How do you play after i downloaded a torrent on mac?

It depends on the torrent. After you download the torrent, it should automatically copy it to your applications folder and it should be playable right away, but sometimes you get it as a .zip file, in which case you have to unzip it. It's all fairly straight-forward. If you're still having troubles, the game you downloaded either A: mightn't actually be for Mac; B: the file is screwed up in some way (missing random pieces, or pieces got re-arranged; C: you're new to this and/or you need to get a little more familiar with how computers work.

Ps: pirate bay and utorrent haven't failed me yet, so that's the pair I always use.

Pps: goole the program "wine." you won't regret it.
