What Does Mac OS (Classic) Mean?
The classic Mac OS is Apple’s operating system (OS) used in Macintosh (Mac) computers prior to the release of the Mac OS X. Mac OS X is Apple’s current OS series.
In 1984, Apple released the original Mac OS. Known as Mac System Software, it came on a single floppy disk and included a graphical user interface (GUI) that focused on single users and tasks. Thus, multitasking was not required or used until subsequent Mac OS versions were released.
In fall 1999, the most recent classic Apple OS was released as Mac OS 9. A major release, Mac OS 9 was packed with new software tools and features and paved the way for Mac OS X.
