At the 1998 [[Worldwide Developers Conference]] (WWDC), Apple announced a move that was intended as a response to complaints from Macintosh software developers who were not happy with the two options (Yellow Box and Blue Box) available in Rhapsody. Mac OS X would add another developer [[API]] to the existing ones in Rhapsody. Key APIs from the [[Macintosh Toolbox]] would be implemented in Mac OS X to run directly on the BSD layers of the operating system instead of in the emulated Macintosh layer. This modified interface, called [[Carbon (API)|Carbon]], would eliminate approximately 2000 troublesome API calls (of about 8000 total) and replace them with calls compatible with a modern OS.<ref name="anguish99summary">{{cite web | url=http://www.stepwise.com/SpecialCoverage/WWDC98/Summary.html | title=WWDC 98 Summary | author=Scott Anguish | date=May 1998 | publisher=stepwise.com | access-date=2006-10-13}} {{Dead link|date=October 2010|bot=H3llBot|fix-attempted=yes}}</ref>

At the 1999 WWDC, Apple revealed [[Quartz (graphics layer)|Quartz]], a new [[Portable Document Format]] (PDF) based windowing system for the operating system that was not encumbered with licensing fees to [[Adobe Systems|Adobe]] like the Display PostScript windowing system of NeXTSTEP. Apple also announced that the Yellow Box layer had been renamed [[Cocoa (API)|Cocoa]] and began to move away from their commitment to providing the Yellow Box on Windows. At this WWDC, Apple also showed Mac OS X booting off of a [[HFS Plus]] formatted drive for the first time.
