macOS: Screen Recording permission
macOS requires the user to permit "Screen Recording" in order for DisplayLink devices to work properly. The message is generated by the OS and the screen is not actually being recorded by DisplayLink. Approving it enables the DisplayLink driver to access the pixels it needs to render a mirrored or extended screens, and send the pixels over USB from your computer to the DisplayLink display. It does not send any data or pixels back to DisplayLink.
To grant the permission, please follow these steps:
1. Download and install the latest DisplayLink Manager.
2. After installation, you will see the following prompt to open System Settings and grant permission.
2. You will be redirected to Screen & System Audio Recording.
3. Slide the switch next to the DisplayLink Manager application.
4. When you move the slider you will see the following message. Press Quit & Reopen.
DisplayLink Manager restarts and everything is ready to go.
