Dear All,

I am using MacPro 5.1. When I use it on Mojave, its all working. But when I connect a disk with High Sierra, then there is no display on the screen connected through USB Display Link. Even it doesn't show in the display.
I have done some troubleshooting as follows:

1) DisplayLinkDriver Extension and Kext version 4.3(206) is Enabled and loaded.(About this mac -->System Report-->Extensions-->DisplayLinkDriver)
2) There is noting in Security & Privacy (General tab) to allow - perhaps its already allowed.
3) Uninstalled and rebooted and then installed the driver for High Sierra several times -While the displayLink display/hub was not connected but nothing.
4) Didn't find any information on the forums for this.

Kindly help.

Regards,
