Hi ! .. I am using MacBook Pro Leopard 10.5
Well i can download from links and web sites but my problem starts when i try to download using program like torrents and Steam or Battlenet Blizzard
can i know whats the reason for that ?
i have switched off all the firewall and checked for the settings related to the programs and even in mac setting but i cant find an answer 2 it .... i have this problem from the time i bought my macbook pro 1 year ago .

Sorry - I don't know anything about Stream and Battlenet Blizzard...
About Torrents, can you please give us a web site to check out the problem - and, can you tell us which Torrent client you use.

actually i tried to use different types of torrents .. like Utorrent bitcommet bittorent etc non of them work and i download from http://thepiratebay.org//

OK, that's good info so far.
What you didn't tell us is a specific file you were trying to download.
This matters, because even though lots of files are "available," that doesn't mean there will be "seeders" to provide every file at a given time.
I have gotten frustrated and given up many times because it looked like I would be waiting several days for the download to complete.
Is it possible this is your situation?
