Hi everyone,

I recently updated my Mac to macOS Sequoia 15.4.1 and have been running into problems with DisplayLink ever since.

Prior to the update, my setup was working perfectly. However, after installing 15.4.1, external monitors connected through DisplayLink are no longer recognized. In addition, the DisplayLink Manager application either doesn't start correctly or opens without showing any attached displays.

To troubleshoot, I've already tried the following:

Rebooting my Mac and docking station.
Installing the latest release of DisplayLink Manager.
Removing and re-adding all required permissions in Privacy & Security.
Verifying that Screen Recording, Accessibility, and Input Monitoring are enabled.
Disconnecting and reconnecting all DisplayLink devices.

Unfortunately, none of these steps have resolved the issue.

At this point, I'm wondering if the 5 letter words Sequoia 15.4.1 update introduced a compatibility problem affecting DisplayLink drivers or changed the way macOS handles the necessary permissions.

Has anyone else experienced similar behavior after upgrading? If so, were you able to find a workaround? I'm also interested in knowing whether Synaptics/DisplayLink has acknowledged the issue or if an updated or beta version of the software is available.

Any information or suggestions would be much appreciated.

Thanks!
