John Siracusa - Sep 1, 2009 3:00 am UTC.

In June of 2004, during the WWDC keynote address, Steve Jobs revealed Mac OS X 10.4 Tiger to developers and the public for the first time. When the finished product arrived in April of 2005, Tiger was the biggest, most important, most feature-packed release in the history of Mac OS X by a wide margin. Apple's marketing campaign reflected this, touting 'over 150 new features.'

All those new features took time. Since its introduction in 2001, there had been at least one major release of Mac OS X each year. Tiger took over a year and a half to arrive. At the time, it definitely seemed worth the wait. Tiger was a hit with users and developers. Apple took the lesson to heart and quickly set expectations for the next major release of Mac OS X, Leopard. Through various channels, Apple communicated its intention to move from a 12-month to an 18-month release cycle for Mac OS X. Leopard was officially scheduled for 'spring 2007.'

As the date approached, Apple's marketing machine trod a predictable path.

Apple even went so far as to list all 300 new features on its website. As it turns out, 'spring' was a bit optimistic. Leopard actually shipped at the end of October 2007, nearly two and a half years after Tiger. Did Leopard really have twice as many new features as Tiger? That's debatable. What's certain is that Leopard included a solid crop of new features and technologies, many of which we now take for granted. (For example, have you had a discussion with a potential Mac user since the release of Leopard without mentioning Time Machine? I certainly haven't.)


Mac OS X appeared to be maturing. The progression was clear: longer release cycles, more features. What would Mac OS X 10.6 be like? Would it arrive three and a half years after Leopard? Would it and include 500 new features? A thousand?

At WWDC 2009, Bertrand Serlet announced a move that he described as 'unprecedented' in the PC industry.

That's right, the next major release of Mac OS X would have no new features. The product name reflected this: 'Snow Leopard.' Mac OS X 10.6 would merely be a variant of Leopard. Better, faster, more refined, more... uh... snowy.


This was a risky strategy for Apple. After the rapid-fire updates of 10.1, 10.2, and 10.3 followed by the riot of new features and APIs in 10.4 and 10.5, could Apple really get away with calling a 'time out?' I imagine Bertrand was really sweating this announcement up on the stage at WWDC in front of a live audience of Mac developers. Their reaction? Spontaneous applause. There were even a few hoots and whistles.

Many of these same developers applauded the '150+ new features' in Tiger and the '300 new features' in Leopard at past WWDCs. Now they were applauding zero new features for Snow Leopard? What explains this?

It probably helps to know that the '0 New Features' slide came at the end of an hour-long presentation detailing the major new APIs and technologies in Snow Leopard. It was also quickly followed by a back-pedaling ('well, there is one new feature...') slide describing the addition of Microsoft Exchange support. In isolation, 'no new features' may seem to imply stagnation. In context, however, it served as a developer-friendly affirmation.


The overall message from Apple to developers was something like this: 'We're adding a ton of new things to Mac OS X that will help you write better applications and make your existing code run faster, and we're going to make sure that all this new stuff is rock-solid and as bug-free as possible. We're not going to overextend ourselves adding a raft of new customer-facing, marketing-friendly features. Instead, we're going to concentrate 100% on the things that affect you, the developers.'

But if Snow Leopard is a love letter to developers, is it a Dear John letter to users? You know, those people that the marketing department might so crudely refer to as 'customers.' What's in it for them? Believe it or not, the sales pitch to users is actually quite similar. As exhausting as it has been for developers to keep up with Apple's seemingly never-ending stream of new APIs, it can be just as taxing for customers to stay on top of Mac OS X's features. Exposé, a new Finder, Spotlight, a new Dock, Time Machine, a new Finder again, a new iLife and iWorkalmost every year, and on and on. And as much as developers hate bugs in Apple's APIs, users who experience those bugs as application crashes have just as much reason to be annoyed.

