It should be simple enough to implement, but the Emacs client ( /Applications/Emacs.app/Contents/MacOS/bin/emacsclient) seems to have problems locating the server from time to time. Instead, I decided to use the Emacs client to start the server, if it cannot detect a running Emacs. Notably: Core Text for text rendering, which improves text appearance and Unicode support. Note that GNU Emacs itself has native OS X support as well, but lacks the OS X specific additions, which this patch set provides. Open up System Preferences > Users & Groups > Login Items and now you can press the + button and choose Emacs Server. However, I never found this to be useful. Emacs Mac Port is a patch set for GNU Emacs proper for better OS X integration. To start the Emacs server, it is possible to ask macOS to launch the Emacs daemon automatically when the user logs in (see here). This was when I realized that I should investigate the client/server mode. Since the Mac OS code is now part of the standard Emacs distribution, it is. It is easily extensible since its editing commands are written in Lisp. Emacs also has an extensive interactive manual browser. Users new to Emacs will be able to use basic features fairly rapidly by studying the tutorial and using the self-documentation features. What I wanted was for the running Emacs to open a new buffer. Recently it has even been used to discuss matters concerning Emacs for Mac OS X. GNU Emacs is a self-documenting, customizable, extensible real-time display editor. The problem with the emacs shell command, though, was that if I use it to open a second document, a new instance of Emacs would be launched. However, I eventually decided to switch to the GUI mode because I liked how org-mode documents are rendered in GUI mode. I used to use emacsnw exclusively, because I thought that managing an addition macOS window was a hassle. Function emacs () alias emacsnw = '/Applications/Emacs.app/Contents/MacOS/Emacs -nw'
