Transmission overview

Transmission is a fast, easy, and free multi-platform BitTorrent client.

Transmission sets initial preferences so things "just work", while advanced features like watch directories, bad peer blocking, and the Web interface can be configured with just a few clicks. It supports full encryption, file selection, a Web-based interface, groups, peer exchange, automatic port forwarding, webseeds, watch directories, tracker editing, global and per-torrent speed limits, and more.

Its code is freely available online and is licensed under either the GNU Public License v2 or the MIT License. The development team welcomes anyone who is interested in contributing code, documentation, translations, or other help.

I decided, like Aargl, to take a chance and D/L the latest Nightly Build, #6812 (Jun 24, 2021 4:44:51 AM), and I installed it this morning. Seems fine. I had been having problems with, whenever I had Transmission on, even if there were no Uploads or Downloads, it would slow Safari down to a crawl. That doesn't seem to be happening now... I'm still not getting much of a D/L, if at all... so, something is still wrong. It also has a cool new Icon.

It's weird that as the Developers fix and change stuff for this client, that they don't Upgrade it until they've got a laundry list of upgrades. That's such nonsense... it's like desperately needing to crack all your sunflower seeds before you eat any.

I was a LONG time Transmission user, from when it was really the only game in town. Version 3 is simply too unstable on macOS Mojave and later (IMHO), especially with any more than 3 downloads at a time. TM also would not utilize the full bandwidth pipe of 500 Mbs+ that I have, not even close, 200 Mbs tops. I switched to using qBittorrent on Mac and Windows 3 years ago and haven't looked back. qBittorrent is also free, no adware or spyware (just make sure you get direct from the developer's site.). qBittorrent is extremely stable, uses my full bandwidth pipe and no issues with simultaneous downloads; I can easily have 8 downloads going at once with over a 100 connections, using 450 Mbps of bandwidth.

Does anyone use the "Nightly" Versions from transmissionbt.com? I have some problems with the basic 3.0 Version and Transmission is likely not going to post any updates to it until they get to 4.0.

I have been using Transmission for years and love it. But after I updated to Big Sur it eventually (after a few or several hours) crashes the system (forcing my computer to reboot). Does anyone experience the same?

"Transmission can’t be updated if it’s running from the location it was downloaded to." WTF? What does that even mean?

Love it! Version 3.00 works great for me. It no longer hangs for a while and cranks up my processor when I close it, like v. 2.94 sometimes did. Otherwise, the only difference I can find is Dark Mode, which I appreciate.

I'm having lotsa problems with this most recent release. Half the times I try to Quit it, it Hangs and Beachballs... and after 10 Minutes I'll try to force Quit it, which makes the client disappear, but leaves it Open in the Dock which won't let me Reboot my Computer. So I have to Force a Shutdown. Mojave on a 2010 Mac Pro.

I love this Client. It's simple and works great... and I know it's all done for Free... but it gets updated so infrequently, and then there was the Malware thing... So, anyone know of a good simple Torrent Client?

Ever since this app was hit with malware twice last year, I am very wary of downloading a copy any way other than through the app's autoupdater. But when I use "Check for Update..." in 2.92, it downloads the 2.94 update then tells me "Update Error! An error occurred while extracting the archive. Please try again later." According to https://github.com/transmission/transmission/issues/600 the autoupdater doesn't work on Sierra and High Sierra. What's going on here?

MacUpdate needs a button so "We" can tell them when a Version of some Client is out. You're Two versions behind, guys!
