[Solved] New MacOS Catalina breaks DisplayLink

I was able to fix the issue this morning.

Steps that I took:

Uninstalled the displaylink driver.
Shutdown my mac and entered recovery mode.
Opened up the terminal and ran:

Code:

kextcache -i /Volumes/Local

Note: Local is the name of my disk. Yours may vary.
The command returned a string/id/guid (not sure what it entails), but there was no error message.

Code:

reboot

After it booted back up, I opened up terminal again.

Code:

kextcache | grep DisplayLink

The grep returned nothing, which now I knew the driver was gone completely. Grep is a regular expression search, meaning it returning nothing is what we want here as we cleared the cache.

I installed the beta driver and it rebooted.

Afterward, success!
