The latest update of Lion for Mac OS X 10.7.2 comes with an interesting new option, where it prompts users to log into iCloud. This setting is stored in com.apple.SetupAssistant.plist in the DidSeeCloudSetup key. Configuring the boolean with a positive value then suppresses the prompt for the user:
defaults write /System/Library/User Template/Non_localized/Library/Preferences/com.apple.SetupAssistant DidSeeCloudSetup -boolean YES
If you have configured it and you want to run it again, just revert to NO:
defaults write /System/Library/User Template/Non_localized/Library/Preferences/com.apple.SetupAssistant DidSeeCloudSetup -boolean NO
These commands can be sent out through Apple Remote Desktop, or some other patch management system.
