Mac OS 9 is the final major release of Apple's Mac OS before the launch of OS X. Introduced on October 23, 1999, Apple positioned it as "The Best Internet Operating System Ever,"[1] highlighting Sherlock 2's Internet search capabilities, integration with Apple's free online services known as iTools and improved Open Transport networking.
While Mac OS 9 lacks protected memory and full pre-emptive multitasking,[2] lasting improvements include the introduction of an automated Software Update engine and support for multiple users.
Apple discontinued development of Mac OS 9 in 2002, transitioning all future development to Mac OS X. Since that time, no updates have been released. The final updates to Mac OS 9 addressed compatibility issues with OS X while running in the Classic Environment and compatibility with Carbon applications. At the 2002 World Wide Developers Conference, Steve Jobs began his keynote address by staging a mock funeral for OS 9.[3] However, there are still users of Mac OS 9 today. Specifically retro-gamers, people using old software that was discontinued before the introduction of OS X or users of old hardware incompatible with Mac OS X. (680X0 and PowerPC Macs made before the introduction of the G3 processor.)

Apple billed Mac OS 9 as including "50 New Features" and heavily marketed its Sherlock 2 software, which introduced a 'channels' feature for searching different online resources and introduced a QuickTime-like metallic appearance. Mac OS 9 also featured integrated support for Apple’s suite of Internet services known as iTools (later re-branded as .Mac, then MobileMe, which is now known as iCloud) and included improved TCP/IP functionality with Open Transport 2.5.
Other features new to Mac OS 9 include:[4]
PowerPC versions of Mac OS X prior to 10.5 include a compatibility layer called Classic, enabling users to run applications and hardware requiring Mac OS 9 from within Mac OS X. This is achieved through running Mac OS 9 without access to Finder inside Mac OS X. This requires Mac OS 9 to be installed on the computer, even if computers that can run the Classic environment are not necessarily able to boot into Mac OS 9. Most Mac OS 9 applications run well in Classic, although some applications demonstrate screen redraw problems. In addition, scanner drivers and many other utilities no longer work, and in the Classic environment there is no access to Finder or the control panel. For changing settings you must boot into Mac OS 9 and use the control panels from within the OS.
In May 2002, at Apple's Worldwide Developers Conference in San Jose, California, Steve Jobs, accompanied by a coffin, held a mock funeral[3] to announce that Apple had stopped development of Mac OS 9. Mac OS 9.2.2, introduced in December 2001, was the final version of Mac OS 9 and the end of the classic Mac OS.
In June 2005, Jobs announced that the Macintosh platform would be transitioning to Intel x86 microprocessors. Developer documentation of the Rosetta PowerPC emulation layer revealed that applications written for Mac OS 8 or 9 would not run on x86-based Macs. The Classic Environment remains in the PowerPC version of Mac OS X 10.4; however, x86 versions of OS X do not support the Classic environment.
As a workaround for Intel-based Macs, Mac OS 9 can be emulated up to version 9.0.4 by using SheepShaver, a PowerPC emulator. It cannot emulate above 9.0.4 because SheepShaver does not emulate a memory management unit. The PearPC PowerPC emulator does not support Mac OS 9.[6]

Updates to Mac OS 9 include 9.0.4, 9.1, 9.2.1, and 9.2.2. Mac OS 9.0.4 was a collection of bug fixes primarily relating to USB and FireWire support. OS 9.1 included integrated CD burning support in the Macintosh Finder and added a new Window menu in the Finder for switching between open windows. Mac OS 9.2 increased performance noticeably and improved Classic Environment support. While Mac OS 9.2 is only officially supported on G3 Power Macs, it could still be installed on certain unsupported PowerPC models through the use of third-party software, such as OS 9 Helper. [1]

Note 1: It may be noted that some G4 Macs can only run at least Mac OS 9.1, and some only run at least Mac OS 9.2. This is because G4 Mac development occurred during the classic Mac OS period.
Note 2: G5 Macs can only run at least Mac OS 9.2, and can only run its compatible versions of Mac OS 9 in Mac OS X's Classic Environment because with their development in the Mac OS X days, G5 Macs were designed to only have Darwin real-boot support.
Retail copies of Mac OS 9 are still available from several Internet businesses at varying prices. Mac OS 9 is no longer available from Apple. Although now classified as abandonware, as development on it has ended, it is still in use by those who cannot upgrade to Mac OS X due to hardware limitations, or prefer it to Mac OS X. Mac OS 9 is also a popular choice for retrocomputing hobbyists. Mac gamers also sometimes revert to Classic (often via emulation) in order to play some of the earlier, non-supported games, for example, Civilization II, and the Marathon Trilogy.
