Apple has issued a new software update via the Mac App Store to Mountain Lion Developer Preview 4. This update was originally released last week.
This update is the second time Apple has updated the Mountain Lion Developer Preview via the Mac App Store rather than releasing an entirely new Developer Preview (DP). Apple issued a similar update in May.
Apple did not specify changes in the update. The Mac-maker said that it “is recommended for all users running OS X Mountain Lion Developer Preview 4.” With Mountain Lion’s final release expected next month, it is time when Apple should be moving towards a final build soon.
Among other things, the latest update adds support for more Facebook notifications and PowerNap support for supported machines. Its size is 1.08GB and it has a build number of 12A248, up from 12A239 previously.
