1. Apr 23, 2012 Everything since the release of Snow Leopard has been 'Intel-Only'.that was one of the main features of the Snow Leopard release in the first place. Certainly Lion also has the PPC code removed.there really wouldn't be a point of putting it back in after it was removed. Apple doesn't do that! OS 10.5 'Leopard' was the last OS to have PPC code.
  2. Nov 04, 2011 The Snow Leopard version of Mac OS X released in 2009 was widely hailed by Mac users. The version was leaner, much faster and more thoroughly integrated with applications than ever before.

Jul 20, 2011 Although Snow Leopard only ran on Intel machines, Lion drops Rosetta support, meaning any software written for the PowerPC architecture will no longer work at all. If you still use any of these.


Mac OS X Snow Leopard is renowned for its simplicity, its reliability, and its ease of use. So when it came to designing Snow Leopard, Apple engineers had a single goal: to make a great thing even better. They searched for areas to refine, further simplify, and speed up — from little things like ejecting external drives to big things like installing the OS. In many cases, they elevated great to amazing. Here are just a few examples of how your Mac experience was fine-tuned.


Apple Snow Leopard Os


  • 64 Bit
    64-bit computing used to be the province of scientists and engineers, but now this generational shift in computing gives all users the tools to apply the power of 64-bit to speed up everything from everyday applications to the most demanding scientific computations. Although Mac OS X is already 64-bit capable in many ways, Snow Leopard takes the next big step by rewriting nearly all system applications in 64-bit code¹ and by enabling the Mac to address massive amounts of memory. Now Mac OS X is faster, more secure, and completely ready for the future.
  • Grand Central Dispatch
    More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central Dispatch takes full advantage by making all of Mac OS X multicore aware and optimizing it for allocating tasks across multiple cores and processors. Grand Central Dispatch also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems.
  • Open CL
    With graphics processors surpassing speeds of a trillion operations per second, they’re capable of considerably more than just drawing pictures. OpenCL in Snow Leopard is a technology that makes it possible for developers to tap the vast gigaflops of computing power currently in the graphics processor and use it for any application.
  • QuickTime X
    Snow Leopard introduces QuickTime X, a major leap forward that advances modern media and Internet standards. QuickTime X includes a brand-new player application, offers optimized support for modern codecs, and delivers more efficient media playback, making it ideal for any application that needs to play media content.
  • Faster, more powerful Safari.
    Safari renders web pages at high speed and delivers a range of new features, including full history search, smart address and search fields, an innovative way to display your top sites, industry-leading support for web standards, and more.
    With Snow Leopard, Safari delivers up to 50 percent faster JavaScript performance thanks to its 64-bit support.6 In addition, Safari is even more resistant to crashes. It turns out that the number one cause of crashes in Mac OS X is browser plug-ins. So Apple engineers redesigned Safari to make plug-ins run separately. If a plug-in crashes on a web page, Safari will keep running.
  • Out of the Box Support for Microsoft Exchange
    With Snow Leopard, the Mac is the only computer with built-in support for Microsoft Exchange Server 2007. So you can use your Mac — with all the features and applications you love — at home and at work and have all your messages, meetings, and contacts in one place.

General requirements

  • Mac computer with an Intel processor
  • 1GB of memory
  • 5GB of available disk space
  • DVD drive for installation
  • Some features require a compatible Internet service provider
  • Some features require Apple’s MobileMe service

NetMarketShare released its February 2012 online market share data with some interesting data for the month.

  • On PCs, only OS X increased share.
  • On Macs, OS X 10.6 Snow Leopardincreased its share and remains ahead of OS X 10.7 Lion.
  • iOS increased its share of the mobile market from under 54% to over 60%. Android is a distant second at just over 19%, displacing JavaME for second place.

It’s nice to see Apple dominate in the mobile space, and it’s great to see OS X was the only operating system to gain PC market share in February, but I find the growth of Snow Leopard the most interesting piece of data.

Last July, OS X 10.7 Lion hit the market with 0.33% market share, and Snow Leopard peaked at 4.0%. But as Lion gained market share, it was only partially at the expense of Snow Leopard. For instance, in August, 10.7 added 0.70% while 10.6 lost only 0.54%. Snow Leopard hit a low of 2.95% in January and bounced back to 3.0% in February – something very unusual for a discontinued operating system (the same thing happened last October).

That said, Lion has continued its steady growth and now has 2.69% market share. At its current rate of growth, it should finally pass Snow Leopard this month.

What’s most intriguing is that while all new Macs sold since last summer have shipped with OS X 10.7 Lion and the upgrade has been available for just $30, 75% of Snow Leopard users have not made the switch – and based on Snow Leopard increases in October and February, it appears that some who switched to Lion have gone back to Snow Leopard.

This does not bode well for Apple, which depends on Mac users migrating to the latest version of the Mac OS that their hardware supports. Most of those Snow Leopard Macs are capable of running Lion, and the few that can’t were all Core Solo and Core Duo models introduced in 2006.

As a Snow Leopard user who has not installed Lion and doesn’t plan on it, I can venture two solid reasons for OS X 10.6 users to stick with Snow Leopard:

  1. Losing Rosetta and the ability to run PowerPC apps.
  2. Big changes in OS X Lion that depend on new software to work (for instance, Versions and AutoSave).

For the most part, it boils down to money. Why should I pay $30 to upgrade to Lion when it means my old copy of Photoshop or Microsoft Office or AppleWorks won’t work? With Photoshop and Office, there are newer versions available, but for AppleWorks, there really is no substitute. Granted, Apple’s iWork suite has the same functionality and early versions can import AppleWorks files, but Pages and Numbers are completely different apps compared to AppleWorks.

Even if all of your apps run natively on Intel Macs, there’s the matter of getting new versions that will take advantage of the new Lion features. Sometimes those updates are free, but sometimes you have to pay for a version update to get the Lion features, making OS X 10.7 much more than a $30 upgrade.

A lot of us have drawn a line in the sand. We have Macs that work perfectly well with OS X 10.6 Snow Leopard (likewise for PowerPC Macs with OS X 10.5 Leopard and 10.4 Tiger), and moving ahead with Apple comes at too high a cost in terms of finances, familiarity, and productivity.

I have no disdain for Lion users, and some Low End Mac staffers use and love it. It’s just that many of us are longtime Mac users with years or decades invested in buying and using software that just works for us. Moving to a version of OS X that breaks those apps just isn’t an option.

In fact, we’re seeing something of a Lion backlash among low-end Mac users, as they look for new, refurbished, and recently discontinued Macs that are still capable of booting Snow Leopard so they can remain productive without having to enter the strange new world of Lion.

It’s great to see Mac OS X gaining market share, and it’s wonderful to see so many users embracing Lion (and, later this year, sure to embrace OS X 10.8 Mountain Lion), but it’s also good to know that our old Macs are going to remain productive with our older operating systems and apps for years to come.
