October 23, 1999: Mac OS 9 Released
OS 9 was the last iteration of Apple's Classic Mac OS and it had users excited.
What was so great about OS 9? Things that Mac users take for granted today made their first appearance in OS 9. The list includes: automatic software updates, multiple accounts, and password key chaining.
Steve Jobs pitched OS 9 as the best "internet OS ever" but users of Mac clones were left out, OS 9 was a "Made by Apple" affair. OS 9 was released on October 23, 1999.
