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.
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:

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 –> https://www.displaylink.com/ ) 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 –> https://plugable.com/drivers/displaylink/mac/#install_catalina
* 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 –> https://support.displaylink.com/knowledgebase/articles/1925041-macos-catalina-10-15-black-screen-or-only-one-mon
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 –> http://plugable.com/support/plugdebug to us directly via email@example.com and we will do our best to try and help.
