WWDC'97 was the first show after the purchase of NeXT

The show focused primarily on the work in progress, including a short history of the development efforts since the two development teams had been merged on February 4. Several new additions to the system were also demonstrated, including tabbed and outline views, and a new object-based graphics layer (NSBezier).

1998

In response to developer comments about the new operating system, the "big announcement" at WWDC'98 was the introduction of Carbon

OPENSTEP was a specific implementation of the OpenStep API developed...

. Under the original Rhapsody plans, classic applications would run in sandboxed installation of the classic Mac OS, (called the Blue Box) and have no access to the new Mac OS X features. To receive new features, such as protected memory and preemptive multitasking, developers would have to rewrite their applications using the Yellow Box API. Developer complaints about the major porting effort to what was then a shrinking market and warnings that they might simply abandon the platform, led Apple to reconsider the original plan. Carbon addressed the problem by dramatically reducing the effort needed, while exposing some of the new functionality of the underlying OS. Another major introduction at WWDC'98 was the Quartz
Quartz 2D

 model from the classic OS, as well (as it was later learned) as Java2D. Supporting QuickDraw directly in the graphics model also led to a related announcement, that the Blue Box would now be "invisible", integrated into the existing desktop as opposed to an entirely separate window.

1999

WWDC'99 was essentially a "progress report" as the plans outlined in WWDC'98 came to fruition. Three major announcements were the "opening" of the operating system underlying the new OS as Darwin

 as the primary 3D API. The system formerly known as OpenStep, and referred to during development as "Yellow Box" was formally re-named "Cocoa". 2563 developers attended.

2000

Much the same as WWDC'99, 2000 was another "progress report" on the way to the upcoming release of Mac OS X

2002

Mac OS X v.10.2, QuickTime 6 and Rendezvous (now known as Bonjour) were presented. Apple also said farewell to Mac OS 9 with a mock funeral, and told the developers that there would be no more Mac OS 9 development, reinforcing that the future of the Mac was now entirely on Mac OS X.

New displays were introduced in 23 and 30-inch widescreen. iTunes 4.9, the first version with integrated podcast support, was demoed by Jobs. Mac OS X Tiger (10.4) was also previewed. All attendees received a developer preview of Tiger, a simple grey t-shirt with the Apple logo on the front and "WWDC2004" on the back, a backpack capable of holding a 17-inch PowerBook, and a copy of Apple Remote Desktop 2.0.
