I don't know about mac, but it's all about the configuration, configuration, configuration. Play with those bells and whistles, you'll see. I've been using Azureus for more than a year, some problems at first (noob), once I got it configured right, flawless, and doesn't slow me down much at all. It only hogs you if you let it. At any given time AZ. only uses 25-30% along with Opsys. I rarely dip into the red, CPU wise, unless if I'm doing something else resource intensive. But, then again I have plenty of power and Ram. Find out your connection speed and config. from there. I've tried bit comet, bit lord, bit tornado, a host of others and like AZ. the best. haven't tried Utorrent though, maybe it's better, I'll have to see. Hope it's of some help. E.
