Hmm, 20mb for 10.8, and a hefty 347mb for 10.6
That's the normal pattern. When Apple releases a security update it usually incorporates earlier security updates going back to the last minor system version number update (which incorporated all security updates prior to that point), so that people installing the system from scratch only need to apply a single system version update followed by a single security update, instead of multiple security updates.
This means that security updates are generally larger for older major system versions, because they have had a longer time since the last minor version number update, and more security updates have accumulated.
Snow Leopard has been accumulating security updates since 10.6.8 was released in June 2011.
Lion has been accumulating security updates since 10.7.5 was released in September 2012.
Mountain Lion's security update only needs to include this batch of fixes, since all earlier ones are included in 10.8.4, which was released in June 2013.
Nothing for Snow Leopard? What does it fix exactly?
Did you actually read anything or did you jump straight to comment? Jack wagon...
