Installing DisplayLink Manager starts with identifying the Mac's operating system version through About This Mac. Plugable's current guide demonstrates macOS Tahoe and notes that Sonoma and Sequoia follow a similar process. Download the matching application version rather than relying on an old installer already stored on the computer.

The installer presents introduction, license, and installation steps and may request the system password. Follow the remaining permission instructions for that macOS release after installation. Completing an installer alone does not establish that the application has the screen access required to generate external monitor images.
