For the first time, the pre-release version, labeled build 11C55, does not require a separate install of iCloud services. No known issues are listed for the beta. Apple reportedly lists iCloud, Address Book, iCal, Mail, Safari, and MobileMe as focus areas for the release.
One person familiar with the matter also indicated that Apple has begun transitioning user accounts from MobileMe to iCloud, allowing the transfer of mail, contacts, and calendars to the iCloud.com.
The last beta release of Mac OS X 10.7.2 came on Sept. 2 and included the 10th test version of iCloud as a separate install.
Developers have seen a steady stream of beta software as Apple gears up for several major releases this fall. The launch of iOS 5 and iCloud will be supported by updated versions of iTunes and Mac OS X. Last Friday, Apple issued a beta release of iTunes 10.5, along with pre-release versions of iWork for iOS. The company also recently extended the test period of its iTunes Match service to additional developers.
Apple launched Mac OS X 10.7 Lion on the Mac App Store in July. The company then updated its flagship desktop operating system to version 10.7.1 in August, adding improvements to Wi-Fi and audio out functionality.
