I apologize if this has been covered before but as a new switcher to the Mac I was wondering if simply dragging a folder from Applications and deleting the preferences are enough for a complete uninstall. From years of working with Windows I've come to expect that programs cannot completely be removed even with uninstallers unless a manual search and destroy is initiated or a cleaner is used. Either the program would leave .dll files in the /system directory or there would be long-lived entries in the windows registry. Do any of these situations exist on the mac or have my years as a Windows user corrupted my thinking? Is there something akin to the registry on OS X?
