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.
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 retires Snow Leopard from support, leaves 1 in 5 Macs vulnerable to attacks
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.
