NewsLeecher is a Windows-only program, and does not run on the Mac. So, if you bought a new Mac and now need a Usenet newsreader, take a look at our Super-NZB client.
Or, if you like to browse for files the old-fashioned way, by looking through newsgroups, try ezGroups. If you participate in Usenet discussions, and post files, then NewzToolz is the program for you.
