Download of Mutella 0.4 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application is included in Internet & Network Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
Mutella is a terminal-mode Gnutella client with an intuitive and easy to use interface. Initially written by Max for himself, Mutella has now been released to the general public for the benefit of all of us in need of a solid, high-performance client. Mutella supports all the functionality required to participate as a full-featured node in the Gnutella network. "Full-featured" implies support for file search, download and sharing.
