What is described in the official upload guide (https://www.gaytor.rent/uploadguide.php) and the alternative upload guide (https://community.gaytor.rent/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).

@hhsq: I am having this problem too… I have seeded a lot of files for days and my ratio doesn't seem to improve. I didn't download many files recently... It's just as if the share ratio had frozen. The files you are seeding have ZERO leechers that is why.  Check your torrent page for the # of seeders and leechers.

Running it as ADMINISTRATOR does the trick
