MacOS/System 0.97

System 0.97 was the first official version of the Apple Macintosh operating system. It came up along with the Macintosh 128k. It is available as a pre-installed copy on a 400k floppy disk image. Being based on the updated kernel of 0.85, this version is still quite buggy. However, most of the bugs from version 0.85 were already fixed.
