The final developer build offers a glimpse of the future Cupertino abandoned for NeXT.
Key facts
- Rhapsody evolved into Mac OS X Server 1.0 in 1999 and the consumer release of Mac OS X 10.0 in 2001
- Mac OS 8.1 followed in 1998 with HFS+, Apple's new format for larger disks
- Apple CEO Gil Amelio had demonstrated Copland at the company's 1995 Worldwide Developers Conference, but the project never approached the stability required for release
- Mac OS 8, released in 1997, gained Copland's Platinum interface and a PowerPC-native, multithreaded Finder
Summary
Thirty years after Apple abandoned Copland, its doomed attempt to create a modern Mac operating system, a new emulator lets you try the final developer build in your browser. Copland was intended to replace Apple's System 7 with a PowerPC-native operating system built around a microkernel, protected memory, and preemptive multitasking for system services. Three unfinished developer builds, D7E1, D9, and D11E4, are publicly known. Now you can boot Apple Copland D11E4 in your browser and explore the unstable prerelease OS without installing anything.
