My iMac (late 2009 with Mavericks) can only start up in safe mode. I have read that it might be related to a mdns responder issue.

The log comes back with 2 kinds of lines which look suspect (but I am totally novice at this!):

May  4 20:39:43 Macs-iMac-3.local racoon[146]: failed to bind to address fd20:c40d:6b6d:9361:80a:aacb:6d80:2d86[500]: because interface address is/was not ready (flags 2)

I would like to try and turn off bonjour by using the Apple instructions http://support.apple.com/kb/HT3789 But I don't know where to put the line <string>-NoMulticastAdvertisements</string> in the mdnsresponder.plist.

Here is my plist. Where should I place this line?

Add it as a program argument. I've added it to the plist below:

  • Thanks. The file says I don't have permission to make modifications. How can I do them ? – user77491 May 5 '14 at 22:30
  • Forget it, I found out, adding myself in the folder and file permissions ! – user77491 May 5 '14 at 22:35
