I have uninstalled, ran recovery mode with kextcache command, reinstalled using the latest beta3 driver, and the dock/DisplayLink does not work at all. Screens don't even power on. Not seeing how this is resolved.

Updating the Dell D6000 firmware to A03 and installing the DisplayLink 5.2.1 Beta 3 drivers worked for me - but updating the firmware was the real fix. It looked like mine was never updated.

Here's a link (https://downloads.dell.com/FOLDER056..._A03_T8Y8T.exe) to download the firmware installer to anyone else reading this (need to install on Windows, plug the power into the wall and the usb into the computer)

Please upgrade your macOS to very recent Catalina 10.15.1

Together with DisplayLink driver 5.2.1 beta 3 all major issues should gone.

Upgraded to 10.15.1 just now and still not seeing anything on a dual monitor 2x display-port setup. Single monitor HDMI works fine.

Upgraded to 10.15.1 and installed Beta 3 for Display link. Single monitor does not even work!

I'm having similar issues as the two posts above me. I rolled back to 5.1.1 and was able to get one of my monitors to work, but with 5.2.1 beta 3 I had and then lost my one functioning display when I tried to reinstall the drivers.

Using the latest drivers and the latest catalina update also did not work for me :(

I already posted my diagnostics. would really love to get some help here.

This worked.
 

MacBook Air 11inch, early 2015. 2.2GHz i7
this solution also worked for me. Uninstalled DisplayLink then installed 5.1.1. Nice to have my monitors back.

I have had exactly the same experience. I'll try the 5.1.1 solution and see how that goes.

Update: 5.1.1 gets both external displays working again (yay!), but I should note that the dock doesn't work on one, although that limitation I can live with.

MBPr 15 2018 - Display just blinks when plugging in Dell 6000
 

After I updated to 10.15.1 on my MBPr 15 2018 - the display just blinks after plugging in the Dell 6000.

I am running the 5.2.1 Beta 3 drivers now. I tried to rollback to the 5.1.1 but the duel and single display (HTML) were blank.

Help!

Hi, I have the same issue as rarutu.
Right after apple Catalina Update (10.15.1) Display link stop working.
After Installing Catalina and before the last update the dual monitor and everything were working.
Beside the fact that i couldn't charge my MAC from DisplayLink anymore.
However after the 15.1 update nothing works anymore. Only mouse and Keyboard.
If i connect and disconnect the DisplayLink USB type C cable from my laptop and reconnect it My laptop monitor start to flicker like trying to connect to the external monitors. But the external monitors does not turn on.
In attachment there is my log.
It would be great if you could help pr release an update as i can use only the laptop monitor now which is very counter-productive.

Thank you!

@Cyfer

did u try to plug in the docking station first and after that the charging cable? right now this is how i use it ... 2 different setups ... both work with this "hack"

So I am not Cyfer, but I was struggling this morning to get it working with the same issue they had. Then I tested plugging in the dock, and then plugging in a separate power cord and poof my displays started working again. I have gone through so many different versions of the driver and am currently on 5.1.1 though not sure it matters which one as 5.2 worked yesterday right after the update to Catalina then stopped working today. Not sure what is going on.

@jjuel5

this worked for both Beta 2 & 3 for me

The Charging is not an issue, even before 15.1 i was using an external charger for that. But at least i was able to use the monitors, keyboard and mouse with displaylink.
But now after 15.1 nothing works even if i have the charger connected and connect the Displaylink.
It is clearly a software issue since a Catalina Update broke it.

Hi All,
I just given up on this and i solve the problem buying another dockstation which has no problem with MAC Catalina

Can't find the app
 

My problem is that I can't find the DisplayLinkUserAgent.app anywhere. It's not under any heading in privacy at all.

Update Firmware
 

There are a lot of right answers in this thread but one that is seemingly missing is to update your docks firmware. This requires a windows computer (don't try with a VM).

https://dl.dell.com/FOLDER05691661M/..._A03_T8Y8T.exe

Neither do I, and I've re-installed Cataline 2x now, and DisplayLink 5.3 three times, but the DisplayLink UserAgent box never appears in Screen Respond box. I manually put it into Accessibility, but no luck getting my monitors recognized: they don't even appear on the "Display" in System Preferences.

Puzzled.

We have identified that part of Dell D6000 docks produced between mid 2018-mid 2019 contains USB Hub firmware issue that was uncovered by macOS Catalina 10.15.1 release.

There is a for that.

Please update your dock hub using "Dell Firmware Update Utility":

If hub firmware does not help then please submit your logs using that tool:

[3] This is also my experience ... I can't for the life of me workout how to fix it

Submit the logs to who? email?

I am running the latest 5.2 driver, Catalina 10.15.1 and I get the same as many others. Nothing shows up in my Screen Preferences and my screen is black.

My kext is showing loaded properly and notorized. I disabled SIP and touched /Library/Extensions as well. I don't get any popup about allowing access for Screen Recording and it doesn't show any apps listed for Screen Recording in my System Preferences->Security->Privacy.

