Unison 2.0.4 MAC OS If you're looking for a clean and yet powerful Usenet newsreader for Mac then you might find Unison an interesting option.
Unison offers everything you'd expect from a quality reader such as threaded discussions, blocking of annoying or nuisance posters, multiple signature management and of course, spell checking. What makes Unison a bit different from your average client however is a four-sided interface that allows you to view and work with Usenet group content in four different ways namely messages, files, images, or music.
You can store files into groups, create favorites, and thread messages. The advanced search can be coupled with rules to better organize files and Unison's download manager lets you handle multiple downloads, reorganize your queue plus pause and launch items based on their priority.
However, there are several instability issues with Unison which still haven't been fixed since the last release. It is prone to random crashes and the image display seems to crash frequently. It also prone to freezing when uploading files. It´s also not particularly clear how you can mark items as read which leads to a lot of confusion when scrolling through posts.
