All was working great.

Upgraded to Catalina 10.15.4 - Now only two of the monitors will work and my printer that was connected via USB to the D6000 does not work.

I have tried both the BETA and the Kernel drivers with no luck.

The BETA does not launch an application. Just runs DisplayLinkManager and DisplayLinkUserAgent in the background.

Let me know what you want me to try next.

Hello,

Thank you for describing your issue.

Did you try upgrading the firmware in your D6000 dock? As it proved to be a solution for users that faced the issue on this specific docking station.

Unfortunately this update can only be done on the windows computer. If you are able, please perform the update by downloading it from here: https://www.dell.com/support/home/uk...k-d6000&lwp=rt

After updating your Firmware, please plug it again to your Mac computers and verify.

Thank you for checking that.

Best regards,
Jakub
