On Friday, Apple gave its developers a holiday-weekend treat by seeding the third build of Mac OS X 10.6.8. Not much is known about the 1GB download (labeled 10K531), although key areas of concentration for the beta software look unrevised: Mac App Store, Airport, Graphics Drivers, Networking, QuickTime and VPN.

For now, it appears that Apple is remaining consistent with a weekly release schedule for its developer builds of Mac OS X. Fourteen days ago, we received the first. And just last week, the second build came like clockwork. Now, here we are, late on a Friday talking about the third build of Mac OS X 10.6.8.

I've already been pegged with questions regarding whether Mac OS X 10.6.8 somehow addresses the MACDefender malware - specifically, the capability to find and remove the nefarious presence. Unfortunately, the release is so fresh we don't yet have an answer to that question, although we're expecting some form of response to MACDefender. Earlier this week, my MMi colleague Joshua Tucker reported that a strong possibility existed for a malware fix to come with Mac OS X 10.6.8.

In a matter of weeks, Apple will be primed and ready for the summertime roll-out of the next major upgrade to its flagship operating system - Mac OS X 10.7 Lion, something we're bound to hear a thing or two about a WWDC, which begins in just ten days.
