DisplayLink USB to HDMI Not Working on Mac Mojave: A Troubleshooting Guide

If you're experiencing issues with your DisplayLink USB to HDMI adapter not functioning properly on your Mac running macOS Mojave, you're not alone. Several users have reported similar problems, and in this article, we'll explore some troubleshooting steps to help resolve the issue.

One of the first things to check are security settings in MacOS. It may seem counterintuitive, but if the wrong sequence of installation occurs, you may need to run the DisplayLink uninstaller (restarting your Mac required), followed by a reinstall of DisplayLink 5.2 (another restart is necessary). This process can be frustrating, especially for those who have upgraded to macOS Mojave 10.14.

In our testing, we found that applying Kernel Extension first and then installing DisplayLink 5.2 resolved the issue with external displays not working. However, it's worth noting that DisplayLink still functioned as long as the Kernel Extension was applied.

For those running macOS Mojave 10.14.6, we've identified two scenarios where the installation of DisplayLink 5.2 may not work properly:

1. Installing DisplayLink before the Kernel Extension is allowed.

2. Installing DisplayLink after the Kernel Extension is allowed.

To troubleshoot this issue, you can try installing DisplayLink before applying the Kernel Extension and then restart your Mac. Alternatively, install the Kernel Extension first and then reinstall DisplayLink 5.2. Both of these scenarios may resolve the issue with your DisplayLink USB to HDMI adapter not working on your Mac running macOS Mojave.

Our testing involved two cases: we installed DisplayLink 5.2 before the Kernel Extension was allowed, and also after it was allowed. We found that installing DisplayLink 5.2 onto a MacBook running macOS Mojave 10.14.5 and then applying the Kernel Extension resolved the issue.

DisplayLink 5.2 has been available since early July, and with the recent release of macOS Mojave 10.14.6, it's essential to ensure that your adapter is working correctly. If you're experiencing issues with your DisplayLink USB to HDMI adapter not functioning properly on your Mac running macOS Mojave, try following these troubleshooting steps to resolve the problem.
