This is a part of the instructions: "Add this to a resetPa.sh : #!/bin/bash rm -rfd ~/library/preferences/com.pa* rm -rfd ~/library/preferences/pa/* rm -rfd ~/library/preferences/pa I searched in spotlight and I don't seem to have a file called resetPa.sh Do I need to create it? How? And how do I continue from here? Thanks for your help!
