Mac OS X 10.6 Snow Leopard was billed as primarily under-the-hoodchanges to OS X 10.5 Leopard, butit was much more significant than that.

Snow Leopard was announced at the June 2008 Worldwide DeveloperConference (WWDC) and released on August 28, 2009.

For the first time since Mac OS 8.5 had been released in October1998, Apple left behind an entire processor architecure. Back then, itleft behind the Motorola 680x0 CPUs in favor of PowerPC (the first PPCMacs had been introduced in March 1994). With 10.6, Apple left behindPowerPC CPUs in favor of Intel (the first Intel Macs were introduced inJanuary 2006).

Big Changes with 10.6

Snow Leopard is smaller than Leopard. By removing PowerPC and otherunnecessary legacy code, Apple greatly reduced the drive space neededby the operating system. It takes up about half as much space and thuswill install about twice as fast as Leopard. That said, it makes moredemands of your hardware, so a Mac that runs Leopard comfortably with 1GB of memory may feel very sluggish with Snow Leopard once you havemore than a couple apps running. We strongly recommend at least 2 GB ofmemory for 10.6.
Grand CentralDispatch (GCD) means that the entire operating system is designedto take advantage of multiple cores, whether on one chip or more thanone. Process threads, which were handled by apps in the past, are nowhandled by the OS with new programs designed to use GCD. GCD willassign only as many threads to an app as it currently needs, whichmakes for better use of resources.
Full 64-bitsupport means programs will no longer be limited to 4 GB of RAM;the new maximum (16 exabytes) is meaningless, as no computer in theforseeable future will be able to hold billions of gigabytes of memory.Both the OS and almost all 'system applications' (Finder, Safari, Mail,iChat, iCal, etc.) are ready for 64-bit operation. And Snow Leopard iscompletely backwards-compatible with 32-bit apps. First generationIntel Macs designed around Intel Core Solo and Core Duo chips do notsupport 64-bit operation; all Macs since then do.
OpenCL takesadvantage of powerful modern graphic processing units (GPUs, a.k.a.'video cards') for more than displaying video. All of that processingpower will also be available for general purpose computing.
QuickTime Xintroduced a new QuickTime player and will take full advantage of CoreAudio, Core Video, and Core Animation. It can record audio and videousing your Mac's built-in microphone and webcam, and it can trim andexport for iPod, iPhone, Apple TV, YouTube, and MobileMe so you don'tneed to worry about which codec to use. QuickTime X supports HTTP livestreaming, which can adjust quality on the fly based on availablenetwork bandwidth. Of course it takes advantage of GCD and 64-bitoperation.
ExchangeSupport is built right into the OS. Mail, iCal, and Address Bookwill work with Microsoft Exchange Server 2007. This may explain whyMicrosoft finally brought Outlook to the Mac with Office 2010. So long,Outlook.
The Finder has been completely rewritten to support 64-bitoperation and take advantage of Grand Central Dispatch. This makes theFinder much more responsive.
For the first time, the Services menu is contextual: You will onlysee the services available to the current app. (Until now, half or moreof the Services might be grayed out because they don't work with yourcurrent program.)
Exposé can work in the Dock - click and hold an applicationicon and it will display that app's active documents in a grid. Appleclaims this will make it 'even easier to find what you're lookingfor.'
Time Machine backups are up to 50% faster, according to Apple. Thiswill be especially helpful for that first, long, full backup.
Macs shut down and wake up more quickly, and joining a WiFi networkis also faster. This makes for more energy efficient file sharing -your sleeping Mac uses less energy and wakes more quickly to serve upfiles.
If you travel with you're Mac, you'll appreciate automatic timezone settings.
The 'Wake on Demand' feature may keep your Mac from staying asleep.The fix is to reset the Energy Saver settings to their defaults, thenput in your own settings.

Things Lost with 10.6

There is no support for LocalTalk/AppleTalk in Snow Leopard. You'llneed to find another way to connect those old printers.
There is no longer any support for Palm OS devices in iSync. TheMissing Sync (commercial software) does support Palm devices.
Snow Leopard ignores creator codes when launching documents,something every Mac OS prior to 10.6 has supported - it's beenpart of the Mac OS since the beginning.
There is no write support for HFS+ volumes (floppies, hard drives,etc.)

Snow Leopard was replaced with OS X 10.7 Lion on July 20, 2011 afterjust 11 months at the helm.

Downloadable Updates

Standalone Updates let you update to a newer version of Mac OS Xfrom your hard drive instead of using Software Update, which requiresan Internet connection. Download the one(s) you need and install themafter mounting the disk image and launching the Installer program.

There are two types of Standalone Updates: Individual (or Delta) andCombo.

Individual Updates update one version of Mac OS X to thenext version. For example, the Mac OS X 10.6.4 Update updates Mac OS X10.6.3 to version 10.6.4. Individual Updates are also known as DeltaUpdates.
Combo Updates update the base version of a Mac OS X releaseto the version specified in the Combo Update, including allintermediate updates. For example, the Mac OS X 10.6.4 Combo Updateupdates any earlier version of Mac OS X 10.6 to Mac OS X 10.6.4 using asingle installer, as opposed to installing the individual Mac OS X10.6.1, 10.6.2, 10.6.3, and 10.6.4 updates.

Standalone Updates are generally available 24 to 48 hours after theUpdate is available through Software Update.

If you burn a Standalone Update to CD, its disk image must be copiedto your desktop or another location on your Mac OS X startup disk inorder to be installed.

