Apple looks to be stepping up the frequency of OS X Mountain Lion beta updates after initially keeping the pace slow and steady: it just posted a new, unceremoniously titled 12A206J build for developers. What the update fixes in the Developer Preview isn't clear, but there are still glitches with Fast User Switching, Java applets, sharing menus and Notes syncing with iTunes, among a handful of other showstoppers. There's also a major heads-up for those who own mid-2007 MacBook Pros, as they can't properly run Mountain Lion at all until another update. We wouldn't be surprised if there's another fix in store ahead of WWDC next month, and there's still all of the summer left for Apple to put the final polish on the OS and make its release target.
