It’s a MacBook Pro running macOS 10.14.6.  I just upgraded Wireshark3 by rebuilding it using MacPorts.  Previously, just manually entering the “sudo chgrp…” and “sudo chmod…” Unix commands used to work fine.  Now it’s not.

Hi,

It would probably help if you listed what your system is and what you were doing before.

Thanks,

Jaap

Does anybody know how to fix the above?
