How can I make 'emacsclient' open in native fullscreen every time I launch it from the terminal in macOS?

Question

MacOS 14 Sonoma
emacs-plus / doomemacs

I use emacsclient -c to launch Emacs from the terminal. It opens in a small window with no focus. It is a waste to manually set fullscreen.

I want Emacs to open in fullscreen mode with input focus, handsfree. Also, I prefer native fullscreen because non-native fullscreen blocks other windows, which I dislike.

Include the following lines in your configuration file (~/.config/doom/config.el for doomemacs or ~/.emacs.d/init.el):

(setq ns-use-native-fullscreen :true)
(add-to-list 'default-frame-alist '(fullscreen . fullscreen))

Save (C-x C-s) the configuration and exit emacs. The next time you launch Emacs, it will open in native fullscreen mode with input focus.
