In an interview with Macworld, Ken Bereskin, director of OS technologies in Apple’s worldwide product marketing group, said that Mac OS X’s sea-blue Aqua user interface would not be available in other colours. However, Bereskin understands that "users enjoy customization" and believes that OS X’s preferences allow for a "high degree" of personalization.

Bereskin also told Macworld that OS X will feature a new printer manager, replacing the antiquated Chooser, and that the screen Dock is likely to include "visual indicators" to display which applications are currently running. The fate of the Scrapbook and Stickies remains shrouded in secrecy.

Mac OS X should run on any G3 or G4 Power Mac, PowerBook, iMac or iBook boasting at least 64MB of RAM, Bereskin told Macworld.

The next-generation operating system – slated for release this summer – is going to bring joy to Macintosh users, according to Bereskin: "Speaking as someone who has stared at a Macintosh screen for 15 or 16 years, I am sure that people are going to love this way of working. They’ll just adore OS X’s new browser functionality".

Bereskin could not comment on Apple’s plans to sell multiprocessing Power Macs, but did say that Mac OS X was built from the ground up to support the high-performance mode of working. Apple hasn’t sold multiprocessing Macs for several years, and many users have been dreaming of Macs with multiple G3 or G4 chips.
