Apple Retires Support Leaving 20% Of Macs Vulnerable

Keep on Guard!


There’s been a lot of news and scrambling lately related to the Apple SSL vulnerability, and this week Apple announced it would no longer be supporting OS X 10.6 AKA Snow Leopard.

It looks like Lion and Mountain Lion will be supported for a while, and an upgrade to Mavericks is free, so there’s no real reason not to.

The free upgrade path seems to be working fairly well for them, with 42% of all versions of OS X used in January being attributed to Mavericks.

Apple on Tuesday made it clear that it will no longer patch OS X 10.6, aka Snow Leopard, when it again declined to offer a security update for the four-and-a-half-year-old operating system.

As Apple issued an update for Mavericks, or OS X 10.9, as well as for its two predecessors, Mountain Lion (10.8) and Lion (10.7), Apple had nothing for Snow Leopard or its owners yesterday.

Snow Leopard was also ignored in December, when Apple patched Safari 6 and 7 for newer editions of OS X, but did not update Safari 5.1.10, the most-current Apple browser for the OS.

Apple delivered the final security update for Snow Leopard in September 2013.

Traditionally, Apple has patched only the OS X editions designated as “n” and “n-1” — where “n” is the newest — and discarded support for “n-2” either before the launch of “n” or immediately after. Under that plan, Snow Leopard was “n-2” when Mountain Lion shipped in mid-2012, and by rights should have been retired around then.

But it wasn’t. Instead, Apple continued to ship security updates for Snow Leopard, and with Tuesday’s patches of Mountain Lion and Lion Tuesday, it now seems plain that Apple has shifted to supporting “n-2” as well as “n” and “n-1.”

(In that scenario, Mavericks is now “n,” Mountain Lion is “n-1” and Lion is “n-2.”)

The change was probably due to Apple’s accelerated development and release schedule for OS X, which now promises annual upgrades. The shorter span between editions meant that unless Apple extended its support lifecycle, Lion would have fallen off the list about two years after its July 2011 launch.


Apple only used to support the current product and the release before that, but Snow Leopard has been supported far longer than that – which indicates they are now probably supporting the current release and the two before that.

Though they haven’t really released any formal statements about support, end of life procedures or timelines. They do have an accelerated release timeline now so it does make sense for them to support more previous releases.

None of this would be noteworthy if Apple, like Microsoft and a host of other major software vendors, clearly spelled out its support policies. But Apple doesn’t, leaving users to guess about when their operating systems will fall off support.

“Let’s face it, Apple doesn’t go out of their way to ensure users are aware when products are going end of life,” said Andrew Storms, director of DevOps at security company CloudPassage, in a December interview.

To Apple, Snow Leopard increasingly looks like Windows XP does to Microsoft: an operating system that refuses to roll over and die. At the end of January, 19% of all Macs were running Snow Leopard, slightly more, in fact, than ran its successor, Lion, which accounted for 16%, and almost as much as Mountain Lion, whose user share plummeted once Mavericks arrived, according to Web analytics firm Net Applications.

With Snow Leopard’s retirement, 1 in 5 Macs are running an operating system that could be compromised because of unpatched vulnerabilities.

Snow Leopard users have given many reasons for hanging on, including some identical to those expressed by Windows XP customers: The OS still works fine for them; their Macs, while old, show no sign of quitting; and they dislike the path that Apple’s taken with OS X’s user interface (UI).

If Apple really wants more corporate/enterprise support – they really need to come out with some formal policies for support and end of life. Also they could really use some enterprise level tools for delivering patches/OS upgrades.

On top of that we also have a whole lot of people who choose not to upgrade for whatever reason (the same folks still using Windows XP) – who will become vulnerable at some point.

    There is _one_ reason not to upgrade to Mavericks. It runs like crap on older hardware. My 4 year old Mac Mini runs slow as a dog with Mavericks.

      Ah, I say install OpenELEC on it and use it as a media centre :D
