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 :)

DisplayLink on 2017 and later MacBook Pros
 

I previously used a DisplayLink adapter to add a second external monitor to my late 2011 MacBook Pro 17", until it stopped working when I unknowingly updated macOS to an incompatible version. I stayed on top of this thread looking for a fix, but unfortunately the first one available would not fill my needs because of the resolution restriction and the lack of rotation support. Continuing to read through the thread over time, I decided that the best approach was to upgrade to a newer MacBook Pro, and ended up with the 15" 2018 model. It works great and easily supports my 30" main monitor and the 20" monitor beside it with the appropriate adapters. Apparently I can add up to four external 4K monitors. It works so much better than the DisplayLink adapter ever did, which was so slow that I couldn't really run anything that had a rapidly changing image and many apps with seemingly static displays would sometimes cause the driver to peg the CPU and be unusable with it. It eventually became my "documentation only" screen and then, of course, stopped working at all.

Now I can run whatever I want on either screen and it works flawlessly. Yes, it was expensive to upgrade my computer, but the MacBook Pro 17 was seven years old and had gone through three logic boards because of the graphics chip solder issue, which Apple covered but simply replaced with similarly flawed boards.

What I can't figure out is why anyone purchasing one of these 2017 and newer MacBook Pros would want to continue using the DisplayLink adapter, as some of the comments in this thread seem to imply. Do you really need more than 4 external 4K screens? Just go with an inexpensive USB-C to HDMI adapter or a USB-C to DisplayPort adapter, depending on your connection needs. You'll be much happier when your displays run with native support and you no longer have to carefully consider whether applying the next update is worth the possibility of losing your extra displays.

In my case, I need a 2nd monitor that fits in my backpack when I travel to ships around the world and does not require it’s own power source.

Unfortunately, there’s not a lot of other options outside of the Asus USB DisplayLink monitors that fit those requirements.

For my use-case, I have a 2015 model; the monitors I have are standard corporate issue Dell monitors with DisplayPort, occasional HDMI and DVI-D inputs.

This Mac has two Thunderbolt 2 ports, so I went with a one-cable (plus power) solution - thunderbolt cable to a Belkin dock.
Belkin dock then has two USB to HDMI adapters (which in turn adapt to DVI cables).
Belkin dock also has a second Thunderbolt to mini displayport dealie for a third monitor.

Now the USBs don't work I've got two dead monitors out of three. I'm a developer, so it's kind of a punch in the sack.

Corporate won't upgrade my Mac because it would involve a new dock + an expensive new machine and we've got a 4 - 5 year refresh policy.

They won't give me monitors that can daisy chain, as that'll be expensive.

I can't switch to a PC, I need a bunch of iOS / Safari debugging stuff which it isn't convenient to fake on a PC.

Basically, not everyone who has gone dark has the option to use fancy monitors or newer hardware.

So what is happening to support 10.13.6 - It would appear nothing!

I have users screaming at me needing DL. We can't wait for Mojave as in an enterprise environment it will be at least 2 months befoe we approve for use.

We need a final driver for 10.13.6 NOW.

I was not aware of those USB monitors -- they look like very handy gadgets!

Yes, I agree that if your company won't upgrade your equipment, it's a problem. I'm also an iOS developer and luckily my employer was willing.

Replacement
 

So is there an adapter out there that will let you have 2/3 monitors with 10.13.6? I'm willing to buy right now!!

@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.

If you have a USB-C Port available, this one works great:

AOC i1601fwux

What make and model of computer do you have?

Permanent Fix for Non-Mojave Users?
 

My 2011 Mac mini will not support Mojave when it is released.

Apple will be supporting it on High Sierra (and providing security fixes) for another 2 years.

Is there a plan for a permanent fix for users who cannot migrate to Mojave?

That AOC monitor uses DisplayLink just like the ASUS. Are you saying you have one and are not experiencing the issue?

The USB-C version does not.

Alternatively, the ASUS ZenScreen offers similar functionality

I have a MacBook Pro (Retina, 13-inch, Early 2015)

Unfortunately, not that I know of. That's why I upgraded to the latest MacBook Pro.

Hi,

I found this rather interesting article, about Kernel Extensions:

Whitelisting third-party kernel extensions using profiles:confused:

Something DisplayLink could take a look at, or did they done already :D

That implies that they have a working system extension, which they dont. A beta driver on a beta OS that runs on some hardware doesnt really count after like 8 months. The article discusses whitelisting system extensions using Jamf, if it was a whitelisting issue then users would have a prompt to manually add the extension. Non enterprise users wouldnt have Jamf most likely. Ive had to whitelist extensions in jamf before, it would be awesome if that was the issue as its easily fixed but unfortunately its not :(

OWC, Caldigit and HP had this working on their docks with zero downtime for users so this is a Displaylink issue not an Apple one.

Unfortunately, you're a little off on your assessment of OWC, Caldigit, and HP docks. Those all use Thunderbolt 3, not USB-C, despite the cable looking identical to USB-C. Those docks use either the "alt-mode" function of USB-C (which passes video data over the DisplayPort channel), or native Thunderbolt 3. Each of those are seen by the OS as a native display, and the other functions of those docks have work in a similar manner. That functionality is dictated by the hardware itself. DisplayLink does not use DisplayPort or Thunderbolt, it's a different set of hardware that pipes a number of disparate hardware functions over USB, and requires special drivers to be able to do that.

