View Full Version : mDNSResponder

Jan 25, 2013, 03:39 PM
Help! Recently my mac has been firing up its fans at nearly full wack and its every time I plug in my Ethernet cable (via the apply convertor of course)

I go to istat nano and it shows in processess, that mDNSResponder is running at 50% etc. I am pretty convinced this must be the problem. as the cpu temp and fans cool/slow down when i physically remove the ethernet...

help? this is so frustrating

Did you had recently some devices attached which support Bonjour / sharing their name and services.
When of properly detached sometime that daemon runs crazy and try to discover the network. Saw that recently too but played a lots with AFP shares over network.

Tell us a bit more. You can also kill the process (but make sure to have no active files in use)

hi there,

not heard of bonjour before, so cant imagine id have done that?

i tried typing killall etc didnt seem to do anything:/ probably entering it wrong perhaps
