10.13.4 Displaylink no longer working

There are a few things we can do. One is run one display off your dual link adapter and connect another display directly from some of the free ports. The plugable dock I use also charges the Mac so there’s one free port (I have the non touchbar Mac) or you can get a dock that will work but it’s pretty pricey. This dock will work for sure:

The above dock requires no drivers and will also charge your Mac. There are others like this one from elgato and Belkin, but they are all at the 300 price point.

You have to either restore via time machine to a date prior to getting the update or re image the computer with an image that is below 10.13.4. Display link has been working on this since beta for months and are no closer to a solution. There may be no fix other than to buy a more expensive dock that doesn’t use driver such as the OWC usbc dock which is about 300.

I have the same problem and need that third monitor. Apple is being inconsiderate and nazi-like on this. Our Mac Mini computers have been very efficient for us, but I guess no longer. I dont think I am ever going to migrate to another "update" in the OS.

Indeed, the Mac OS update 10.13.4 (17E199) does not support my Starch USB-C hub display link driver anymore. Now I am down from 4 displays to 2 (HDMI is working, but the two Display port outputs are not).

Really sad, because my productivity is proportional to the amount of square pixels that I see....

Thanks for the info, i had already found that, but this is no solution by any means. All this beta driver does is clone your display. What we need is EXTENDING or MIRRORING, otherwise apple just made our "displaylink" completely useless, who's returning our money?

I hope they're working on a solution ASAP.

There's a reason a proper dock costs big $$$. DisplayLink is simply pushing data over USB, software does all the work. You don't get any acceleration and you can't display HDCP protected content, it's only because of relatively beefy hardware that it works.
Now that "driver" stopped working, that happened with first beta of 10.13.4, quite a while ago.

DisplayLink wasn't able to produce a working driver.

And it's Apple's fault... how?

I have a shelf full of unsuported hardware - USB colorimeter with drivers for Win98, a Blackberry cradle that fails to work over USB 2.0 because it used some undocumented glitches that stopped working in recent chipsets, Soundcards that stopped working with WinXP, TV Tuner that apparently only properly worked on one version of Vista... Should I blame Microsoft for not making the drivers? Should I blame Intel for not making their chipsets as quirky as the old ones?

Just because lots of people were tricked into buying junk doesn't mean Apple should go out of its way to support it.

Hey man, many of us developers are looking for more screen space for code development and testing and could care less about HDCP protected content. DisplayLink embedded chip and driver for $40 to $70 fit the bill for use. You may not realize it but what you think is hardware today is more often software under the hardware cover. Nobody has been tricked at all into buying "junk", Apple is hardening the field so it can sell overpriced items and get away with it. Nobody in Apple likes good product that sells for 13% of their pretty boxed item. So buy your $$$ Apple product, no prob. But the rest of us, we made the investment in DisplayLink based products, were very happy, and are not happy with how Apple has choked us hard... because they can.

A display link device isnt JUNK to ME. I need 3 monitors and its the only way I saw to get it. It IS apple's fault for NOT announcing along with the "update" that something as prevalent as display link devices would turn into bricks. I am ****** off at Apple. Too bad the only completion is WORSE, or I would migrate to it.

Apple talks about intuitive software, but I think they suck at it to an alarming degree. I find the whole iCloud incomprehensible , as well as iTunes. The software is still written by programmers, FOR programmers, not normal people.

We should sue apple for not telling us all that display link devices would become useless and NOT to update if you want to continue using them. Its only fair.

Unfortunately, windows is worse ! And Apple knows it, which is why their programmers dont care about the customers who have display link devices. I think we all should sue apple for making our devices into bricks WITHOUT warning us that their "update" would have that result. Its very inconsiderate, and I hope they fix the problem one way or the other, although I am expecting they knew what they were doing and for some business reason they proceeded with it anyway.
