Dear Support Team,

I am encountering a critical issue where DisplayLink Manager does not recognize my DisplayLink device under the following environment:

Mac: MacBook Air (M3, Apple Silicon)
OS: macOS Tahoe 26.3
DisplayLink Manager: Version 15.0.0 (build 22)
Device: Anker 564 USB-C Dock (DisplayLink-enabled)
DisplayLink Manager continuously displays:
"Please connect your DisplayLink device"

However, the Anker 564 dock is physically connected and is clearly recognized by macOS at the hardware level.
In System Information → USB, the device appears correctly.
This confirms that macOS detects the USB device, but DisplayLink Manager fails to bind to it.

During troubleshooting, I noticed that the DisplayLink system extension does not appear to be properly registered.
When executing:

systemextensionsctl list

the DisplayLink extension is not listed at all.

I have already:
Enabled DisplayLink in Login Items
Enabled and approved all required system extensions in System Settings
Completely uninstalled and reinstalled DisplayLink Manager
Rebooted multiple times
Despite these steps, the system extension never registers.

Given that:
The hardware (Anker 564) is detected by macOS
The system extension is not registered
DisplayLink Manager cannot attach to the device

I suspect either a compatibility issue with macOS Tahoe 26.3 or a problem with the installer failing to properly register the system extension on Apple Silicon (M3).

Could you please clarify:
Whether DisplayLink Manager 15.0.0 (build 22) officially supports macOS Tahoe 26.3
Whether there are known compatibility issues with the Anker 564 on M3 devices
How to manually register or force-load the DisplayLink system extension
Whether a beta or patched version is available

For your reference, I have also attached the collected diagnostic logs to this email.


This system is part of my daily workflow, so I would greatly appreciate your guidance.

Best regards,
