(Two known issues, the secondary mDNSResponder will not receive unicast mDNS packets and it does not support BTMM.)\ \ 1.) From Terminal shell, open mDNSResponder Xcode project. \'a0\ \ $ open mDNSMacOSX/mDNSResponder.xcodeproj/\ \ You can also just double click on the project from Finder.\ \ 2.) Configure Xcode Project Scheme by adding the following three arguments, -d -NoSandbox -UseDebugSocket.\ \ \pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardeftab720\pardirnatural\partightenfactor0 \cf0 \kerning1\expnd0\expndtw0 {{\NeXTGraphic A944EB40-AEFD-4CA1-BF10-E8F52835CA8C.png \width18360 \height4420 }¬}\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardeftab720\pardirnatural\partightenfactor0 \cf0 \expnd0\expndtw0\kerning0 \ \pard\pardeftab720\partightenfactor0 \cf0 \ 3.)
