When looking at my OSX firewall settings, I see that the application is set to accept incoming network connections.

How come that's set to true by default?

IIRC, it's not set to true by default. You must have allowed it at some point. – slhck Jul 9 '12 at 21:29
Not enabled for me either. – Daniel Beck Jul 9 '12 at 21:30
Maybe. I hope to remember if I did something like allow the Finder to accept connections, though. Disabled. – blueberryfields Jul 9 '12 at 21:32
