How to Monitor Network Connections on Your Mac

Do you use a monitor for your Mac network connections? Even though some people may feel that it’s not important, a network monitor can really come in handy – especially a free one like Private Eye.

With Private Eye, you can see all of the connections to your network in real-time – both incoming and outgoing connections. You can’t use it to block connections from specific applications. However, the makers of Private Eye have the Radio Silence Mac app that you can buy for that purpose; it serves as a firewall and can block any application from accessing the Internet.

For now, let’s take a look at how to monitor Mac network connections and see if any unauthorized applications are accessing your network.

1. You can download Private Eye for free from their website. The app requires you to have Mac OS X Lion or Mountain Lion.

2. Once you run the installer, you’ll need to open Private Eye from your Applications folder or Spotlight.

3. Private Eye is extremely easy to use, if not a little time-consuming. It may take a few minutes for all of your applications and connections to show up, so you’ll have to be patient.

4. All of your connected applications are displayed in the lefthand sidebar. Clicking on an application will filter out the others and only display connections from that one application.

5. You can also filter outgoing and incoming connections by clicking on “Outgoing” or “Incoming” in the lefthand sidebar.

Unfortunately, there’s not much else that you can do with Private Eye. You can’t close out or block connections; there aren’t even any preferences for the app. It’s strictly just for monitoring your Mac network connections, yet does that very well.
