Application for monitoring all applications that are using the internet in Mac OS X
I've recently received MacBook Air with OSX 10.8 (Mountain Lion) and i'm not so into the details of the system yet. I've recently bought a modem which works very well, but the problem is that the modems ISP prices for internet are really high and due to lack of competitor ISPs which have good connection and speed in the location i'll be using it, I have no other choice.
So i would like to lower the "internet usage" of mac to minimum (Only to things that i'm using and are required for minimum functionality). In other words i would like to turn off any background services or processes that use internet (Update services and likes).
