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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

Apple delivered the final security update for Snow Leopard in September 2013.<\/p>\n

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.<\/p>\n

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.”<\/p>\n

(In that scenario, Mavericks is now “n,” Mountain Lion is “n-1” and Lion is “n-2.”)<\/p>\n

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.<\/p><\/blockquote>\n
