One of the greatest potential disadvantages with running an old version of OS X which is no longer maintained, is that it does contain security vulnerabilities. Apple discontinued support for 10.8 in October 2015, for 10.7 in October 2014, and for 10.6 in February 2014. Anything earlier than that, including 10.6 (Snow Leopard), is unsupported and no longer receives security patches.

As of November 2015, this includes 10.11 (El Capitan), 10.10 (Yosemite), and 10.9 (Mavericks). Away from the enticing displays and glitz of Apple’s stores, many users are still running versions as old as 10.6.8 – sometimes even older – and have neither the desire nor the budget to change.Īside from problems keeping older hardware running, Apple’s official line is that you should only run versions of OS X which are still supported. We cannot all run the latest Mac and the latest version of OS X.
