10.13.4 Displaylink no longer working

I can tell you that this adapter does permit an HDMI display to operate from a DP port on a macmini 2012 on 10.13.4, BUT there is no way to get any of the adapters I found to deliver a third display operational from USB. You have to downgrade to 10.13.3 and never again trust apple's "improvements" in new macOS releases. They just dont tell you when they are actually "downgrading" . They are a big company and dont care about customers I guess.

Agreed. This isn't just limited to adapters and docking stations. I recently bought an ASUS portable monitor in order to have 2 displays on the road. It plugs in directly with a USB cable to my MacBook Pro. These monitors rely on DisplayLink drivers as well.

Now you can read responses to peoples questions on Amazon about these monitors and if they work well with Macs. The answer is now,: "they did until 10.13.4".

I ended up having to go all the way back to Sierra, as I just bought a 2016 refurb from Apple only a month back and didn't have a TimeMachine backup yet of my new machine. So maddening.

The situation is unchanged in OS 10.13.5 and the 10.14 beta.

This is a byproduct of Apple ending eGPU support over Thunderbolt 1 & 2 which had been problematic. Apple is unlikely to fix this because they don’t think it‘s a bug.

So, will DisplayLink be able to write a compatible driver? They’ve had months now.

Since my 2010 iMac is incompatible with 10.14, I’m in the market for a 2012 or later anyway, With a pair of TB ports, I will no longer need my DisplayLink box to run two external monitors.

I didn't think of that. I have a bootable USB thumb drive with the 10.13.2 installer. I tested downgrading on a test machine before I performed the actual downgrade, and in both real cases I ran a full backup of the computer first. The only side-effect that I encountered in the test and the actual downgrade was the keychain needed to be reset.

There are USB C to HDMI adapters as well as USB C docks with HDMI ports.

You mean *Type-C* adapters which do NOT rely on USB (unlike DisplayLink which does).

(My Type-C adapter does rely on USB and is broken by this update)

All of that is good but for those who are maybe not going to be able to upgrade to 10.14, which there are situations in a commercial environment where that will be likely, but are on 10.13.4 or higher it seems as if there will not be a solution. The "workaround" with using AirPlay is not stable and only sometimes works. This means that MacBook Airs from 2017 can only use one external monitor which isn't a lot of screen real-estate. Sure you can use an ultrawide monitor but unless you get something that is 4k, which are expensive, then the scaling does not give you the full advantage of the amount of screen that you get. People have a right to be asking questions.

Yes I’m on 10.13.4. So it only works if I leave my MacBook open. If I close the lid it displays as though it’s extended but it isn’t. When opened it behaves as it should.

While it's not ideal, I pulled out my old HDMI to thunderbolt 2/display port adapter and plugged in directly to the laptop. It gives me the extended display until they fix this issue...

Has anyone tried the latest macOS update (10.13.5) ?

After upgrading to 10.13.4 my display link monitors no longer function.

Exactly what are "displaylink monitors"? Do you mean DisplayPort? Read Apple Mini DisplayPort adapters: Frequently asked questions (FAQ) - Apple Support.

I can find no reference to "displaylink" in any of Apple's documentation. Are non-Apple drivers required to use your external displays? Who makes them?

Hello BradSP,

I have heard that 10.13.4 breaks those virtual display drivers. I have one of them for my iPad but I uninstalled it a long time ago. It caused my iPad to freak out any time I connected it to anything.

You are on a displaylink dock on 10.13.3?

Try mirroring to a TV... I’ll wait...

Also try Accessability zoom...

Also, plug your DisplayLink dock then shut the lid, will it wake up?

Also, grab a windows laptop, close the lid and reopen it....

If this persists it will be interesting to see if Macs survive for anything other than home use.

That's probably being a bit extreme. I understand about DisplayLink docks, but enterprise isn't everybody outside the home.

There will always be the creative business professionals, who will never be satisfied with the limitations of DisplayLink; they always plug into DisplayPort or at least HDMI for the highest possible graphics quality and resolution on their high-end monitors.

I see a lot of Macs in education and science who are perfectly happy with HDMI or DisplayPort, or with the USB-C or Thunderbolt single-cable docks, so are not affected in the least by whatever is happening with DisplayLink.

I'm not saying DisplayLink is unimportant, only that its failure is not going to come close to killing Macs outside the home. Lack of DisplayLink is going to have a huge impact on specifically enterprise who only accept Macs to the extent that they work like PCs. But outside of corporate enterprise, DisplayLink is nearly nonexistent as far as I can tell.
