I have seen these screenshots and descriptions before.
When I was a registered Apple developer, I would receive CDs and documents in the mail, and by email. I have seen this document, in full, before. Tracking it down among my stuff would likely be an impossible task.
There were multiple versions of this document, over time and as Rhapsody evolved. I think they are mostly mock-ups and not screenshots of an actual running system.
It seems that at the very start, which these screenshots look like they’re from, the Copland and Rhapsody teams were trying to make Rhapsody look and feel mostly like Copland out of the NextStep.
However, I think Steve knew that in order to sell this new operating system, a completely new GUI theme would be necessary. I did like Aqua and all, but I wonder if Apple would have been able to sell their system as more of a powerful workstation had they continued on this refined “Copland” style instead.
Anyways, thanks for the post
@bottleworks and I hope you locate the full PDF file.
