Mac OS 8 8.7 Beta

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.

Other Mac OS Versions:
| 1.x-6.x | 7.x | 8.x | 9.x | MacOS X | All |

Release notes

This is a Mac OS pre-release that includes some of the features found in MacOS 9.

Apple never released a final "8.7", instead the version number was bumped to 9.0.

To run this, we recommend the SheepShaver emulator.
