    Hello,

    I have a 20inch imac (bought in summer 2007). I am just getting into using it as my primary computer. I was playing around in order to learn more and I found something through Activity Monitor that does not make sense to me.

    In the Network Activity tab, I see "Data received:" and "Data sent:" sections. As I browse the web, these numbers change of course, but it seems that the Data received quickly reaches hundreds of megabytes! Right now, Data received: is 540MB and Data sent: is 280MB (after a reboot earlier in the day). I am not using the iMac as a server or anything and I have never seen a Windows PC sending out so many packets in the course of browsing the web.


    Is this in line with others' experience? Should I be concerned about a spyware program on my iMac?

    Nothing to be worried about, that sounds pretty typical to me.

    Download the little snitch trial. It will prompt you to allow or deny network connections. Should allow you to see which apps are responsible.

    Do you have Time Machine backing up over ethernet or wi-fi? If so that will count as data being sent.
