I wasn’t very clear on this in the article, but you need to restart your Mac after changing the permissions for the script to work. Adding an update to my post to make sure nobody misses it in the future. I just reinstalled on Mac OS 10.6.4 and everything shows up fine for me after a restart.

Same as Thomas, still not having any luck. I opened up the command prompt copied the above command
cd /Library/StartupItems
sudo chown -R root:wheel ChmodBPF

It asked me for my password, i entered it, pressed enter then opened up WireShark.
Still no interfaces or capturing devices

Thank you so much. This was driving me crazy only being able to get it to work from the command line.

Also, for the StartupParameters.plist files, invoke this from the CLI:

sudo chown -R root:wheel StartupParameters.plist

then restart so that BPF permissions are enabled for Wireshark, or simply
invoke this on the CLI without restarting:

sudo SystemStarter start ChmodBPF

The above commands did not work for me, but this did:

sudo chmod 644 /dev/bpf*
