Unfortunately Microsoft can't perform an update without crippling entire machines. Just do a Google for "Windows 10 Creators or Fall Update won't boot" and you'll see a host of unhappy users rebuilding their machines or performing PC voodoo to resurrect their computer.

However I agree it is a great pity that Apple steamrollers architectural changes without working more with 3rd parties.

displaylink.com also down?
 

I came here with the same issue. But it sounds like there is a beta version of the driver that may work? Unfortunately displaylink.com seems to be down at the moment.

Don't expect Apple put anything in there release notes about it being fixed.

Not even going to attempt to try it on my now home Mac to even find out. I don;t trust Apple and whatever else they may have packaged in here that will result in me loosing hours. I'll wait to see someone else offer up whats broken in forums.

Apple update did not work for me
 

Steps I tried:

1. Downloaded update
2. Confirmed did not work with restart (still showing cloned desktop)
3. Uninstalled DisplayLink beta driver
4. Restarted
5. Confirmed did not work (black screen)
6. Installed current latest release of display link driver
7. Restarted
8. Confirmed did not work (black screen)

Hello,

I can confirm that:

- After removing the beta drivers and reboot
- Download Apple Security update 2018-001
- Install DisplayLink 4.1 Drivers (not beta ones)
- Reboot

Thats was working for me.

Dear DisplayLink macOS users,

As we previously advised, we are aware that installing macOS version 10.13.4 will cause DisplayLink connected displays to go blank after the OS update, with the latest DisplayLink driver release 4.1 installed.

Extended displays continue to work as expected in macOS 10.13.3 - this is why we recommend remaining on macOS 10.13.3 or earlier at this time. Functionality such as Ethernet and audio, where implemented, is unaffected on macOS update.

DisplayLink has committed significant resources to finding a way to restore extended mode display support in a future release of macOS.
We have made solid progress towards identifying a solution, however our team needs to complete more work before we can communicate a release plan for a driver that will restore extended mode displays.

In the meantime, DisplayLink driver 4.3 Beta 2 enables clone mode, but not extended mode, displays in 10.13.4. Users who have already updated to 10.13.4 should install that driver.

We will update you on this thread as soon as we have further details to share.
Thank you for your continued patience and we appreciate your feedback and support.

Kind regards,
Alban

This did not work for me...
