"As some of you may know (and most of you probably don't), Apple is currently developing MacOS X, a replacement to MacOS based on top of Mach3 and BSD but with the traditional Macintosh look and feel. In order to allow developers to quickly port their existing MacOS-based applications to MacOS X, Apple has created a portability layer named Carbon. Carbon takes the nearly 9000 MacOS APIs, trims the dead weight, adds some new stuff, and offers the remaining 6000 APIs for use on top of MacOS X. All developers need to do is tweak their existing MacOS code to fit the new Carbon API and their apps will run in a separate process, taking full advantage of MacOS X's memory protection and pre-emptiveness."
"Around May, 1999 (Mozilla milestone 5, or M5) we made those modifcations to Mozilla and created a single binary that ran on both MacOS 8.5 and MacOS X. The resulting app, code named Fizzilla, made its public debut onstage at the MacOS X Session at Apple's WWDC '99. People liked it."
"In the time between May and December, 1999, Apple did a significant amount of profiling work on MacOS X using Fizzilla as a test application. Their findings set us in a new direction which we believe will yield the best possible solution for many of the problems which have traditonally plagued our MacOS products."
