When it comes to peer to peer (P2P) downloading, the best applications on Mac are still aMule and Limewire. Yet users looking for a friendlier alternative can turn to XFactor, a P2P application giving you access to most of the major networks like Kazaa, Gnutella and Ares.The program's interface, very similar to that of iTunes, shows all your downloads in progress in the central part. Searches made in the box in the top left of the window are then shown in a list in the left of the interface.
The app cleverly integrates your iTunes library, accessible from the menu in the bottom left of the interface, making it easy to share all your music with other users.
The integrated player is also quite useful to preview videos being downloaded.However, since this review, XFactor has been discontinued and the developer page is not even available anymore, so we fear this is the last incarnation of the program you'll find.
