Snow Leopard had received a security update in September of 2013, just two months earlier.
To be clear, Snow Leopard does not appear to have the "gotofail" bug -- the SSL/TLS vulnerability allowing secure web sessions to be hijacked with a man in the middle attack -- which was patched in Mavericks this week and in i OS before that.
The bad news is that if a vulnerability is found, there's really no guarantee Apple will patch it.
As for Lion or Mountain Lion fans worried their OS may be the next on the chopping block, rest easily.
You may experience unexpected results if you have third-party system software modiﬁcations installed, or if you've modiﬁed the operating system through other means.
The writing was on the wall for Snow Leopard in December 2013 when Apple patched Safari for OS X Lion, Mountain Lion, and Mavericks without thinking about their older sibling.Now that it seems Apple's finally ended support for Mac OS X Snow Leopard 10.6, its fourth-oldest operating system, it's time for users to upgrade.Using an unsupported operating system means that Apple will no longer release security patches and other software fixes, leaving it vulnerable to hackers.Note that an update's size may vary from computer-to-computer when installed using Software Update.Also, some updates must be installed prior to others, so you should run Software Update more than once to make sure you have all available updates. This is a useful option when you need to update multiple computers but only want to download the update once.
