As a Mac user your choices are somewhat limited when it comes to Usenet client. Not to be concerned though as some of the largest Usenet providers like Newshosting have Mac software. I use it on my iMac and it works great. You can also go the web router and use Easynews. Either way you’ll have great service. If you already have a Usenet provider then I’d also recommend looking at SABnzbd, Unison, and NZBVortex.
Best Usenet Clients for Mac
We’ll start with Newshosting since they include the Mac client with the service. Those who sign up for their annual special also receive free VPN access. You can enjoy unlimited Usenet with a nice client and VPN from just $8.33 a month. The Newshosting software will help you find content. You can even schedule searches to ensure timely downloads. The Mac client is very similar to their Windows version which is also good.
Easynews is all about convenience. I recommend the service for those who want the benefits of Usenet without installing any software. They have the only full featured web interface. You simply log into their site and use the web interface. From there you can search for content, preview, and download directly from your web browser. This is a great option for those new to Usenet. Their service starts at $9.98 a month.
SABnzbd hardly needs an introduction. The web-based client has been downloaded millions of times. It is free and open source. Given it’s popularity, many popular search sites have integrated with SABnzbd. The client is a solid choice for those who are a bit more tech savvy. It takes some work to get it configured to work with popular sites like Sickbeard and CouchPotato but once you do it’s a great set up. I recommend looking at the SABnzbd forums for help.
The Panic team discontinued development of Unison in late 2014. That’s a shame since the newsreader was a great choice for Mac users. As a farewell gift they made one final version and are offering it free of charge. There will not be any future updates though. For that reason I would suggest going with a different client. NZBVortex is another good option. While it isn’t free they do offer a stripped down version for testing.
