How To: Fix Final Cut and Bonjour issues

A lot of companies disable Bonjour on Mac OSX for a variety of reasons, usually because it’s very “chatty” and tends to take up a lot of network bandwidth by itself. It can also cause issues with Printer Sharing, causing print jobs to disappear.

But, some Apple products such as Final Cut, and certain Adobe Suite products demand to have Bonjour enabled.

Luckily Apple Support has a perfect fix for this.

1.) First step is to copy the plist file to make a backup, I like to just add .bak to make things easier in the future:
cp /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist.bak (all on one line)

2.) Open mDNSResponder.plist in your text editor of choice. Doing it from terminal is best.

sudo vi “/System/Library/LaunchDaemons/com.apple.mDNSResponder.plist”

3.) Add “-NoMulticastAdvertisements” to the array in the “ProgramArguments” section.

It starts like this:

ProgramArguments

/usr/sbin/mDNSResponder
-launchd

And needs to look like this:
ProgramArguments

/usr/sbin/mDNSResponder
-launchd
-NoMulticastAdvertisements

4.) After saving the file and closing it, you’ll need to reboot the computer. Keep in mind that if you used EMACS to edit the file, you need to remove the temp file it created, “/System/Library/LaunchDaemons/com.apple.mDNSResponder.plist~” first or your computer will not reboot.
