Transmission is a fast, easy, and free multi-platform BitTorrent client.Transmission sets initial preferences so things “Just Work”, while advanced features like watch directories, bad peer blocking, and the web interface can be configured with just a few clicks.
Macworld put it this way: “It’s fast, it’s extremely lightweight, and even though it’s available for a variety of platforms it behaves just as you’d expect a Mac program to.”Transmission supports full encryption, file selection, a web-based interface, groups, peer exchange, automatic port forwarding, webseeds, watch directories, tracker editing, global and per-torrent speed limits, and more.
OS: Mac OS X 10.5 or later.
