Michael Steil has run Apple’s unfinished Copland operating system in emulation and published a browser version for testing.
He modified the open-source Power Mac emulator DingusPPC. Steil said booting Copland required 11 patches, which he also shared.
The last beta now runs
Steil got version D11E4 working, the third and final Copland beta. He said the system is notoriously difficult to run on real hardware and had not previously been available in emulation.
Apple developed Copland in the mid-1990s and announced the system, but never released it commercially. The project was abandoned because of management problems and feature creep.
After Apple canceled Copland in August 1996, it looked outside the company for a replacement operating system. Apple bought NeXT in 1997, and NeXTSTEP later became the precursor to Mac OS X. Parts of Copland had already been incorporated into Mac OS 7.6 and Mac OS 8.
