So far I have only used Emacs on Ubuntu. So it was time for a change, and on my new MacBook Pro, I installed Emacs 24.5 from http://emacsformacosx.com/

Now, when I go to the terminal window and type

$ /Applications/Emacs.app/Contents/MacOS/Emacs -mm

Emacs does not open maximized. What am I missing here? (I have not created any Emacs init file yet)

As far as I know, the -mm -fs -fh -fw flags do not work with OS X because they require X11 to work. I've tried them in Linux and they work fine there. However the -g flag does work. For a 1920x1200 display you can pass a geometry of 271x82 and you'll get a maximised frame.

I prefer to use code to set this up, I use the following snippet to maximise emacs when started, the benefit is that no matter the display geometry I always get emacs to display as expected.

(let ((px (display-pixel-width))
  (py (display-pixel-height))
  (fx (frame-char-width))
  (fy (frame-char-height))
  tx ty)
(setq tx (- (/ px fx) 7))
(setq ty (- (/ py fy) 4))
(setq initial-frame-alist '((top . 2) (left . 2)))
(add-to-list 'default-frame-alist (cons 'width tx))
(add-to-list 'default-frame-alist (cons 'height ty)))

I'm sure there are other ways to do this, maybe better ways, but this is enough for my needs.

Adding the following to my init file works:

(add-to-list 'default-frame-alist '(fullscreen . maximized))
