Universal Media Server is a free and open-source DLNA compliant UPnP media server.
Originally, this tool supported the PlayStation 3, but has now been expanded to support a range of other media renderers, including Xbox 360 and various Samsung and Sony televisions.
Universal Media Server streams or transcodes many different media formats with minimum configuration from many platforms. It is supported by the MPlayer and FFmpeg package.
Step by step instructions on how to install and use the Universal Media Server utility on your Mac are available in its Help menu.
Universal Media Server is cross-platform and it works on macOS, Windows and Linux. Binaries for the Windows and Linux platforms are available on the project's homepage.
Furthermore, in order to use Universal Media Server on OSX10.8 or later, you will have to either temporarily bypass or completely disable Gatekeeper.
Detailed instructions on how to do that are available on Universal Media Server's wiki.
