Apple has seeded OS X Lion 10.7.4 to registered developers following the release of the second Mountain Lion developer preview this afternoon. Lion 10.7.4 can be downloaded now in the Mac Dev Center. The release weighs in at 1.33 GB for the combo update and 580 MB for the delta version.
10.7.4 (Build 11E27) will be deployed to the public once Apple gets the kinks ironed out with developers. A server version of Lion has also been seeded to accompany 10.7.4. The last version of Lion to go public was 10.7.3 at the beginning of February. A supplemental update was released last week to solve an issue with malfunctioning Time Machine backups.
