In 1984 Apple Computer unveiled their Macintosh. It included a new user interface that revolutionized the way people though about computer interaction. Originally referred to as simply 'Macintosh System', the underlying OS was a single-tasking disk system for the Motorola 68K CPU. Significant changes were made in MacOS 7.x.

Emulation note: For MacOS 0.x-6.x we recommend the vMac Mini emulator.

This article contains the Mac OS X Update 10.3.1 information and a link to the Mac OS X Update 10.3.1 software. The 10.3.1 Update delivers enhanced functionality and improved reliability for the following applications, services and technologies: FileVault, Printing, WebDav, and FireWire 800 drives.

It is possible to write Macintosh 400k/800k images to a real disk using a Kryoflux.
