iTunes iTunes is a media player, media library, Internet radio broadcaster, mobile device management utility, and the client app for iTunes Store. It is used to purchase, play, download, and organize digital multimedia, on personal computers running the macOS and Windows operating systems. iTunes is developed by Apple Inc. It was announced on January 9, 2001. Because iTunes was criticized for having a bloated user experience, Apple decided to split iTunes into separate apps as of macOS Catalina: Apple Music, Apple Podcasts, and Apple TV. Finder would take over the device management aspect that iTunes previously served. This change would not affect Windows or older macOS versions. Network Utility Network Utility was an application for macOS up to MacOS Catalina that provided a variety of tools that could be used related to computer network information gathering and analysis. Starting with macOS Big Sur the application is no longer included and was replaced with a message that it has been deprecated. Starting with macOS Ventura, the application is removed from the OS. Network Utility showed information about each of your network connections, including the MAC address of the interface, the IP address assigned to it, its speed and status, a count of data packets sent and received, and a count of transmission errors and collisions. It also provided a GUI to the netstat, ping, traceroute, whois, finger, and stroke UNIX programs. ODBC Administrator ODBC Administrator was a 32-bit utility in the Mac OS X operating system for administering ODBC, which enables interaction with ODBC-compliant data sources. Features included connection pooling, trace log creation, and ODBC driver management, among other administration features. Although Apple started including the underlying iODBC libraries in Mac OS X Jaguar, and continued to do so through at least macOS Big Sur, Apple only included their ODBC Administrator through Mac OS X Leopard, and temporarily made it available as a separate download (since removed) for Snow Leopard. Alternatives to Apple's 32-bit ODBC Administrator include the free and open source 32-bit and 64-bit iODBC Administrator included with the iODBC SDK, which is available for all extant versions of Mac OS X (10.0.x through 11.2.x).
