I use Acquisition. It's a Gnutella-based peer-to-peer and BitTorrent client for Mac OS X. It's based on LimeWire. I guess it would be equivalent to Limewire Pro since there's no real danger in file sharing for Mac users, other than getting caught by the government or RIAA for file sharing. Which is a danger we all share regardless of the type of program or OS we use.
