===Rhapsody===
With the purchase of [[NeXT]] in late 1996, Apple developed a new operating system strategy based largely on the existing [[OpenStep#OPENSTEP for Mach|OPENSTEP for Mach]] platform. The new [[Rhapsody (operating system)|Rhapsody]] OS strategy was relatively simple; it retained most of OpenStep's existing object libraries under the name "Yellow Box", ported the existing [[GUI]] in OPENSTEP for Mach and made it look more Mac-like, ported several major [[API]]s 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.

When this plan was revealed at the [[Worldwide Developers Conference]] (WWDC) in 1997 there was some push-back from existing Mac OS developers who were upset that their code bases would be effectively locked into an emulator that was unlikely to ever be updated. They took to calling the Blue Box the "penalty box".{{citation needed|date=March 2014}} Larger developers like [[Microsoft]] and [[Adobe Systems|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.

Apple took these concerns to heart. When [[Steve Jobs]] announced Apple's change in direction at the next WWDC in 1998, he stated that "what developers really wanted was a modern version of the Mac OS, and Apple [was] going to deliver it".

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]]. This was the only release based on the original Rhapsody concept.
