Hi.. Im on a limited broadband plan, where each MB counts. Earlier, when I was working on PC, I used some firewalls, which used to notify me and cut out all the connections, which tries to connect to the internet. Now, on iMac, I have got a huge bill of 2500$ for this month and just installed iStat Pro . Now, when i switched on the iMac and checked on iStat Pro for live reading , it runs like hell. Im doing nothing, and its 300mb in 2 hours. My apps running are ADIUM, SKYPE, MAIL, FIREFOX (no live browsing going on, just localhost MAMP). I dont know, wtf is using this data. All I know is, I have to pay this 2500$ now for this stupid thing, which I cant even track. I have installed Little Snitcher , but no good. F**k.