This page will be updated as new Standalone Updates becomeavailable.

System Requirements for Snow Leopard vs Leopard

Snow Leopard (Mac OS X v10.6) only runs on Intel-based computers and not the older PowerPC chips.
An upgrade from Leopard to Snow Leopard frees up about 7GB of hard disk space. This has more to do with removing redundant components like printer drivers (which are downloaded on demand in Snow Leopard) than removing code specific to PowerPC.

Speed and Performance in Snow Leopard

Apple has made operating system components faster with Snow Leopard. Performance improvements include

Faster startup, shutdown, installation, Time Machine backup and connection establishment.
Faster PDF and JPEG icon refreshes.
Improved performance of Finder, which has been rewritten in 64-bit Cocoa

Refinements to the user interface in Mac OS X 10.6 (Snow Leopard)

There was no major overhaul of the existing Leopard interface when Apple introduced Snow Leopard. Minor UI refinements include:

Stacks in Snow Leopard allow viewing a subfolder without launching Finder. Stacks have also been modified to include scroll-bars for folders with many files.
Contextual menus which come out of Dock icons have more options and have a new look, with a semi-transparent charcoal background and white type.
Exposé can display all windows for a single program by left clicking and holding its icon in the dock.
Selection of columned text in PDF documents by analyzing the page layout.
Prefixes for bytes are now used in strictly decimal meaning when describing disk space, such that an indicated file size of 1 MB corresponds to 1,000,000 bytes.
There’s now a Put Back command in the Trash, just as in Windows’ Recycle Bin.
You can page through a PDF document or watch a movie right on a file’s icon.
When you click a folder icon on the Dock, you can scroll through the pop-up window of its contents.
Buggy plug-ins (Flash and so on) no longer crash the Safari Web browser; you just get an empty rectangle where they would have appeared.
Snow Leopard also has an impressive trove of tools for blind Mac users, including one that turns a Mac laptop’s trackpad into a touchable map of the screen; the Mac speaks each onscreen element as you touch it.
When you rename an icon on an alphabetically sorted desktop, it visibly slides into its new alphabetic position so you can see where it went.

New Features in Snow Leopard vs OS X Leopard

WiFi signal strength: AirPort in OS X Snow Leopard displays the signal strength for all available WiFi networks so you can choose the strongest possible connection.
Sortable search results: Snow Leopard adds the ability to sort Spotlight search results by name, date modified, date created, size, type of file, or label.
Annotations in Preview: New annotation tools in Preview allow users to annotate and markup PDF files, including comments, links, highlighting, strikethrough text, shapes, text, and arrows.
Cisco VPN support: Snow Leopard has built-in support for Cisco VPN connectivity. This allows users to connect securely with corporate networks (if the network uses Cisco VPN) without needing any additional software.
Automatic update for printer drivers: When connecting to a printer, Snow Leopard downloads the most current device driver for the printer from the Internet. The new OS X also periodically checks for updates to the printer driver via Software Update.
Nearby printers: When printing Snow Leopard displays the printers that are detected nearby, enabling you to identify and configure the best available device for printing your document.
HFS+ read in Boot Camp: When using Windows (via Boot Camp) users can now access (read-only) files on the 'Mac side' without rebooting.

Support for Microsoft Exchange

Mac OS X Snow Leopard includes out-of-the-box support for connecting to Microsoft Exchange 2007 servers for access through Mail, Address Book, and iCal. Neither Microsoft Windows nor older versions of Mac OS X included this feature.

64-bit addressing

Mac OS X Snow Leopard and most Mac OS 10.6 built-in applications have been rebuilt to leverage the 64-bit addressing space (excluding iTunes, Front Row, Grapher and DVD Player applications), since Apple has started shipping each Mac as a 64-bit system. Snow Leopard supports up to 16 terabytes of RAM.

Grand Central Dispatch in OS X v10.6

Grand Central Dispatch utilizes multiple processor cores for more efficient performance. Due to the technical difficulties involved in making multi-core-optimized applications, the majority of applications do not effectively utilize multiple processor cores. As a result, processing power often goes unused. Grand Central Dispatch includes APIs to help programmers efficiently use these cores for parallel programming.

OpenCL

Introduced in Snow Leopard, OpenCL (Open Computing Language) addresses the power of graphics processing units to leverage them in any application, and not just for graphics-intensive applications like 3D games. OpenCL automatically optimizes for the kind of graphics processor in the Mac, adjusting itself to the available processing power.

QuickTime X

In Mac OS X v10.6, Apple has redesigned the QuickTime user interface to resemble the existing QuickTime full-screen view, where the entire window plays only the video and all controls including the title bar fade in and out as needed.

QuickTime X supports HTTP live streaming. Thus, QuickTime X streams audio and video using any web server instead of a special streaming server, and it works reliably with common firewall and wireless router settings.

QuickTime X uses Mac OS X technologies such as Cocoa, Grand Central Dispatch, and 64-bit computing to deliver higher performance and enables QuickTime Player to launch up to 2.8x faster than QuickTime. QuickTime X also takes advantage of ColorSync to provide high-quality color reproduction.

There is a 'Send to YouTube' command built in when you play movies. Users can also record their screen activity as a movie.

CUPS

CUPS (the printing system in Mac OS X and Linux) has been updated to version 1.4 which provides improved driver, networking, and Kerberos support along with many performance improvements. CUPS 1.4 is also the first implementation of the Internet Printing Protocol version 2.1.
