Mac Security Permission
Since MacOS High Sierra 10.13, the operating system applies a stricter security policy to software like DisplayLink. As a result, the
user now has to explicitly enable DisplayLink in the Security & Privacy system preference after installation and before the
DisplayLink software is allowed to run.
At the end of the installation, the operating system should display a "System Extension Blocked after installation" warning and
ask to enable the DisplayLink extension as in the screenshot below.
If the warning is not displayed during installation choose
Security & Privacy
in
Settings
and
Allow
“System software from developer DisplayLink Corp”. This can only be done within 30
minutes of installation.
