Mac OS 9.x, based on Mac OS 8 was the final product based on the classic MacOS architecture. Like previous version, it lacks true protected memory or pre-emptive multitasking. MacOS 9 was abandoned in favor of of the Unix-ish NextStep/Openstep based Mac OS X.

Running MacOS 9 requires a supported Power PC based Macintosh (see the compatibility matrix), or the following emulator:
