Open transport was a technology used in Mac OS 9 days. I haven't use MT-NewsWatcher for years. I guess it was written as a Carbon based App when transiting from OS 9 to OS 10.X days and from what I know it stopped working in Mac OS 10.7 (Lion) since Rosetta was no longer supported. MT NewWatcher hasn't been updated in years. I think you'll be out of luck unless you can find a different app. Good Luck
The fact that this issue is not being discussed much at all in many of the venues and usenet groups dealing with Apple and OSX, shows just how little traction the problem is getting.
I'm convinced this won't be fixed in Mavericks, and for MT-Newswatcher there is little hope since the developer hasn't updated it in a very long time. In fact, I think it is abandoned.
Unfortunately for me, I haven't found any other usenet client for OSX that I really like. I can and will use Thunderbird, but I'm not gonna like it!
While there is no free replacement for MT-Newswatcher, it appears that Thoth works fine in Mavericks. I got the trial today and am contemplating getting the paid versions ($25 via paypal).
Unfortunately for me and my lack of patience, I had already got and paid for Unison.
That's not a knock on Unison BTW, it is a fine program and I very well may not change over to Thoth as I get used to Unison's way of doing things.
Thoth is excellent for downloading rar's, not so good for viewing images inline. In fact, I still haven't found a good way to use Thoth to view images inline. MT-News on the other hand was a snap, click on the file and bang! it opens up with no overhead or other crap on the screen to deal with. No hassles with 'thumbnails', cataloging or other bloatware.
MT-News was perfect for viewing binaries. Its only weakness was the 100,000 limit. Thoth (my setup anyway) has a 1,000,000 limit, much more useful.
Now. How to go about dumping Mav on my 2011 Mini and reloading MT Lion. Besides, I hate those stupid little 'tag' things that some nimrod put in there instead of labels. The same guy would probably mount a gas tank on the front bumper just to stand out in the design meeting.
That application is SO OLD! Those are purely legacy APIs.
Panic's Unison is my newsreader of choice, though I'm not keen to PAY for newsgroup access and most of the free servers have shut down. Panic does host a news reader service, I'm sure it works well.
Even if it's not the main purpose of this topic, i add that the fact of removing Open Transport from Mavericks has some effects on others soft too :
For Warcraft 3 TFT (topic here) for exemple, internet connexion is impossible since Mavericks upgrade.
Can apple developpers find any kind of solution for that kind of softs that still use this kind of connexion ?
Any patch ? Any app ? Or is there a technical incompatibility ?
I know there are many gamers in the case of War3 who are ready to go back to Leopard or Lion just to resolve this problem..
(sorry for my english - thx)
Only you can decide that, of course.
I got the newest version of Thoth just the other day to try, also got Unison. My problem now is that I like both of them for different reasons. So I bought both!
If you really liked MTNW, then moving to Thoth is the simplest move you can make as most everything about it is very similar in operation. Setting it up is a little more convoluted than MTNW, but not that daunting.
Unison is more OSXified and is a nice multi-pane program. It is quite powerful and works very well.
Frankly for text, both are great. For binary pictures I think that Unison might be a bit better, but I don't do binary usenet.
BTW, both have free trials. 30 days for Thoth from the developer, and a week (I think) for Unison. Get the free trials by doing a Google search.
Hope this helps.
So much for Thoth.
Purchasing a Thoth Registration
My apologies for any inconvenience, but it is no longer possible to purchase a Thoth registration.
