https://en.wikipedia.org/wiki/Rhapsody_(operating_system)Rhapsody was the code name given to Apple Computer's next-generation operating system during the period of its development between Apple's purchase of NeXT in late 1996 and the announcement of Mac OS X (now called "macOS") in 1998. At first more than an operating system,
Rhapsody represented a new strategy for Apple, who intended the operating system to run on x86-based PCs and DEC Alpha workstations[citation needed] as well as on PowerPC-based Macintosh hardware. In addition, the underlying API frameworks would be ported to run natively on Microsoft Windows NT. Eventually the non-Apple platforms were dropped and later versions consisted primarily of the OPENSTEP operating system ported to the Power Macintosh along with a new GUI to make it appear more Mac-like. Several existing "classic" Mac OS technologies were also ported to Rhapsody, including QuickTime and AppleSearch. Rhapsody could also run Mac OS 8 in a "Blue Box" emulation layer
