Hello, I am in need of a program that would be able to track what applications on my Mac are using the most data. I currently have a limit of 250GB's and have been maxing it out lately and I can not figure out how or why. I don't stream or download movies if that is your first question. I mainly use it to run my home real estate business. I restarted my Mac yesterday and opened up Activity Monitor so I could check out the data received. I have not used the computer at all but by this morning it had received 12.77GB's of data and I have no clue why. Is there an easy way to find this out? Would prefer a free or relatively cheap program to help me understand. I tried a search on here and couldn't find what I was looking for (maybe search wrong words). I also did a Google search, but only found stuff talking about monitoring total bandwidth used and not app specific. I appreciate the help!
