Copland OS D11E4

Copland was a project at Apple Computer to create an updated version of the Macintosh operating system. It was to have introduced protected memory, multitasking and a number of new underlying operating system features, yet still be compatible with the vast majority of existing Mac software. Development began in 1994 and was underway in earnest by 1995. Starting around that time the system was also commonly referred to as System 8 or Mac OS 8. It uses the Mach Kernel of OS X.

During development the system started collecting new features at an alarming rate and the completion date continued to slip into the future. In 1996 Apple's newest CEO, Gil Amelio, hired Ellen Hancock away from National Semiconductor and put her in charge of engineering in an effort to try to get development back on track. Instead, she decided it was best to cancel the project outright and try to find a suitable 3rd party system to replace it. Development officially ended in August 1996, and after a short search they announced that Apple was buying NeXT in order to use their NeXTSTEP operating system as the basis of a new Mac OS.

Hancock also suggested that Apple should work on improving the existing Mac OS 7 while the new system matured. This process would eventually lead to the release of an unrelated operating system, re-using the name Mac OS 8. The new operating system based on NeXTSTEP shipped in 2001 as Mac OS X.
