Mac OS 8 8.5/8.6/8.7
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.
Installation instructions
Mac OS 8.5 and later require a PowerPC based Macintosh. This version drops support for all m68k CPU based Macintosh computers.
Emulation notes: To run MacOS 8.5 on newer hardware, we recommend the SheepShaver emulator, which emulates a PowerPC Macintosh.
