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.
