Default 2017 MBP 15": Updated from 10.13.3 to 10.14.2, confirmed working w/o DL Driver update

Hi all, hoping to help with my recent finding. After running 10.13.3 for quite some time, I decided to run a backup and pull the trigger on the 10.14.2 update.

I did not update manually DisplayLink drivers after updating from 10.13.3 to 10.14.2, and am running 10.14.2 with 3 fully-functional monitors as extended desktops off of a StarTech USB-C docking hub, with none mirrored or requiring the AirPlay workaround. It appears to be using the same DisplayLink Drivers and configuration I had installed and ran on 10.13.3. I haven't noticed any issues with output or graphics performance, so I wanted to report this for those running this machine.


1. While running latest 10.13.3 (w/ all combo/security updates for 10.13.3) + DisplayLink 4.1 Driver, run Time Machine backup.
2. Once backup is complete, go to the App Store to download, run Mojave 10.14.2 update.
3. After the update is complete, DO NOT change/modify/install any DisplayLink Drivers; rather, reboot a few times to test functionality.
--- If extended desktop doesn't work after rebooting a few times, try updating to the DL 5.0.1 Driver.
4. Report back to this thread with your results.
5 [Hopefully] PROFIT!

MacBook Pro 15" 2017
2.8Ghz Core i9 w/ Radeon Pro 555

Prior configuration:
OS X High Sierra 10.13.3
DisplayLink USB Driver 4.1

Current configuration:
OS X Mojave 10.14.2
DisplayLink USB Driver 4.1**

**AGAIN: I did not manually run the update to DisplayLink Driver 5.0.1 - So unless it somehow ran the 5.0.1 update on its own automatically, I am still running the same DisplayLink USB Driver 4.1 I had used while running 10.13.3

If anyone needs a copy of the 10.13.3 update, please PM me and I will do what I can to share that file with you.
