In 10.7.2, Apple set the iCloud sign-in to pop up on the first login. Since having this appear may not be desirable in all Mac environments, it makes sense to be able to turn this off for new user accounts. After doing some file tracking, Mike Boylan and Allen Golbig figured out which file controlled this.etting com.apple.SetupAssistant.plist in /System/Library/User\ Template/Non_localized/Library/Preferences/ to include the key DidSeeCloudSetup with a Boolean value of TRUE will stop the iCloud login from automatically coming up for new users.
