Plugable DisplayLink products and macOS Catalina 10.15

SUMMARY: Users updating their Apple Mac system from macOS Mojave 10.14 to macOS Catalina 10.15 can experience problems with Plugable products based on DisplayLink technology not working. Plugable does not officially support using our DisplayLink products with macOS, however we want to provide some background information and a procedure that can potentially get things working again.

** Update 12/3/2019 – With the latest update to the DisplayLink macOS driver, the ‘additional’ instructions provided by DisplayLink on their support site (to be executed within Recovery Mode) that were required in some instances should no longer be necessary, and as a result DisplayLink has removed the information from their website. We have kept the information within the blog post for historical reference, but have struck it through to indicate it is no longer required. **

On Monday, October 7th Apple released macOS Catalina 10.15 for supported laptop and desktop systems. As with any other major operating system update, there is also the possibility for existing peripherals and applications to not work as expected.

We speak to some of these issues in recent blog posts:




In this post we want to speak to how macOS Catalina affects Plugable products that use DisplayLink USB video technology, which at present include the following products:

UD-6950 Docking Station –
UD-5900 Docking Station –
UD-3900 Docking Station –
UD-3900H Docking Station –
UD-6950H Docking Station –
UD-ULTCDL Docking Station –
UD-ULTC4K Docking Station –
UD-PRO8 Docking Station –
USBC-6950-DP Display Adapter –
USBC-6950-HDMI Display Adapter –
USB3-6950-DP Display Adapter –
USB3-6950-HDMI Display Adapter –
UGA-4KDP Display Adapter –
UGA-4KHDMI Display Adapter –
UGA-2KHDMI Display Adapter –
UGA-3000 Display Adapter –
USB3-3900DHE Display Adapter –
UGA-165 Display Adapter –
UGA-VGA-165 Display Adapter –

In brief, our DisplayLink-based products can be made to work with an Apple Mac system running macOS but this is not something Plugable officially supports at this time and we do our best to call this out in our product listings.

While DisplayLink (the separate company that makes the chips used in our DisplayLink-based products and does the driver development –> ) have released driver versions that work with macOS that some have reported work with our products, this is not officially supported by Plugable.

With the recent release of macOS Catalina 10.15, Apple has made changes to the operating system that require an updated beta DisplayLink driver and a few special steps during the installation process in order for any DisplayLink-based device (Plugable brand or otherwise) to work properly.

As a courtesy we have provided detailed installation instructions (and a video walkthrough) for removing any existing DisplayLink drivers and installing an updated DisplayLink driver on a macOS Catalina 10.15 system here –>

* Please pay particular attention to the security processes shown in steps #11, #12 and #13 of the install guide. These need to be completed in order for the process to work.

** We have had reports that even after following the installation instructions the DisplayLink device is still not working. Should that prove to be the case, first ensure you have a full system backup using Time Machine as a precaution. Once the backup is verified, please follow the instructions provided by DisplayLink here –>

In summation, while Plugable does not officially support using our DisplayLink-based products with macOS most likely things can be made to work. Customers updating from macOS Mojave 10.14 to macOS Catalina 10.15 may see their DisplayLink device stop working. Removing any existing DisplayLink drivers and installing an updated DisplayLink beta version driver may help, and we have provided a detailed procedure for doing so.

If you are using a Plugable branded DisplayLink-based product with macOS Catalina 10.15 and are still experiencing issues using the device after having followed all of the procedures referenced above, please keep everything connected (even though not working) and send the output of our diagnostic utility PlugDebug –> to us directly via and we will do our best to try and help.

    Reached out to support regarding me following the previous set of instructions, and in 24 hours I got a reply from Bob referring to this page and an additional set of instructions which needed to be applied in Recovery Mode.
    Followed the instructions, and my secondary Apple Cinema Display was brought back to life like magic!!
    Really appreciated Bob’s prompt response and pointing me in the right direction to resolve the issue after the MacOS 10.15 update.

        Hi Max,

        In the time since this post was published, DisplayLink has updated their Mac driver installation process so that the additional steps Ray mentioned (within Recovery Mode) are no longer required. The basic instructions we mention in our blog post ( should be sufficient to install the latest DisplayLink driver on a Mac and we have updated the post to reflect this.

        If you are using a Plugable branded DisplayLink-based product with macOS Catalina 10.15 and are still experiencing issues using the device after having followed those instructions, please keep everything connected (even though not working) and send the output of our diagnostic utility PlugDebug –> to us directly via and we will do our best to try and help.

    I reached out to Plugable’s support team and got in contact with Pat Pennell who was super nice, understanding, and patient. I was able to get help resolving an issue with a docking station (Model UD-6950H) working with a 2015 model Mac. Plugable states that it does not officially support Mac products, but they do support their customers. The experience I had resolving this issue and others in the past with Plugable have all been very pleasant. Thank you Plugable and thank you Pat!

    Using Catalina with DisplayLink. Walked through installing the new Beta software driver, check the box for screen recording, etc. Both monitors work, but mirror each other. Can anyone help?

        Has something changed since last week? After 2 support calls we were told to reinstall Mojave.

        • Mitchell F Reply

          Just to clarify for those who may be following this comment thread — the support calls mentioned were NOT provided through Plugable but rather one of our competitors. Plugable does not offer phone support nor do we advise our customers to roll back to macOS Mojave. Thanks!

    Macbook Pro 2014 / MacOS Catalina 10.15.1 / Asus MB168B+ monitor.
    Uninstalled & reinstalled the DisplayLink driver about 5 times (reboot, reboot, reboot), no luck.
    System Preferences -> Privacy & Security -> Screen Recording: I didn’t have any DisplayLink option displayed.
    Browsed to
    And, presto, DisplayLinkUserAgent was no an option under “Screen Recording”.
    Unlock -> Check box, and it works

    Hello, I recently got a Mac OS 8 GB update to Catalina, and my 2 display monitors stopped working. LG (HDMI) and Dell (VGA).
    I have restarted my Mac ~10 times trying to figure this out. The keyboard,mouse and LAN connection are working fine. But the displays have stopped responding.
    Requesting your help.
