Lion beta 11C55 turns on full iCloud
Apple gave developers a full view of iCloud integration in Mac OS X for the first time with an unusual Sunday release of a new Mac OS X 10.7.2 beta. The new 11C55 build already includes iCloud instead of requiring a separate install, like in earlier releases. No known bugs exist with the build, but users are expected to test both iCloud itself as well as Address Book, iCal, Mail, Safari, and legacy MobileMe support.
Focuses are also placed on the Mac App Store, Spotlight, Time Machine, and video drivers.
The appearance on Sunday, along with its arriving just two days after new iTunes and iWork for iOS betas, points to Apple being at the very last stages of development. Most expect Apple to ship an iPhone 5 in early October, and to accomplish this it's likely to want Lion, iOS 5, and as many apps as possible ready to use iCloud at the same time.
Other signs have emerged that Apple is wrapping up. It just recently began expanding iTunes Match beta subscriptions.
