Also I Install ChmodBPF

If there's no /Library/LaunchDaemons/org.wireshark.ChmodBPF.plist file, it wasn't correctly installed.

I suggest that you download the latest version of Wireshark, drag-install it in Applications, and then double-click the "Install ChmodBPF.pkg" package and run all the way through the installation process.

ls -l /Library/LaunchDaemons/org.wireshark.ChmodBPF.plist

still says

ls: /Library/LaunchDaemons/org.wireshark.ChmodBPF.plist: No such file or directory

after running the "Install ChmodBPF.pkg" installer package again?
