The displaylink plays a significant role in supporting Ethernet, display and a range of USB ports. So when there is an issue, your productivity is affected negatively and may further cause some fears of costs. 10.14 displaylink no longer working is a problem that may not be obvious at first since the displaylink seems to be fully functional as a USB utility though the connected screen fails to respond accordingly. This article contains a solution.

Best Way to Fix Displaylink Not Working on macOS 10.14

Displaylink ceases to work in 10.14 because the macOS Mojave update interferes with the operations of the Displaylink. If you experience this problem like some other users, the first though will be “my displaylink device does not work at all when connecting on macOS 10.1.” Upon making the macOS Mojave update, the Displaylink USB drier’s capacity gets disabled, thus does not display output. Various security reasons cause the latest update to limit the software usage as it utilizes kernel extensions. Display link has “DisplayLinkDriver.kext,” which is a system extension. Therefore, as the operating system limits the kernel extensions, it negates the Displaylink.

Inconveniences Caused

Upon the onset of the displaylink 4.1 not working on macOS 10.14 problem, you are bound to experience a lot of inconveniences, especially if this happens in a business setting since the corporate environment faces a serious challenge. 10.14 displaylink no longer working may press you on a hard place, since it compels you to work without the displays and USB ports. This does not go so well with conferences that require display of info graphics. On the other hand, you may be forced to revert to previous OS that has no such problems, which is then time wasting. If your business deploys Macs in its enterprise ecosystem, the disappointment of 10.14 displaylink no longer working will force you to expend a proportionate resources amount that include human resource and others, to implement troubleshooting solutions. These inconveniences are the reasons why businesses hardly consider Macs as they lack the trust to run a corporate ecosystem.


The good news is, resolving the Mac OS X 10.14 displaylink issue is absolutely possible and so you can relax because complaining that “my displaylink device does not work at all when connecting on macOS 10.14” will definitely go away. To start with, as a Mac user, you have explicit prerogatives to regulate your Mac’s behavior, in relation to the kernel extensions. This means that you can activate system extensions after the installation of Mojave so as to enable the unrestrained running of Displaylink. As you begin resolving the Mac OS X 10.14 displaylink issue, you need to take note of the warning message that appears as you install Displaylink, which prompts the disabling of kernel extensions automatically. If it does not appear, you could be among the many that never get the notice, which also means that it is time to deal with it manually. Fixing the issue manually requires you to revert the Mac Security & Privacy menu settings in the following way;

  • Access the Apple Menu
  • Choose the “Security and Privacy” option
  • Another page will appear; put in your admin login credentials
  • At the lower section of your screen, observe the notification claiming that "System Software from developer "DisplayLink Corp" was blocked from loading"
  • An “Allow” button that is next to it is the place to click, thus effect the changes you need in your system extensions to revert the system limitations.

This procedure of resolving the mac os x 10.14 displaylink issue is very simply and works effectively.
