Transmission is another great choice for torrent downloading. This torrent client is free to download and native to Mac. It has a really cool web server feature that will let you access Transmission when you are at a remote location.
Vuze is also easily one of the best torrent clients for Mac and is also extremely popular across several platforms. Vuze is rich with features and has a ton of configuration options that uTorrent doesn’t offer.
A really great option among Mac OS X torrent clients. It is pretty fast and offers the same functionality as uTorrent. It supports tasks prioritization, remote access and control, a built-in media player, etc.
This is of course one of the most popular Bittorrent downloaders across multiple platforms. Unfortunately a lot of reports surfaced warning that uTorrent is becoming unsafe with more recent updates.
