eMule isn't available for Mac yet but there are other alternatives which runs on newer Mac operating systems with similar functionality. Other interesting Mac alternative to eMule would be Bit torrent (FSF), also referred as BTF. Other cool Mac alternatives to eMule would be MySpace, Giganews, Facebook, Foursquare, Twitter, Technorati, Urchin, FourSquare, Tagged, YouTube and Vimeo.
One of the main problems with eMule, that's why it's not available to those mac operating systems which are not compatible with the protocol, is its lack of a proxy server. A proxy server is responsible for transferring data between two web sites. Because of the absence of this server, the download speed would be greatly reduced and would depend on the speed of your internet connection. If your internet connection is pretty slow, you might not be able to download anything at all.
With some research on the net you will be able to find a reliable site where you can download this product. It is important to know that eMule works through the use of P2P technology (peer-to-peer technology). Meaning you can download music and movies using an amule client and transfer it from one computer to another. The technology is similar to that of Napster and is considered to be legal because it only involves downloading and not sharing. I hope this article helped you in deciding whether eMule for Mac is for you or not.
