Starcraft Mac files

Hey,

I'm looking for a torrent for a legit sc2 Mac installation. I'm trying to see if I can run sc2 on the school computers but I don't have the 8 hours needed on it to download and install the files.

Basically I'm looking for files that I could just burn to a flash drive and run off of. Is this possible? I wouldn't need campaign or anything, just bnet.

Thanks
