DisplayLink Manager (don't know version number, but I downloaded and installed it sometime in June 2022)
Symptoms / Steps taken
- DisplayLink Manager stopped working overnight. Was working fine yesterday to support a dual-monitor setup. Today, no video appeared on the monitors.
- I used the DisplayLink Manager icon in the top MacOS menu tray to see what was up, but it gave me a never-ending rainbow pinwheel.
- I verified that my Docking Station is present in the USB tree in System Report:
- I attempted to force quit DisplayLink Manager, but the application did not appear in the Force Quit menu.
- I restarted the computer several times to try and resolve the issue. No success.
- I unplugged and replugged every cable in between restarts and while the computer was on. No success.
- I attempted to install the DisplayLink Manager Login Screen Extension, but it got stuck at "Opening Package" or something. I restarted the computer.
- I downloaded DisplayLink Manager Graphics Connectivity 1.8. I don't remember which application I used (either the Login Screen Extension or Graphics Connectivity 1.8), but one of them had a DisplayLink Uninstaller. I used that to uninstall DisplayLink Manager.
- I then attempted to install DisplayLink Manager Graphics Connectivity 1.8. I was met with the following message:
So... here I am. Reporting this issue in case anyone else has encountered something similar.

In regard to the inability to install DisplayLink Manager 1.8 (which you mention at the end of your post), can you please confirm that the macOS 'Installer' application has been granted access to the location where you downloaded the DisplayLink Manager Application file?
You can do so by following these steps:
1. Click on the 'System Settings' icon (looks like a gear) in the macOS 'Dock' at the bottom of your screen
2. Within the System Settings application that appears, scroll down in the list of items on the left-hand side and click to select the option 'Privacy & Security'
3. Within the list of items that now appears in the right-hand side of the System Settings application, scroll down in the list of items and click to select the 'Files and Folders' option.
4. Once within the 'Files and Folders' option, you should see a list of items presented. Please click on the right-facing arrow next to each entry that is present in order to expand the setting for that entry.
5. Check to ensure that under the 'Installer' item that the location of the DisplayLink Manager Application file is both listed and enabled using the toggle switch. For example, the 'Downloads Folder' location.
This is important, because if the permission to access the file has not been granted to the Installer application then that can cause problems.
