Displaylink not working after upgrade Catalina 10.15.4

Hi,

PilotPete, to upgrade the firmware you have to have Windows computer. As the files provided by the manufacturer can only be used with that operating system.
The file is available at: https://www.dell.com/support/home/uk...-d6000/drivers

1. When you do the update make sure you do not have anything plugged in to the dock.
2. Connect the dock to machine running Windows and run the file downloaded from the website.
3. Follow the wizard and once this has completed you can connect your dock to your Mac.

Also double-check if you have Supplemental Update for your macOS available, if yes then please make sure to apply it.

Best regards,
Katarzyna