Enter Snow Leopard: the release where we all get a break from the new-features/new-bugs treadmill of Mac OS X development. That's the pitch.

Uncomfortable realities

But wait a second, didn't I just mention an 'hour-long presentation' about Snow Leopard featuring 'major new APIs and technologies?' When speaking to developers, Apple's message of 'no new features' is another way of saying 'no new bugs.' Snow Leopard is supposed to fix old bugs without introducing new ones. But nothing says 'new bugs, coming right up' quite like major new APIs. So which is it?


Similarly, for users, 'no new features' connotes stability and reliability. But if Snow Leopard includes enough changes to the core OS to fill an hour-long overview session at WWDC more than a year before its release, can Apple really make good on this promise? Or will users end up with all the disadvantages of a feature-packed release like Tiger or Leopard—the inevitable 10.x.0 bugs, the unfamiliar, untried new functionality—but without any of the actual new features?

Yes, it's enough to make one quite cynical about Apple's real motivations. To throw some more fuel on the fire, have a look at the Mac OS X release timeline below. Next to each release, I've included a list of its most significant features.

That curve is taking on a decidedly droopy shape, as if it's being weighed down by the ever-increasing number of new features. (The releases are distributed uniformly on the Y axis.) Maybe you think it's reasonable for the time between releases to stretch out as each one brings a heavier load of goodies than the last, but keep in mind the logical consequence of such a curve over the longhorn haul.

And yeah, there's a little upwards kick at the end for 10.6, but remember, this is supposed to be the 'no new features' release. Version 10.1 had a similar no-frills focus but took a heck of a lot less time to arrive.

Looking at this graph, it's hard not to wonder if there's something siphoning resources from the Mac OS X development effort. Maybe, say, some project that's in the first two or three major releases of its life, still in that steep, early section of its own timeline graph. Yes, I'm talking about the iPhone, specifically iPhone OS. The iPhone business has exploded onto Apple's balance sheets like no other product before, even the iPod. It's also accruing developers at an alarming rate.

It's not a stretch to imagine that many of the artists and developers who piled on the user-visible features in Mac OS X 10.4 and 10.5 have been reassigned to iPhone OS (temporarily or otherwise). After all, Mac OS X and iPhone OS share the same core operating system, the same language for GUI development, and many of the same APIs. Some workforce migration seems inevitable.

And let's not forget the 'Mac OS X' technologies that we later learned were developed for the iPhone and just happened to be announced for the Mac first (because the iPhone was still a secret), like Core Animation and code signing. Such conspiracy theories certainly aren't helped by WWDC keynote snubs and other indignities suffered by Mac OS X and the Mac in general since the iPhone arrived on the scene. And so, on top of everything else, Snow Leopard is tasked with restoring some luster to Mac OS X.

Got all that? A nearly two-year development cycle, but no new features. Major new frameworks for developers, but few new bugs. Significant changes to the core OS, but more reliability. And a franchise rejuvenation with few user-visible changes.

It's enough to turn a leopard white.

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.

Minimum Hardware Requirements

  • Intel-based Mac
  • 1 GB of RAM, although 2 GB is strongly recommended
  • 5 GB of available drive space
  • DVD-compatible optical drive
  • Grand Central Dispatch requires a dual-core CPU
  • 64-bit support requires a Core 2 or newer CPU
  • OpenCL is compatible with all current Macs. It is not compatiblewith:
    • iMacs released before March 2009
    • Mac mini released before March 2009
    • MacBook released before October 2008
    • MacBook Pro released before June 2007
    • Mac Pro released before January 2008 (Jan. 2008 and later modelswith unsupported video cards can used the discontinued GeForce 8800upgrade kit - Apple part no. MB137Z/A - for OpenCL support. The GeForce GT 120 retails for $149, is designed to work with the 2009Mac Pro and has been reported to work with the 2008 model as well.)

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.

Mac OS X Snow Leopard - Wikipedia

  • 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.
