MacOS autostart

[skillsfactory]

Hello,

I have installed the latest version of dcm4chee-arc on macOS 15 on Apple Silicon, and the only way to make it work properly is to launch it with sudo. However, I need it to start automatically at boot as a service without requiring user interaction.
How can I achieve this?
I also tried using a plist under LaunchDaemons, but even after adding

UserName
root

it does not run as a superuser.

Thank you
Luca
