What is described in the official upload guide (https://www.gaytorrent.ru/uploadguide.php) and the alternative upload guide (https://forum.gaytorrent.ru/index.php?topic=18666.0) is valid for Mac (OSX) and GNU/Linux, too.
The pictures for illustration were taken on a Windows OS computer, but they could have been taken on a Mac equally and would even look very similar if µTorrent for Mac were used. The description fits as well Vuze, Transmission, qBittorrent or Download Helper (just to name some I know).
