Unison is a macOS client for Usenet. It supports binary file downloading (including NZB support), group browsing and segmenting, and error-checking utilities.
In this tutorial we walk through installing and configuring Unison to work with our secure Usenet servers on your Mac.
Visit the official Unison website to download the installation file. Place the Unison application in your Mac HD Applications folder, then launch it. Once Unison opens, click "I have a Usenet server already".
On the "Servers" screen, configure Unison with Fast Usenet: server news.fastusenet.org, secure (SSL) connections on port 563, plus your Fast Usenet username and password.
A categorized directory of newsgroups appears. If you're just getting started with Usenet, the categories help you locate a group you might be interested in.
Back on the main Unison screen you'll see "Directory" and "All Groups" in the left menu. Select "All Groups" to view a list of all available newsgroups.
Filter the groups by keyword. For example, searching "Linux" shows only matching groups. Double-click a newsgroup to subscribe.
Subscribed newsgroups appear in the left menu. Click a group to select it, and Unison connects to our servers to download the latest articles.
The downloaded articles appear in the right menu. You can now view and post to the newsgroup. To post, contact support to request posting privileges.
