Aquamacs is an Emacs text editor for macOS. It is based on GNU Emacs, currently tracking the GNU Emacs version 25.3 branch. Although GNU Emacs has had native UI support on macOS using the Cocoa API since version 23, Aquamacs modifies the user interface to conform with macOS standards in favor of Emacs standards.

Among the changes are that Aquamacs, by default, shows tabs to organize different file buffers in windows. A range of keybindings (keyboard shortcuts) that are standard on macOS, such as Command-W to close a window, or Command-S to save the file, are available. A standard printing dialog and functions to efficiently use the Option key on Mac keyboards as Emacs Meta key have been added. The styles of windows can be automatically changed to suit the major mode used in the buffer shown. Visually, Aquamacs has been adapted in its icons and fonts to look similar to other Mac applications.[4]

Aquamacs is a distribution that includes a number of extensions to GNU Emacs to provide an integrated development environment and to support, among many formalisms, LaTeX, Python, Java, Lisp and Objective C editing, as well as the Emacs Speaks Statistics system for R and S. These packages are installed without the need of further configuration by the end user.

Aquamacs is designed to be highly compatible with Emacs, so that extension packages for GNU Emacs can be installed. Users can configure Aquamacs with Emacs customization options. They can also choose to bring back GNU Emacs behaviors.[5]

The current version of Aquamacs includes a Wikipedia mode. This can be used to edit text for Wikipedia and any other wiki based on the MediaWiki software application.[6][7] The mediawiki package is available for GNU Emacs through the package system.

The editor is self-documenting and is supported by a community of users.[8]
