Displaylink ceases to work in 10.13.4

Sofla David · 08-10-2018, 01:48 AM

Unfortunately, I'ver rebooted, Uninstalled, Rebooter, tried again, rebooted some more, and gone round and round till the cows come home, and I still get a blank display with just a mouse cursor.

I'm using a 2018 MacBook Pro 15" with the i9 processor. I'm running 10.14 Beta (18A353d) and the latest DisplayLink 4.3 Beta 5 driver.

If I select "Mirror Displays" and then set "Optimize Display" to "MacBook Retina display", then It works (mirroring my display), but if I turn off the checkmark for "mirror displays", I get the blank screen again.

I've hit a brick wall for now. It's most annoying because it *should* be working.

Any suggestions are welcome.

My work PC was recently changed over from a Windows 10 machine to a 2017 MacBook Pro. Working at home I use a Plugable UD-3900 dock, which I have been able to get one dispaly wokring with the beta 5 driver form July. This works well, but I really like 2 full size displays.

As a workaround, my IT group gave me a thunderbolt 3 adapter that has 1 hdmi port, and 3 usb 3.0 ports. This has enabled me to use my 2 full size dipslays. I plug one into the adapter via its HDMI port, and then I plug my DisplayLink based dock into one of the usb 3.0 ports. The dock has a display plugged in via DVI. Both displays work, and I keep the MacBook Pro closed, running in clam shell mode.

My IT group will not allow an upgrade to Mojave when it is first released, so any fixes included in that will have to wait for me. This workaround meets my needs.

I'm seeing a lot of posts on the internet from people who had gotten it working under Mojave Public Beta 5, and then are experiencing the blank screen with cursor just like me after installing Mojave Public Beta 6. Especially those of us with the newer 2017/1018 MacBook Pros.

I hope I'm wrong, but it would appear that Apple broke it again with Public Beta 6.

I'm hoping DisplayLink can comment and either confirm, or deny that assumption soon so we can stop beating our heads against the wall trying to get it to work again or that Public Beta 7 comes out and fixes it again (one can hope).

I guess the big lesson here is to always come check the DisplayLink forums before installing ANY update. Unfortunately, I got my new 2018 MacBook Pro the SAME day that Public Beta 6 was released, so I wasn't even aware I was installing a newer Beta at the time, and didn't consider that the next Beta might break it again.

Hello Sofla,

There is something on the 2018 model. As far as I know, it is NOT a regression (meaning it never worked, it did NOT "stop working again") We have received logs and have done preliminary analysis and logged a bug report. That's what my last comment on the idea thread was asking for.
In the meantime, you can force AirPlay with our beta 6 as I left it online.

Both sides are still in beta.

Kind regards,
Alban

Thanks for the reply Alban, glad to know it's a known, identified issue and already being investigated.

I wasn't aware the Beta 6 drivers were an option for Mojave. I just installed them, and it's working via airplay, so that makes it at least usable for me until a permanent fix is found.

Thanks again for the quick reply and great info.

In the mean time, it would be great if Display Link could fix the problem already, ok...

The fix for the mac 2018 model will not come from DisplayLink.

I get that basically Apple breaking functionality they deem 'not supported' even though a number of their third party providers rely on it is a pretty epic dick move...

...but is there a possibility of a (non Airplay) fix for pre-Mojave versions?

If it's looking like a 'no' then the heads-up would be appreciated as I'm going to have to find something that can function with the hardware I have to use for work

@Sofla David; No problem for me on a 2017 MacBook Pro running Mojave Public Beta 6. I've also got an older 2013 and there are no problems.
