Acetaldehyde

Okay, this may be completely obvious. But some input would be helpful. I made an account, tried to download the Mac Torrent but I got: "Safari can’t open the file “WoW-1.12.1-enUS-Mac.torrent” because no available application can open it." I just started downloading WoW from Battle.net, It still currently has about 35g left to download. Do I have to wait for the entire download to properly use the torrent? This seems pretty obvious after typing it, but I'm still curious. Thanks for your time.

Figured out I need to download a torrent client, LOL.
