Following last week's seed of the first developer build of Mac OS X 10.6.8, Apple has now pushed out a second version known as Build 10K524.
With the update checking in as a 1 GB download, developers are reportedly being asked to focus their testing on AirPort, Graphics Drivers, Mac App Store, Networking, QuickTime and VPN, the same areas highlighted in the initial developer build last week.
As we have previously noted, Apple is expected to make Mac OS X Lion a major focus of its Worldwide Developers Conference (WWDC) scheduled for just a few weeks from now. Apple has pegged the public launch of the next-generation operating system for "summer", although a more specific timeframe is not yet known. Consequently, Mac OS X 10.6.8 may be the final update for Snow Leopard before Lion debuts.
