I'm new to Mac. Just got the 27" i5. First, my Interent gets really slow. Tests show a latency of ~3000ms. When I restart the Mac, it gets better for a while, but goes down again. Very difficult to use the Mac this way. Second, I can't connect to anything in Colloquy. I've tried a number of servers. No error and nothing in the console. I would really appreciate any ideas.