I am willing to try anything at this poing.

Update 2: The 5.2.1 version announced on 23rd Nov is installed and working, so far with no issues. :)

Hi Signal,

Please attach them to the post, it will be accessible only to DisplayLink team.

I hope that you have the latest 5.2.1 drivers installed:
https://www.displaylink.com/downloads/file?id=1478

I am attaching them to this post. yes I am running 5.2.1, i just downloaded and installed it the day of my post.

Hi Signal,

It seems that you don't have DisplayLink docking station connected.
It is visible in "About This Mac"->System Report->Hardware->USB tree.

Can you check the usb cable or power cable?
How the dock behaves on Windows?
Are other devices like mouse connected to the dock working?

I have an iMac and its plugged into my Zenscreen via USB-C. It powers up the Zenscreen but its just blank.

edit: usb 3 powered hub fixed the issues

Okay, so I finally got DisplayLink 5.2.1 working with Catalina 10.15.2, after following all the directions and performing a bunch of installs/uninstalls (none of which worked...lol).

I have a Mac Mini (late 2012) and I was running High Sierra. I figured there would be some issues updating DisplayPort, after updating to Catalina (DisplayLink has historically,never been an easy install...that's why I always perform a backup before mucking up my machine). I have a 15" AOC monitor which has been getting its power from the USB ports on my Mac Mini.

Anyway, after updating to Catalina, I installed DisplayLink 5.2.1, allowed permission for the install, made sure that DisplayLink was enabled in the "Accessibility" control panel, made sure that it was enabled in "Screen Sharing", and made sure the extension was loaded in "About this Mac" | System Report | Software | Extensions.

After doing that several times (with no luck), I figured I'd try putting a powered USB 3.0 hub between the monitor and my Mac. That did the trick.

It seems that, perhaps, either Mac OS X Catalina or DisplayLink no longer consider the two onboard Mac USB ports sufficient enough to power the monitor.

That may or may not be your issue, but it's worth a shot (I believe newer MacBooks have USB-C and that specification is supposed to, theoretically, provide adequate power). The main downside is that you wouldn't be able to be free from being near an AC outlet.

edit: usb 3 powered hub fixed the issues

DisplayLink Forum, you're my only hope...
 

Like most of the other users on this thread, I have tried just about everything and I am about to give up, get rid of my 2017 13" MacBook Pro and say f*ck it all, but I want to give it one last shot. Here's what I am working with:

I have a 2017 MacBook Pro. Here are the stats:

I was running the MacBook on a separate stand with the screen closed connected to two LG 4K Ultra monitors connected via USB-C - HDMI inputs on the monitors. Running both Mojave or High Sierra, no problems at all. Both monitors ran at high resolution, docking/undocking no problems at all. As soon as I updated to Catalina, the wheels fell off - I could only get one monitor at a time to work and it defaulted to the MacBook display resolution. I tried connecting both USB-C cables, one at a time, switching them out - same thing - only one display will work, never both. I have been uninstalling, and installing the DisplayLink USB graphics software since it October and installed the latest update with the same result.

I also followed the instructions for activating Screen Recording. It's odd, but I have no options under Screen Recording in System Preferences:

https://drive.google.com/file/d/1jeC...ew?usp=sharing

I have also tried using USB-C - HDMI and USB-C - DisplayPort cables with the same result. I also followed Apple's SMC reset instructions without success.

I used to work as a software engineer and think my QA skills are pretty solid but this one has really got me. Would love to hear any suggestions on why this is not working and what changed since Mojave and High Sierra

Another try for you Catalina sufferers
 

I recently upgraded to Catalina even though I had issues in the past OS updates of breaking the docking station with High Sierra.
I tried several of the recent versions of the DisplayLink driver. Nothing I could do would get it to prompt me to add the useragent to Screen Recording privilege with my primary account.
Finally I decided to install the software and then login as a different, local user... and do the rest of the setup that way... this time it prompted me as it should and now I am typing this from one of my external displays!
So... try installing it clean and then login as a new user and plug in the dock and the prompts should come up.
Hallelujah!
Hope it helps someone...

(Unpowered) Hub Works for me!
 

I placed an unpowered VAVA USB-C Hub between my D6000 and my MBP 2019 (10.15.2) and the displays came right up.

Connection looks like this:

Dual 4K Dell monitors (and various USB peripherals) -> D6000 -> (using USB-C to A converter) MBP (running DisplayLink 5.2.1).

Still not working DUEX
 

Tried several times installing and deinstalling but DUEX still not working. Test file attached

DisplayLink doesn't show up in Privacy settings
 

Hello, I followed all the latest instructions but the DisplayLink option doesn't show up in the Privacy settings and I can't find a way to add it manually.

How did you do?

I ended up connecting my MacBook to power directly and then then Hub to another USB port - that worked for me ...

Marc
