on Aquamacs

I followed the steps in https://github.com/bbatsov/zenburn-emacs to install zenburn theme using MELPA. But I had difficulty making it stick the next time it loads. These are the steps that works with me:

  1. Run Aquamacs
  2. Type: M-x package-install zenburn-theme
  3. I also added (load-theme ‘zenburn t) to “~/Library/Preferences/Aquamacs Emacs/Preferences.el”

But when I close and run Aquamacs again it is not exactly zenburn as the lower bar text are too dark. So I need to load the theme manually:

M-x load-theme zenburn

To make it stick, I follow the steps in: https://www.emacswiki.org/emacs/AquamacsFAQ#toc21

  1. With zenburn theme loaded, I go to: Menu -> Options → Appearance → Auto Faces → Use Current Face as Default
  2. And I do the next step: Menu → Options → Appearance → Adopt Face and Frame Parameters as Default
  3. Answer “Yes” to the dialog.
  4. Exit Aquamacs and “Y” to save the settings.
