Mac OS X 10.6.8 build preps for upgrading to Lion
A third test build of Mac OS X 10.6.8 has surfaced this weekend and produced a discovery confirming Apple's plans to offer Lion through the Mac App Store. New notes added for the release mention that it's intended to "enhance" the store to "get your Mac ready to upgrade to Mac OS X Lion." It's unclear from Florian Schimanke's sighting what those changes might be.
An upgrade path to Lion was anticipated given that Lion betas were distributed to developers and references that had been seen in the past. Until now, however, it hadn't been apparent whether any special changes would be needed. Mac users will most likely need 10.6.8 as a minimum requirement to upgrade to Lion through a downloadable copy and will have to buy a disc if using an earlier OS.
Apple is expected to show Lion at WWDC and may even consider the OS finished or close to it by the time the developer event starts on June 6. The option of a download could not only give users a faster track than waiting for a hard copy but let Apple offer a discounted price for downloaders.
Along with the Lion upgrade prep, the 10.6.8 build notes confirm that 10.6.8 will detect and scrub MacDefender. The patch should also fix random crashes in Preview as well as bolster IPv6 and VPN networking.
