Mac OS X: restart mDNSResponder
Raw
gistfile1.sh
Load up Terminal (Applications > Utilities > Terminal.app) and type the following.
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
To turn it back on, just do the opposite:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

This worked like a charm.

I've tried sudo killall -INFO mDNSResponder over and over to no avail.

Thanks for the code.

For me sudo killall -HUP mDNSResponder works (http://support.apple.com/kb/ht5343).

/System/Library/LaunchDaemons/com.apple.mDNSResponder.plist: Operation not permitted while System Integrity Protection is engaged

Does not seem to be possible with macOS when SIP is enabled.

@slhck yes, same here, on macOS Mojave.

Takes two reboots, but you can turn off sip, restore dns to sanity and then turn sip back on: Instructions here: https://www.imore.com/how-turn-system-integrity-protection-macos
