Hi,
For current release USB forwarding on MacOSX 10.13.2+ is disabled. It will be officially enabled in an upcoming maintenance release.
For now you can use a workaround that will allow you to use USB forwarding on your machines.
Please open file /Applications/NoMachine.app/Contents/Frameworks/scripts/restricted/nxusb.sh as a root user.
Find here this line
>”$systemVersion” == “10.13.1”
and change it to
“$systemVersion” == 10.13*
NOTE. Be careful, in changed line I remove “” from version number.
Save changes and restart MacOSX machine.
