Transmission free download for Mac


24 May 2020

Popular BitTorrent client.


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.

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?
