10.13.4 Displaylink no longer working

Apple is not going to include a change to the graphics subsystem in a security update. For Apple, a quick fix for even minor issues would be 10.13.5 or 10.13.6. Since that likely overlaps with 10.14, I suggest everyone who wants to use DisplayLink technology stay on Sierra until the fall.

Apple got rid of display link for their own reasons, and wont backtrack on that EVER. All we can do is try and protect ourselves from Apple at this point. If they make their changes so that my present equipment doesnt work anymore, I will just have to buy other equipment so I can continue on with what I need to do. Apple isnt the only game in town for sure.

I use Mac for home and I use display link pluggable dock.

This is not just a corporate use issue, this is a problem with Apple. When they pull these kinds of things when you wake up and your setup that you paid a lot of money for no longer works, you have no trust ever going with their products.

It's like Apple goes out of its way to make their products not work with other systems. I have zero trust in what Apple may do the next day.. And their customer's interest is not what they care about.

If Microsoft did this, Apple would've mocked them on TV for years.

Shame..

I had the same issue (Macbook Pro 2017 13" with touchbar) I run multiple displays through a SIIG dock with 4 display ports, just updated to Mac OS 10.13.4 last night and have wasted half the day in the office today restoring back to 10.13.3, I can't work without the additional displays, as I'm sure MANY professionals that are shelling out $2200.00 for a laptop would say the same.

SIIG is stating that Apple has removed the ability to run video over USB, which all the ports on the macbook pro are (USB-C). Haven't tried my apple adapter with a single HDMI because I use more than one external display. Very frustrated and stuck on 10.13.3. Won't be updating until apple restores the functionality on future OS updates.

Apple you have really dropped the ball on this one and need to get this fixed.

It is very disappointing. I for one would not have "upgraded" if there was a warning this would kill mu USB video.

I just have it running to display my security cameras off the main screen so I can see anyone coming. My workshop is in the back yard. Nothing fancy in the way of graphics.

There have been some who say this in not Apple's problem but I see it as fully in their court. Something that was working is no longer. The only variable is the upgrade.

Apply is getting just as callous as MS.

As I said in starting, very disappointing!

I have been using Apple products since the Mac Classic days. Thumbs down Apple that you are not at all interested in fixing this. Another indication that you have got too big and lost your connection with you user base.

I am gifting this 27" Mac to my son so the USB video problem will not matter on this machine, but will in no way update my other Macs! I would like to turn off all future updates if I can.

Thank you for posting this update. I do not seem to get notifications from DisplayLink even though I had signed up for them, nor do they apparently tweet a notification of the update. It does appear to work. Again, thanks.

There is certainly a wealth of misinformation on this thread.

The truth: DisplayLink docks and USB boxes work fine in High Sierra through OS 10.13.3.

With 10.13.4, Apple broke all 3rd party display options with one exception. This includes eGPU over Thunderbolt 1 & 2, Duet Dock and all other iPad display apps and all boxes tat require DisplayLink Drivers.

The only exception is eGPU over Thunderbolt 3, to which Apple is reinforcing their commitment as announced at the WWDC.

Apple has not acknowledged any bug and it’s very possible this was done on purpose as eGPU over Thunderbolt 1 & 2 has been problematic. Easiest way to deal with that is to end all support.

DisplayLink and a few of the eGPU card makers are trying to come up with drivers to wrk around this. Duet Dock seems to think Apple will “fix” this. If Apple doesn’t think it’s broken, I wouldn’t hold my breath. As for the others, they may or may not come up with a solution.

The DisplayLink 4.3 drivers provide a kludge that some may be able to use—I‘m not one of them. For those who can, go go go.

I’d like to see drivers that reenable my box. I make my living with my Mac and am stuck at OS 10.13.3 until a solution is released or I buy a new Mac (not yet). 10.13.3 is a stable OS and meets my needs for now.

A PC is not an option for me. The CRM I use works much better on a Mac and runs poorly on the PC. Been here, done that, no thanks! Never again.

There are USB C to HDMI adapters as well as USB C docks with HDMI ports. There are limitations on the quality of the video what they support if you do not have a Mac with Thunderbolt 3 through USB C (if you have been using DisplayLink boxes, it should be comparable).

This are also simple USB C to HDMI adapters such as this:

If you have Thunderbolt 1 or 2 available, there are inexpensive adapters that will give better video results. Like USB C to HDMI above, these are adapters, not 3rd party solutions—if you have the port, these work fine. There's no advantage to the Apple branded unit as there is no proprietary chip inside.

A few Macs have TB 3 available through USB C: This includes all Mid-2017 and later iMacs, iMac Pros and MacBook Pros.

All 3rd party monitor solutions were killed in OS 10.13.4 — 10.13.5 except eGPU over Thunderbolt 3. This may change if DisplayLink and some of the eGPU card makers write new drivers. Even if they do, will those be forward compatible into 10.14?

I'm with you on this. Even if new drivers are written, USB 2 monitor boxes are yesterday's tech. I need to run 2 monitors off of my iMac, currently impossible without one being USB 2. With any iMac newer than mid 2012, that isn't an issue plus they support Metal graphics as required with OS 10.14.

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 am having the same problem at the company I work for. We are exclusively Mac based, and we have quite a few computers from 2012 to the latest and greatest. Many of the administrators want to have two external devices but they are using MacBook Air computers. Before 10.13.4, I connected one thunderbolt to HDMI, and a USB3 to VGA and everything worked perfectly. I have successfully downgraded two computers I installed 10.13.4 right away and found the break but now I have to make sure to never upgrade older computers with this setup past 10.13.3.

Moving forward, I'll make sure new administrators get a MacBook Pro which I can install two external displays, but the multiple adapters to get the job done is ... not pretty.

Did you use the Snapshots feature of APFS?

Downgrading to 10.13.3 was how I discovered it on my iMac. That is so amazing.

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.
