Somebody please help and I will seriously send you cookies or a donation. I have a new mac mini (purchased around janaury, 2013) - it is running 10.7.5 Earlier today I was fiddling with Terminal trying to do a few things like clearing the DNS cache/flush, sudo killall -HUP mDNSResponder (which didn't seem to work) then I tried to unload then load the /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist -- anyways I believe I have disabled my DNS because my WIFI symbol at the top is connected but when I open the web browser I get nothing and my other computers and devices work fine. I think I have to re-enable the DNS but canno't find a solution ANYWHERE on the dang internet. Everything I try in Terminal will give me permission denied and I really don't have any idea what I'm doing. ANY help would be greatly appreciated. I don't know how to go about resolving this Mike.
