  1. Kbacks macrumors newbie

    Jul 29, 2012
    I live in the middle of nowhere so I use a Verizon mifi working off of 5 GB of data to connect to the Internet from home. The past few months I have gone over my data limit several times for no apparent reason--I do not watch videos or download anything more than a PDF file or relatively small PPT here or there. I know that my Mac was created to be a social creature, is it possible that the network tasks that it runs in the background such as automatic updates is putting me over my limit? I just upgraded from lion the other day, but as I mentioned this has been an issue for months. Although I use the app store elsewhere, I do not update any of my apps at home.

    Thanks for reading and trying to help!

    Yes, it is possible.

    The utility that you need is LittleSnitch

    This monitors all network traffic in/out of your Mac and allows you to choose what traffic to allow.

    It's not free but is well known and widely used.
