Emacs Mac Port
What is this?
Official repository: https://bitbucket.org/mituharu/emacs-mac/overview
This is "Mac port" addition to GNU Emacs 25. This provides a native GUI support for Mac OS X 10.6 - 10.12. Note that Emacs 23 and later already contain the official GUI support via the NS (Cocoa) port for Mac OS X 10.4 and later. So if it is good enough for you, then you don't need to try this.
If you find a bug, then please try to reproduce it with some official builds such as X11 or NS (Cocoa). If it turns out to be specific to the Mac port, then please report it to email@example.com. Otherwise (i.e., it is also reproducible with official ones), report it using M-x report-emacs-bug USING THE OFFICIAL BUILD as such.
This build has many features, a great number of which are particularly helpful for Mac users. You can see the full list here.
