Apple Insider said that developers were requested to install Mac OS X 10.7.2 build 11C26 over the weekend in order to put iCloud for Lion beta 5 through its paces.
The report notes that the request seems somewhat unusual given that no developer previews of Mac OS X 10.7.1 have yet been issued.
“You must install OS X Lion 10.7.2 in order to use iCloud for OS X Lion beta 5. This pre-release version of OS X Lion is being provided solely for testing iCloud,” Apple told developers, according to Apple Insider.
It is thought that there will be a Mac OS X 10.7.1 issued in the coming weeks to address some of the known issues in Lion.
Mac OS X 10.7.2 doesn’t address any of these issues but does update the Mail, Contacts and Calendars control panel with an iCloud management interface that lets users set sync preferences.
Versions of iCloud for Lion and iOS 5 are due to be released in spring.
