Prior to updating to Catalina, I had successfully disabled Bonjour advertising on my server by using the following command in the terminal:
defaults write /Library/Preferences/com.apple.mDNSResponder.plist NoMulticastAdvertisements -bool YES
However this no longer works in Catalina. I run the command, using sudo, but the computer continues to advertise itself on Bonjour. How do I disable this in Catalina?
Before moving any service plist file, it is necessity to discharge the service before changing of anything.
To unload the mDNSResponder service issue:
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
Insert into "NoMulticastAdvertisements" for configuration:
sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist ProgramArguments -array-add "-NoMulticastAdvertisements"
Reload service without Bonjour Advertisement:
sudo launchctl load /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
Check Text ( C-75751r1_chk )
How to check the multi tasker Bonjour advertising has been disabled, you have to run the following command;
/usr/bin/sudo /usr/bin/defaults read /Library/Preferences/com.apple.mDNSResponder | /usr/bin/grep NoMulticastAdvertisements
If you finds any error in the returned or nothing would be returned, moreover “NoMulticastAdvertisements” is not set on the ‘1’, that’s the finding.

NB Unloading mDNSResponder requires disabling system integrity protection. Otherwise I think this worked. Thank you!
How do you disable Bonjour advertising?
