Some users have experienced a problem with USB devices forwarding not working when connected using an Active Directory account on a macOS machine.

In order to be able to run NoMachine USB Service on macOS, the current user should be a member of the “staff” group, but AD users usually are not members of such group by default and the user needs to be added manually.

To check if the user belongs to the “staff” group, launch the Terminal app on your mac machine and execute:

dscl . -read /groups/staff | grep GroupMembership

If the user is not in the staff group, add it by running:

sudo dscl . -append /groups/staff GroupMembership <ADusername>

Note that the last command should be executed with sudo permissions.
