solve this
after update Xcode8 and macOS. macOS file System is change UE 13.4.1 resource file name. so i changed file name in log file.
LPVDirectionalOcclusion.usf to LpvDirectionalOcclusion.usf (Change ‘PV’ to ‘pv’) DEbugviewModeVertexShader.usf to DebugviewModeVertexShader.usf (Change ‘DE’ to ‘De’);
after the change file name, it works properly.
if you don’t know what to change filename, see "~/Library/Logs/Unreal\ Engine/Editor/UE4.log ". you can know what to change file name.
