Mac OS 9 ended the era of "classic" Mac OS, passing features along to Mac OS X (X being the Roman numeral for 10), and the modern macOS. Mac OS 9 improved wireless networking support and introduced Remote Networking, on-the-fly file encryption, and an early version of multi-user support. It did add HFS+ and the ability to clone files in the background. Mac OS 8 wasn't very different from 7-it was named 8 to terminate third-party manufacturers' licenses to System 7 and stop the manufacturing of Mac clones. This update was called Mac OS 7.6, and the "Mac OS" naming trend would continue into Mac OS 8 and Mac OS 9 in 19. The naming system of Mac OS changed with an update to System 7. It also added new applications and changed the user interface quite a bit. It had virtual memory support, built-in cooperative multitasking, and added aliases. In late 1987, System Software 5 finally allowed Mac users to run more than one application at a time, which System Software 6 improved upon in 1988.īig changes came when System 7 arrived in 1991.
