Yes, you did say to use the Property List Editor, my error.
I Property List Editor I added a field under ProgramArguments and entered "-NoMulticastAdvertisements". The com.apple.mDNSResponder.plist permissions currently reads:
user (Me) Read & Write
staff Read only
everyone Read only
Do I add System and wheel to the existing permissions or replace them?
Which permissions are given to System and wheel?
How do I use Terminal to replace the curent com.apple.mDNSResponder.plist file?
Thanks for your time, Roger
You replace them. Easiest is to put that modified plist on the Desktop and use this Terminal command to change the permissions: copy & paste it into the window that pops up, and hit the return key.
sudo chown -R root:whell ~/Desktop/com.apple.mDNSResponder.plist
At the Password: prompt, carefully type in your admin password, since nothing shows up on the screen, and hit the return key again. Once that's done, make another copy of the original plist file, copy & paste in this command which will replace the original one, hit the return key, and restart:
sudo cp ~/Desktop/com.apple.mDNSResponder.plist /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
Ok, I checked /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist and the
was added to the Program Arguments. Unfortunately Console still reports:
4/6/12 1:34:44 PM mDNSResponder Permission denied (NOAUTH): _services._dns-sd._udp.user.members.mac.com. 4/6/12 1:34:44 PM mDNSResponder hndlRecordUpdateReply: Registration of record _services._dns-sd._udp.user.members.mac.com. type 12 failed with error -65537
In doing some housekeeping by going through old files I've found an alias in the Documents > Backed Up Files to my home folder and it's contents complete with a hard drive icon which I trashed siccessfully. Also an iCal Calendars folder in Home > Documents > Archived Items > iCal Calendars folder with Birthday, Holiday .ics calendars etc. It seems like my Home Folder has gotten mangled probably more than once and I'm fighting the prospect of starting fresh, rebuilding a new Mac.
I certainly appreciate your helpful knowledge and time!
