Here there using the following
Mac latest Catalina
WD Duo latest firmware
WD Discovery latest
I can see my duo on finder and via discovery BUT
None of the utilities work saying they can’t see the drive (but see above discovery can).
I can’t manage or test the NAS drive with the WD Disk Utility or WD Security.
I don’t need WD Sync as using ChronoSYnc express which is excellent
Clearly I need Drive utils and Security working
