Carbon consists of many libraries and functions that offer a Mac-like API, but running on top of the underlying Unix-like OS, rather than a copy of the Mac OS running in emulation.

In order to offer a real and well supported upgrade path for existing Mac OS code bases, Apple introduced the Carbon system. This was the only release based on the original Rhapsody concept.

The original Rhapsody concept, with only the Blue Box for running existing Mac OS software, was eventually released in 1999 as Mac OS X Server 1.0. The statement was met with thunderous applause. When Steve Jobs announced this change in direction at the 1998 WWDC, he stated that 'what developers really wanted was a modern version of the Mac OS, and Apple going to deliver it'. Larger developers like Microsoft and Adobe balked outright, and refused to consider porting to OpenStep, which was so different from the existing Mac OS that there was little or no compatibility.Īpple took these concerns to heart. They took to calling the Blue Box the 'penalty box'. When this plan was revealed at the Worldwide Developers Conference in 1997 there was some push-back from existing Mac OS developers, who were upset that their code bases would effectively be locked into an emulator that was unlikely to ever be updated. The new Rhapsody was relatively simple it retained most of OpenStep's existing object libraries under the name 'Yellow Box', ported OpenStep's existing GUI and made it look more Mac-like, ported several major APIs from the Mac OS to Rhapsody's underlying Unix-like system (notably QuickTime and AppleSearch), and added an emulator known as the 'Blue Box' that ran existing Mac OS software. With the purchase of NeXT in late 1996, Apple developed a new operating system strategy based largely on the existing OpenStep platform.

By the mid-1990s, most Mac software was written in C++ using CodeWarrior. Over time, a number of object libraries evolved on the Mac, notably the Object Pascal library MacApp and the Think Class Library (TCL) in Pascal, and later versions of MacApp and CodeWarrior's PowerPlant in C++. Much of the Macintosh Toolbox consisted of procedure calls, passing information back and forth between the API and program using a variety of data structures based on Pascal's variant record concept. The original Mac OS used Pascal as its primary development platform, and the APIs were heavily based on Pascal's call semantics. 'Carbonized' application Adobe Systems ImageReady v.7.0 running directly on Mac OS X version 10.2 Classic Mac OS programming Apple did not create a 64-bit version of Carbon while updating their other frameworks in the 2007 time-frame, and eventually deprecated the entire API in OS X 10.8 Mountain Lion, which was released on July 24, 2012. As the market has increasingly moved to the Cocoa-based frameworks, especially after the release of iOS, the need for a porting library was diluted. With the release of macOS 10.15 Catalina, the Carbon API was officially discontinued and removed, leaving Cocoa as the sole primary API for developing macOS applications.Ĭarbon was an important part of Apple's strategy for bringing Mac OS X to market, offering a path for quick porting of existing software applications, as well as a means of shipping applications that would run on either Mac OS X or the classic Mac OS.

Developers could use the Carbon APIs to port (“carbonize”) their “classic” Mac applications and software to the Mac OS X platform with little effort, compared to porting the app to the entirely different Cocoa system, which originated in OPENSTEP. Carbon provided a good degree of backward compatibility for programs that ran on Mac OS 8 and 9. at the Wayback Machine (archived April 20, 2009)Ĭarbon was one of two primary C-based application programming interfaces (APIs) developed by Apple for the macOS (formerly Mac OS X and OS X) operating system.
