As some of you will notice, 10.6 Snow Leopard has received no updates whatsoever. Snow Leopard users are stuck with Safari 5.1 and while this version is still able to load any website, using a browsers with known vulnerabilities is a risk. With the majority of adware/spyware/malware entering systems through the browser and Apple apparently finally giving up support for Snow Leopard, users of that OS X version are recommended to switch browsers. Firefox would be an excellent choice as it’s latest versions support OS X 10.6 and up so even older OS versions will benefit from the latest security patches and enhancements.

While it is recommended to upgrade to the latest OS X version for security reasons, not everyone can or wants to. If you run OS X 10.6 and your hardware allows it, consider upgrading. If you don’t want to, at least consider upgrading to a newer version like OS X 10.8 and if you want to upgrade but can’t due to hardware limitations, consider adding more RAM to your Mac (as this is the most common reason people can’t update).
OS X 10.9 Mavericks system requirements can be found here. The requirements for 10.8 Mountain Lion are identical.
