Starting as a service
The OS X lmadmin installer does not configure the server to start automatically. Check the [install_dir]/examples/service/ directory for a sample startup script or [install_dir]/examples/launchd/ for a launchd example plist.
For the sample plist file to work, the UserName and GroupName key values need to be changed from "nobody" to a production UserName and GroupName.
For macOS earlier than 10.13, plist files should be placed in /System/Library/LaunchDaemons rather than in /System/Library/LaunchAgents. The naming convention for plist files is com.apple.filename.plist.
For macOS 10.13 or later, either location works, and there are no restrictions for plist file naming.
