It seems that Apple is working hard on the Mac OS X front. In addition to the updated DP3 version of Mountain Lion, a new version of Mac OS X 10.7.4, aka 11E53 is also available for download for developers. The previous version 11E52 was seeded couple of weeks ago, so it seems that Apple has quickly reacted to fix reported bugs, if any has been reported. This new version might be pushed as the final 10.7.4 is not further/new bugs are sent back by developers.
