Apple has pushed out an update to the Snow Leopard version of the OS that adds new security guards against malware. It’s the first release in 10 months that improves this sort of hacker barrier.

If only the new iPad could be so lucky to be so well protected. We’ve been using the tablet since its release, but nary an update is to be downloaded to advance the device’s security.

The 10.6.4 version of Snow Leopard, which is a 17-minute download on a middle-fast DSL line, introduces new protection to prevent back door attacks on Macs through the iPhoto software that ships with every system.

Using the Dock, entering a Web address into Safari, composing email in Mail, locating files you’ve downloaded from the Web: it’s all shown screen by screen in Paul McFriederies’ book. The lessons are broken down into two-page spreads with alternative methods for some tasks, such as uninstalling applications or customizing the Dock. Read the rest of this entry »
