HISTORY -Up to Emacs 22, the OS X interface was implemented using the C-based -Carbon API. Starting with Emacs 23, the interface was rewritten in -Objective-C using the Cocoa API. Meanwhile, the Carbon interface has -been maintained independently under the name "mac". + +The Nextstep (NS) interface of GNU Emacs was originally written in +1994 for NeXTSTEP systems running Emacs 19 and subsequently ported to +OpenStep and then Rhapsody, which became Mac OS X. In 2004 it was +adapted to GNUstep, a free OpenStep implementation, and in 2008 it was +merged to the GNU Emacs trunk and released with Emacs 23. Around the +same time a separate Mac-only port using the Carbon APIs and +descending from a 2001 MacOS 8/9 port of Emacs 21 was removed. (It +remains available externally under the name "mac".)
