Following yesterday’s update to OS X Mountain Lion Developer Preview 3, Apple has now issued the fourth developer preview of OS X Mountain Lion Server to registered Mac developers. The update carries a build number of 12S219n.
It’s unclear why Apple didn’t simply issue an update to Mountain Lion Server DP3, as they did with the Mountain Lion developer preview. In fact, it seems strange for Apple to seed Mountain Lion Server as Developer Preview 4 while keeping the base OS as Developer Preview 3.
The update is available now as a Mac App Store redeem code, which can be obtained from Apple’s developer portal.
