Many Macs are vulnerable due to publicized but unpatched security issues with Safari. Square Circle Consulting, LLC recommends the following for users running versions of OS X prior to Lion:
- Switch to a browser that’s being kept up-to-date, such as Firefox, and stop using Safari.
- Select Apple menu->Software Update… and install all security-related updates such as Security Update 2012-004 and Java for Mac OS X 10.6 Update 10.
- Run up-to-date commercial anti-virus software.
- Prepare to upgrade to OS X 10.7 Lion or 10.8 Mountain Lion.
Historically, Apple has only released comprehensive security updates for the current and previous versions of Mac OS X. The day after the release of OS X 10.8 Mountain Lion, a Safari update was released which patched a wide variety of security issues in OS X 10.7 Lion, but not in Mac OS X 10.6 Snow Leopard or earlier versions of OS X.
This seemed to follow the typical pattern of things, but 10.7 had only been out for a year, so we hoped that Apple would extend support for 10.6, given that half of all Macs run 10.6 or older. In September, Apple released a Java update for 10.6 and comprehensive security updates for 10.6, 10.7 and 10.8. Another Safari update was also released, but only for 10.7 and 10.8.
