Mac OS DisplayLink Stopped Working

Hello,

Could you please check the following.

1. Connect your Plugable adapter to your Mac.
2. If macOS prompts to "Allow accessory to connect?" click "Allow".
3. Choose "About this Mac" from the Apple menu on the top left corner of your main screen.
4. Click on "More Info...".
5. Click on "System Report…".
6. The System Information application will open.
7. Select the USB information from the Hardware category

In my case I can see the adapter listed:


In case it isn't visible, I would first make sure with local IT you are still allowed to connect USB accessories to your Mac.

Regards,
Szymon
