i recently bought the new macbook white and i had the same problem... however i have very good experience with uTorrent, it downloads music, films, programs, everything, and there are lots of websites with files saved as torrents. it is very small, fast and reliable, however for mac you need to get bit Torrent for macs, but there's not a big difference, it's practically the same.
Torrent it's really great
