Nice little app! It seems to work fine under Mavericks (10.9.3). I use this when determining whether a system requires an outgoing firewall app like TCPBlock or Little Snitch.

It's no match for the slick interface and data monitoring power of Little Snitch's network monitor, but I don't expect it to be for free. The other side of the coin in this comparison is that Private Eye has a lighter resource footprint and is easily removed from a system.

I just installed on OS X 10.7.3 and I guess it's working - can't tell, it's just a blank window. However, I can't monitor any apps or see a single connection.

Maybe, as ronoho said, it's because I'm connected via a USB antenna.

PE stopped working so I deleted the app and the prefs, re-installed it and working again under Lion 7.3.

This would be a useful utility, but I had no chance to get it running with LION (10.7.2). The hint (FAQ) to install it once again could not help.

Looks nice, but does not work with Wireless connections. Unable to set preferences, unable to select network adapter.
Filtering of output would be very nice for a future release.

Seems like it's been updated. It's getting wireless connections for me, and it does offer filtering of various sorts.
