Mac OS 8 is an operating system developed by Apple, which was released on 26 July 1997 for the 68k and PowerPC Macintosh platform. This version overhauls the user interface by introducing the Platinum theme. Mac OS 8.5 removed support for the 68k architecture due to Apple's intent to support PowerPC Macs.
