I would like to be able to summarize daily network bandwidth usage for running applications. Additional details, such as a sorted list of addresses by traffic usage, would be nice to have as well but not essential. For the most part I just want to know which apps are using the most bandwidth.

All of the solutions seem far too detailed or complicated. These include:

  1. Terminal applications like nettop
  2. Commercial applications like LittleSnitch

The closest I've come is use nettop and export its results to CSV. I'm hoping there is something much simpler.

  • Just noticed the "software-recommendation" tag. FYI, there is a software recommendation Stack Exchange site for this kind of stuff too: softwarerecs.stackexchange.com

  • Does this answer your question? Bandwidth shaper or bandwidth controller application for Mac OS X

Use Activity Monitor

Just open Activity Monitor (Applications -> Utilities -> Activity Monitor) and navigate to the Network tab. You'll be able to see which apps are sending/receiving data and how much per app/process.

  • I'm familiar with Activity Monitor. TripMode is much simpler and will block apps as well.

This is closest thing I can find. For $8 it's a no-brainer.


There are some other options:

  1. Activity Monitor. Too granular and only calculates when it is open. Does have the advantage that individual Safari tabs appear separately and it is very easy to kill a process.
  2. Peak Hour. Doesn't appear to track specific apps, but it looks like it talks to the router. It might be good for broad network evaluation of traffic usage.
  3. BitMeter. Tracks aggregate bandwidth use. Includes a nice web UI but no per-app info. Open source. I used this to find which app was using up loads of bandwidth by turning the suspects on and off and watching per minute bandwidth use.
