The Mac port based on Emacs 24.3.90 pretest is now available from


This version (4.9X) should be regarded as experimental/hackers-only.

refrain from distributing this in any different form, including for
(binary) distribution basis, until the version gets to 5.0.

* emacs-24.3.90-mac-4.90 [experimental/hackers-only] (2014-04-14)
Based on Emacs 24.3.90.
High-resolution icons are now distributed as a separate package.
File notification is supported via GLib (you'll also need `pkg-config'
when running the configure command).
The `image-io' image type supports `:max-width', `:max-height', and
`:format' keywords just as in `imagemagick'.
Now that Image mode supports multi-frame image navigation (`f', 'b',
and `F'), you can browse multi-page documents in several formats that
`image-io' supports (e.g., PDF and DOC) with the setting like this:
  (when (and (image-type-available-p 'image-io)
             (not (boundp 'imagemagick-render-type)))
     ;; Image I/O is used as a fallback of ImageMagick.
     (setq imagemagick-enabled-types t)
     (setq imagemagick-types-inhibit
          (cons 'XML (delq 'PDF imagemagick-types-inhibit)))
Note: if you have ImageMagick installed, you need to build the Mac
port executable without the genuine ImageMagick support so `image-io'
can be used as a fallback of `imagemagick'.

** Improvements

*** Graphical drawing operations might be performed in non-main
threads via GCD (Grand Central Dispatch) on Mac OS X 10.6 and later.
You can turn this off by setting `mac-drawing-use-gcd' to nil.

*** DocView mode generates pixel-doubled "@2x" bitmap image files in
addition to normal ones on high-resolution environments such as Retina
display or HiDPI mode.
