It would be followed in January 1998 by a consumer release codenamed Rhapsody Premier, containing a preliminary version of Blue Box, the compatibility environment that would allow Rhapsody to run Mac OS apps. Īpple initially planned to release a developer preview of Rhapsody in the third quarter of 1997. Rhapsody was announced by Gil Amelio at the JanuMacworld Expo SF, and first demonstrated at the May 1997 Worldwide Developers Conference (WWDC). Apple's executive team considered BeOS, NeXT's NeXTSTEP, Sun Microsystems' Solaris, and Windows NT, and eventually acquired NeXT in December 1996. In response, Apple CEO Gil Amelio decided to acquire or license an already-built operating system from another company. Apple's most promising next-generation operating system, Copland, was mismanaged and had to be abandoned in 1996. Apple made several attempts to develop modern replacements for Mac OS, which all failed, harming public confidence in the company, while Macintosh sales continued to decline. At the time, Mac OS was still a single-user OS, and had gained a reputation for being unstable. In 1993, Microsoft had introduced the next-generation Windows NT, which was a processor-independent, multiprocessing and multi-user operating system. In the mid-1990s, Mac OS was falling behind Windows.

Several existing classic Mac OS frameworks were ported, including QuickTime and AppleSearch. Eventually, the non-Apple platforms were discontinued, and later versions consist primarily of the OPENSTEP operating system ported to Power Macintosh, merging the Copland-originated GUI of Mac OS 8 with that of OPENSTEP. Its OPENSTEP based Yellow Box API frameworks were ported to Windows NT for creating cross-platform applications. Rhapsody represented a new and exploratory strategy for Apple, more than an operating system, and runs on x86-based PCs and on Power Macintosh. Targeting only developers for a transition period, its releases came between Apple's purchase of NeXT in late 1996 and the announcement of Mac OS X (later renamed macOS) in 1998. Rhapsody is the development series of Apple Computer's next-generation operating system.
