If you don't want to buy any fancy GUI software, you can try nettop in Terminal.app

Use the arrow keys or w or s keys for scrolling. Use -n option to disable IP address reverse resolution.

Example of an output:

Pretty awesome right? Best of all, nettop is embedded in OSX (well at least in Mountain Lion).

Solution 2

Rubbernet looks good.

Rubbernet provides a breakdown of per-app network usage, so you can quickly detect apps that phone home, connect to certain servers without your knowledge, or blame the app that's slowing down your network.

Solution 3

Try LittleSnitch:

A firewall protects your computer against unwanted guests from the Internet. But who protects your private data from being sent out? Little Snitch does!

Solution 4

In OSX 10.9 simply use the built in Activity Monitor:

Solution 5

Rubbernet is something that does everything you ask for. HOWEVER be warned. It is expensive, and it does not come with the features you'd expect for in basic freeware, let alone an expensive piece of software for monitoring usage. Limitations include:

loses all measured data when laptop sleeps
loses all measured data when VPN status changes
no "total measure" on the summary page: only the individual amounts used per app

Can anyone introduce me a Mac OS X application that monitors all network activity such as what applications are now connected to the internet and how much bandwidth they use (I mean show bandwidth separately for each application)?

Am1rr3zA over 14 years

I have LittleSnitch but it just show what application use internet don't show BW for each application
rogerdpack over 12 years

it does show which apps are currently using bandwidth which at times is enough...
Mark Beaton about 12 years

This app is exactly what the OP is asking for. It works.

Furthermore, the support is non-existent. No documentation, no response to tickets...

Incidentally, it's "outbound firewall" feature just showed me that I am running an app that is phoning home rather unexpectedly!
HikeMike over 11 years

The description doesn't look like these show individual applications' bandwidth. Can you confirm this feature exists, maybe post a screenshot?
Simon over 11 years

@Daniel Beck - In the Noobproof description it states you can tune the bandwidth manage black lists and create self-configuration tools called injectors.
HikeMike over 11 years

I only found "Limiting bandwidth" which is different from "showing actually used bandwidth", which is what the OP asks for. Could you please be more specific?
Simon over 11 years

@Daniel Beck - In the 1st paragraph 7th line down it states you can tune the bandwidth
Tom Panning over 11 years

This is perfect, and if you press the <kbd>d</kbd> key, you can toggle between cumulative totals and the "diff" mode (how much each app used in the last second).

nethogs on ubuntu is my best friend... I am searching similar for mac.

Tuning here means you can set how much network bandwidth can be used by a process I think. That has nothing to do with showing how much a process naturally uses, for instance to see if a certain application is very active when not be explicitly used, or to search for a rootkit/virus/malware.
Johnny Utahh over 9 years

Is there any way nettop can real-time sort such that processes using the most (current snapshot instead of historical) bandwidth are listed first?

You can click on the application in the window and it shows the graph of the network usage per application.
Gray about 8 years

Unfortunately I can't get it to show recent network bandwidth usage per application. Were you able to?
