In the mid–1990s, Apple worked on an operating system called Copland, which was announced but never commercially released because of project management issues and feature creep.

In the mid-1990s, Apple was developing an operating system known as Copland, but never launched it commercially due to management problems and excessive features. Some Copland elements were later incorporated into Mac OS 7.6 and Mac OS 8, yet the OS was deemed too problematic overall, leading to its cancellation before completion.
Michael Steil, a specialist in reverse engineering vintage tech, managed to get Copland running in emulation lately. He adapted the open-source Power Mac emulator DingusPPC, requiring 11 changes for Copland to start up. Steil offers a browser-based version of Copland on his website, along with the adjustments needed for emulation.
During Copland's creation, Apple released three beta versions, with the final one being D11E4, which Steil managed to get working. He noted that Copland is notoriously difficult to run on actual hardware and wasn't previously accessible in emulation. Following Copland's cancellation in August 1996, Apple sought an alternative OS, culminating in the acquisition of NeXT in 1997 and Steve Jobs' return to Apple.
NeXTSTEP, NeXT's OS, served as the foundation for Mac OS X. The article "You Can Now Try Apple's Unreleased Copland OS in Your Browser" originally published on MacRumors.com, discusses this story.
