limewire
Well. Since we dont have any options like Kazaa as mac users I have found limewire to be an adequate replacement. It still isnt kazaa but it does do a good job of finding songs, programs and videos. At first I hated limewire but eventually I got the Limewire pro version without the banners, and now it seems much faster and responsive. Although I have not experienced any downloading problems with limewire it can be hard to find somthing particular at times. What I do is leave limewire on whenever my computer is on. I keep 5 server connections active at a time, and over time limewire accumulates more and more hosts, therfore making more content available. It dosent work good if you just boot it up and search right away, give it time to accumulate a good amount of hosts then try a search. Also try the pro version, it is much better.
