Apple goes against grain, extends support for Snow Leopard
Apple yesterday quietly released a security update for OS X 10.6, aka Snow Leopard, effectively extending support for the three-year-old OS beyond the normal lifecycle.
The Snow Leopard update shipped alongside larger updates for Lion and Mountain Lion, OS X 10.7 and OS X 10.8.
Snow Leopard patches were unexpected. In the past, Apple has stopped serving security updates for one edition around the time it has two newer in play. If the current OS X is dubbed "n," then "n-2" support ends at the debut of "n." In that scenario, Mountain Lion, which Apple launched in July, serves as "n," and 2009's Snow Leopard is "n-2."
