Mac OS 8 8.6
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
8.6 was a minor release that mainly increased stability and increased battery life on laptops.
Apple offered a free update to 8.6 for users of 8.5 and 8.5.1.
Installation instructions
Emulation notes: To run MacOS 8.6 on newer hardware, we recommend the SheepShaver emulator, which emulates a PowerPC Macintosh.