Thunderbolt docks are expensive to produce and are expensive to purchase. DisplayLink is a lower-cost alternative that most people find appealing because of that lower cost. Hopefully Apple is able to work with the DL team to help them get to where they need to go with this driver.

Thanks for the explanation i guess but you may have misunderstood my comment. I am very well aware of the differences between tb3 and usb-c. The manufacturers i mention make usb-c docks as well as tb3 ones. im using a usb-c OWC dock as i type this and while its far for perfect it works.

Unfortunately, us peasants on the current non-beta OS with Thunderbolt 2 are SOL.
Single DisplayPort out from my Belkin dock works fine. ONE external monitor works at the wrong resolution kindasorta. The other monitor (which is rotated 90 degrees) is basically dead.

Yay. And this has been the situation for six months for anyone who didn't upgrade like me. I can't roll back as I need the latest Safari. Yay.



Yay.

PS Spellcheck the displaylink.com homepage. Connectivitye, eh?

What is the plan for users who cannot upgrade to Mac OS Mojave?

This is the third time I have asked this question. Silence speaks volumes.

If there is not going to be a permanent fix for High Sierra, it is only proper that you let us know so that we can make some alternate plans.

That is simply because that has been answered already and it is totally inappropriate for me to comment on what another software vendor might or might not do in a future release, or even if they have any new release planned.

After testing completes in the next few days, we will issue a 4.3 release to allow more resolutions on 10.13.4+ than the current HD and FullHD.

Regards,
Alban

Apologies if I missed it.

But I have been back through the thread and see no answers regarding a possible solution for High Sierra users who cannot upgrade to Mojave because it will not support their hardware.

Haha, is 1st April. I doubt we will see a final version for 10.13.4+

DL concentrating on Mojave support, perhaps Apple backtracked a bit in Mojave on what they changed in 10.13.4+ that killed DL, who knows, but I doubt will not see anything more than a beta and res of 1080p in HS.

The good news is there are now 4k USB-C screens that you can daisy chain, they also have USB-A 3.0 on the back so you can plug in a USB-A to Ethernet adapter. You just plug your Mac in with the USB-C single cable, Screen Ethernet, Power - Good bye DL docks, goodbye crappy drivers.

Have a look at Lenovo ThinkVision P32u

Almost 9 months and no real fix, Display Link is a joke.

+1 on OSX support.

Mirroring or a single display is not "support" I can do that a number of different ways.

In our case we have very expensive human scale arms+docks that use displaylink. There is a very critical team within our company that runs an OSX based platform. The one issue, displaylink software. We've asked HumanScale to find another way, to get away from DisplayLink or at least give us another dock/OSX compatible option and to stop saying it's product is OSX compatible at all.

I joined the forum to make this one complaint. We've been waiting for new drivers since early 2018.

They state OSX is "supported" and brochure pictures have a mac book pro in them. :)

OSX 10.13.6 today.

What happen to the rest of the entries in this thread. It used to be at page 58 and now back at page 52. Seems everything has been removed?

I've been watching this thread for months, and it has never been bigger. I know because I keep updating the page number in the bookmark link as it has grown so that it takes me to the last page and I can keep updated.

Indeed, never been bigger than this.

So, the workaround was working. Now Airplay does not recognize the USB monitor.

I am on 10.13.6, MacMini late 2012 and I have downloaded the 4.3 beta 5. I have uninstalled, reinstalled the Beta 5 a few times. Powered off/on, still the 3rd monitor is blank.

I have followed the FAQ install steps and gone into System - Security and Privacy and DisplayLink is enabled under Accessability.

Is there something I can do differently? I am wondering if the actual USB device has gone defective.

Would be best if you raised this in a separate thread. Can you post logs so we can see more details about your setup?

Cheers,
Michal

You know what "would be best"? Fixing the problem, that "would be best". I know, it's only been 9 months now... maybe one of these days you guys will fix the problem.

Update: September 12th
Dear DisplayLink macOS users,

DisplayLink has worked for many months to maintain support for its users during the transition from macOS High Sierra to Mojave. While functionality such as Ethernet and audio or charging, where implemented, is unaffected on all releases, display connectivity has been limited on macOS releases from 10.13.4 through 10.13.6.

Users with access to Apple 10.14 Mojave previews released since 30th July confirmed full support was restored for multiple extended DisplayLink displays.
We are performing wide scale testing of v5.0 beta released today against current and upcoming previews to release v5.0 upon general availability of 10.14.

Users on High Sierra 10.13.4-10.13.6 should install the newly published v4.3 as the workaround to enable one extended USB display now supports additional resolutions.
An FAQ details how to enable Apple AirPlay with DisplayLink display for extend or mirror mode.
DisplayLink driver v4.3 released today is also applicable to Mac OS X 10.12 and other macOS 10.13 versions.

Some MacBook 2018 models on 10.14 previews may experience black extended display(s) with only mouse cursor. DisplayLink driver v4.3 Beta 6 stays available to force an AirPlay extended display on these machines until a fix is distributed.

We thank you for your extended patience, we continue to value your feedback and support.

Kind regards,
Alban

10.14 Public release is September 24 as announced today. Whats the position against the last beta of Mojave? Are you in a better position than late last year when the beta of 10.13.4 was first released? Is there a release date planned for 5.0 drivers that correspond with Apples date or there is going to be a delay? Is that what the words surrounding the testing is referring to?
