Apple may be working on a Mac OS X 10.6.9 update to extend iCloud to Snow Leopard, an error message reveals. After upgrading a MobileMe account to iCloud, one developer says he encountered a unique error message in Tiger's .Mac preferences pane. "You will no longer be able to sync with this machine because you've upgraded to iCloud," it begins. "iCloud requires running Mac OS X Snow Leopard v10.6.9 or later for Contacts, Calendars, and Bookmarks."
