Apple Rolls iCloud Beta into New OS X 10.7.2 Build 11C55

Apple today seeded a new version of OS X 10.7.2, termed Build 11C55, to developers. Notably, the build appears to fully incorporate iCloud functionality for the first time. The iCloud components had previously been included as a separate download to be installed on top of earlier OS X 10.7.2 builds.

OS X Lion Software Update 10.7.2 is an update to OS X Lion 10.7 and includes support for iCloud beta. Please refer to the seed note for more details and installation instructions.

The new build comes nine days after the previous seed of OS X 10.7.2 Build 11C48 with the associated iCloud beta 10.

Apple continues to list no known issues with the latest build, and asks developers to focus their testing on AddressBook, GraphicsDrivers, iCal, iChat, iCloud, Mac App Store, Mail, MobileMe, Safari, Spotlight, and Time Machine.

Just this past Friday, Apple seeded new developer builds of iTunes 10.5 and iWork for iOS as part of continued testing for iCloud compatibility. The company has also been seeding builds of iPhoto 9.2 to support the Photo Stream component of iCloud, but has not seeded a new iPhoto build since August 26th.

Apple is of course also continuing to seed iOS developers with builds of iOS 5 leading up to the public launch of the next-generation operating system for Apple's mobile devices. The current developer seed is iOS 5 beta 7, released on August 31st.
