In enterprise environments utilizing MDM solutions like Jamf Pro for macOS device management, software installations often occur during automated workflows such as PreStage enrollment. These installations run in a root context without an active user session. 

Currently, the DisplayLink Manager installer includes a post-installation script that attempts to launch the application using:

currentuser=$(/usr/bin/stat -f %Su /dev/console)
launchctl asuser $(/usr/bin/id -u "$currentuser") /usr/bin/open "/Applications/DisplayLink Manager.app"

This approach fails when no user is logged in, leading to installation errors in automated deployment scenarios.

Proposed Enhancement:

Modify the post-installation script to check for an active user session before attempting to launch the application. For example:

currentuser=$(/usr/bin/stat -f %Su /dev/console)
if [[ "$currentuser" != "root" && -n "$currentuser" ]]; then
launchctl asuser $(/usr/bin/id -u "$currentuser") /usr/bin/open "/Applications/DisplayLink Manager.app"
else
echo "No active user session detected; skipping application launch."
fi

Implementing this check would prevent installation failures during automated deployments and improve compatibility with MDM-managed environments.
