The Free On-line Dictionary of Computing (30 December 2018):

Rhapsody

    Apple Computer, Inc.'s next-generation
   operating system for PowerPC processor-based systems
   capable of running Mac OS.  Rhapsody includes four
   components: the Core OS, the Blue Box (the implementation of
   the Mac OS within Rhapsody), the Yellow Box, and the Advanced
   Mac Look and Feel.

   "Rhapsody for Intel" runs on Intel processors [which ones?].
   It includes the Core OS, the Yellow Box, and the Advanced
   Mac Look and Feel, but lacks the Blue Box and therefore is
   unable to run Mac OS software.

   "Rhapsody Developer Release" is a developer-only release of
   Rhapsody, scheduled for release in late 1997.  It will go to
   all members of the Macintosh Developer Program and the Apple
   Media Program worldwide who have signed nondisclosure
   agreements.

   "Rhapsody Premier Release" will be the second release of
   Rhapsody, scheduled for early 1998.  It is meant for early
   adopters and will include a partially finished human interface
   and a partial implementation of the Blue Box.

   "Rhapsody Unified Release" will be the third release,
   scheduled for mid-1998.  It will be the first public release,
   and it will include the first full implementation of the
   Rhapsody human interface and the Blue Box.
