Unison is a solid Usenet newsreader available for Mac OS X 10.5 and later. It is designed for downloading binaries and reading Usenet newsgroups. The final version of this newsreader, 2.2, was released in November of 2014.


Unison is free to download and use.

While Unison can search downloaded message headers, there is no online search included that will scour all of the newsgroups as seen in Newsbin, Grabit and Newsleecher. That said, you can use the Search Browser to find files and NZBs

NZB Support

Unison supports NZB file downloads. There is no auto NZB import feature but, with a little tweaking, you can create an auto import NZB folder by following the instructions here

Platform Information

Unison works on Mac OS X 10.5 or later.


Unison is an excellent Usenet Newsreader. Especially if you are a Mac user.

More Details

As of version 2.2, released in November of 2014, Unison is free and completely unlocked for all users. Version 2.2 will be the last update for this newsreader.

The final update added multi-connection downloads and Retina assets to the program. It also fixed some outstanding bugs.

Unison allows you to read messages using a thread view, which makes it much easier to browse through all the content. Thread lines make it easier to see who replied to any given message. You can post and view messages in HTML or plain text.

Unison also conveniently groups files by type when you’re downloading.

  • Built-in UnPAR/UnRAR/Join, no external tools needed
  • Set up rules to manage your messages
