Defaults Manager is an editor for the User Defaults preferences database on Mac OS X. It allows you to easily view, edit, delete, and backup preferences, and can be used to view and change the preferences in almost any application. It is useful for developers that want to make sure their preferences are being stored and changed correctly, and can be used to unlock features that previously required the use of Terminal.
SafeClean quickly removes Internet history files, caches, bookmarks, email, and conversation logs that can allow others to find out what you have been doing on the Internet, possibly revealing personal and potentially compromising information. It allows you to permanently destroy information about your Web browsing activities, private email messages, and even information on your use of Instant Messenger programs. It is easy to use, and provides a one-click method to protect your Internet privacy. For power users, SafeClean is completely configurable so that you can decide which types of information or which Internet applications you wish to clean for privacy purposes.
