Mac OS 9

Sherlock 2 for Mac OS 9 with the new metallic appearance |
Mac OS 9 was the last version of what has since become known as the classic Macintosh Operating System (
Mac OS), introduced by
Apple Computer on
October 23,
1999. Upon introduction, Mac OS 9 was advertised as having "50 new features," including Sherlock 2, an improvement over the original Sherlock, which had resembled FindFile. Sherlock 2, among other things, boasted a new 'channels' feature and a QuickTime-like metallic appearance (which some people detested, prompting a third-party patch to be released, stripping it of its metallic interface). Apple also was quick to point out Mac OS 9's 128-bit encryption capabilities.
Codenamed Sonata, and originally intended to debut as
Mac OS 8.7, Mac OS 9 is by some considered the most functional version of the original Mac OS. Still, Mac OS 9 did not include features common to modern operating systems, such as
protected memory (which some people have incorrectly claimed was implemented in beta versions of Mac OS 9.1 and pulled at Apple CEO
Steve Jobs' command [
1]) and
pre-emptive multitasking (except through the nanokernel that was added in Mac OS 8.6). Mac OS 9's lasting improvements include the addition of an automated
Software Update engine, and support for multiple users. Mac OS 9 retained the
Platinum theme of Mac OS 8, though it was open to different themes created by third parties, no hacks required.
Apple billed Mac OS 9 as "best Internet operating system ever," and heavily marketed its
Sherlock 2 software, which extended Apple's search tool to many online resources. In addition, Mac OS 9 featured integrated support for Apple's suite of Internet tools then known as iTools (now
.Mac), and included improved
Open Transport networking.
In May 2002, at Apple's
Worldwide Developers Conference in
San Jose,
California, Jobs delivered a mock
funeral for Mac OS 9 during his keynote address, dressed in black and accompanied by a
coffin. The purpose of the theatrics was 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 indeed, the end of the classic Mac OS.
PowerPC versions of
Mac OS X include a compatibility layer called
Classic that runs a complete Mac OS 9 installation within OS X for applications and hardware that require Mac OS 9. Most Mac OS 9 applications did run well in Classic, although some applications had screen redraw problems, and scanner drivers and many other utilities no longer worked.
In June 2005, Jobs announced that the Macintosh platform would be transitioning to
Intel x86 microprocessors. One consequence of this change was revealed in the developer documentation for the
Rosetta PowerPC emulation layer, which is designed to allow PowerPC Macintosh applications to run on the Intel processor. The documentation explicitly states that applications written for Mac OS 8 or 9 will not run on x86-based Macs. It is possible that a third-party software developer may create a workaround for this, but so far none have been announced.
Compared to
Mac OS 8, Mac OS 9 offered:
*
Network Browser, a new application for browsing networks and connecting to other computers on a network. These tasks were previously handled through the
Chooser application.
* Support for files larger than 2
GB* Several improvements to the Appearance control panel.
*
Sherlock 2, an updated searching utility for searching Internet and hard disk content.
*
PlainTalk 2 improved speech synthesis and recognition.
* Added File
Encryption into the Finder.
* Added Unix volume support.
* Remote Access Personal Server 3.5, included in the package, supports
TCP/IP clients over
PPP.
* CD Burning in the
Finder, in a later update.
* A completely new Sound control panel.
* iTools Internet tools (later renamed
.Mac).
* Support for multiple user accounts, without using
At Ease.
*
Keychain Access added, a new feature allowing users to save passwords in protected keychains.
* New version of
AppleScript* New "Software Update" system allowing for system software updates through a control panel which automatically downloads and installs new updates safely.
*
USB Printer Sharing, a control panel that allowed certain models of USB printers to be shared across a TCP/IP network.

Updates to Mac OS 9 include 9.0.4, 9.1, and 9.2.1. 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 within the
Finder, and a new Finder menu, Window, which allowed users to switch between open windows. Mac OS 9.2 introduced minimum system requirements of a G3 processor, which brought about noticeable speed improvements both within Mac OS 9 and through the Classic environment of Mac OS X.
Due to the perceived naming similarity with
Microware's
OS-9, Microware sued Apple for trademark infringement. Later, a judge rejected the claim, saying there was little chance of confusion.
For some time after the discontinuation of Mac OS 9, Apple sold retail copies of Mac OS 9 for $19.95 to qualified OS X purchasers through the Mac OS 9.2 Fulfillment Program. This was designed to assist those who needed to run Classic applications yet did not own a copy of Mac OS 9. This program has since been abandoned.
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 an
MMU. The
PearPC emulator does not boot into Mac OS 9.
["FAQ." PearPC - PowerPC Architecture Emulator. Accessed on November 24, 2005.]Also, the famous
Happy Mac that served Mac users for almost 15 years has been changed to a full-color (32-bit) Happy Mac.
Retail copies of Mac OS 9 are still available from several Internet businesses at varying prices. Mac OS 9 is no longer included with any new retail Macintosh computers sold by Apple, and new machines from Apple will not run Mac OS 9 even in the Classic environment. Mac OS 9 is not yet classified as
abandonware, as it is still in wide use by those who cannot upgrade to Mac OS X due to hardware limitations, or prefer it to Mac OS X.
One small
easter egg, when in the "About This Computer" window, which shows the amount of memory being used, command-clicking on the Mac OS 9 picture sends you to Apple's page about their operating system www.apple.com/macos, which, since the introduction of Mac OS X, has been redirected to www.apple.com/macosx.
There was another easter egg in earlier versions of Mac OS 9, where if the user held ctrl + option + cmd, and selected the Apple menu, an "About The Mac OS 9 Team" menu would replace the "About This Computer". This was also present in OS 8.5, but was removed in later versions of Mac OS 9, from both the resource template and the data fork of the System file.
