Tomato Torrent is a BitTorrent client for computers running Apple Computer's Mac OS X operating system. Tomato Torrent is currently built on the 4.2 branch of the original BitTorrent client, with the program structured to separate the BitTorrent code from the Macintosh code. The program currently requires Mac OS X 10.4 or higher, but previous beta versions are available for Mac OS X 10.2 and 10.3.
