Mac OS 8 Copland

Apple Mac OS 8 was another major overhaul of the OS from the earlier Mac OS 7. It added a new Platinum visual theme, a multi threaded Finder, better virtual memory, and many customization options. 8.5 and later require a PPC CPU. It was followed up by Mac OS 9.

Running MacOS 8 requires a supported Motorola 68K or Power PC based Macintosh (see the compatibility matrix), or one of the following emulators:

Basilisk II - Runs MacOS 7.x-8.1, emulates later color Motorola 68k based Macs.

SheepShaver - Runs MacOS 7.5.2-9.0.4, emulates a Power PC based Macintosh.

Copeland was an overambitious attempt to re-write the entire MacOS for PPC. Instead of reaching a single completed release, the features of Copeland were slowly merged in to the existing MacOS product.

Installation instructions

Installation notes: There are no known emulators that will run MacOS 8 Copeland. To run it, you must install it on a supported Macintosh PowerPC computer.
