Installlation of .NET runtime on macOS is covered in the Microsoft Docs.

The launch daemon

that runs the PDF service can be installed using an installation script.

The launch daemon is defined in a configuration file com.stepover.pdf-service.plist with content

com.stepover.pdf-service.plist

This configarution file has an array of <key>ProgramArguments</key>
that run the service using a path to <JAVA> and a <PATH-TO-PDF-SERVICE-JAR>.

Provide <JAVA>

Java can be installed on a MacOS with Homebrew

> brew install openjdk

Alternatively, fetch a JRE from adoptopenjdk.net or from Oracle
and extract it to the file system,
preferably to /usr/local.

Provide <PATH-TO-PDF-SERVICE-JAR>

Fetch the pdf-service-with-dependencies-jar
to the file system,
preferably to /usr/local/lib
and use that path in the ProgramArguments.

Install the service

Copy the deamon configuration file to

/Libraries/LaunchDaemons/com.stepover.pdf-service.plist

Reboot.

Alternatively, avoid rebooting using launchctl(1) as root:

> launchctl load /Libraries/LaunchDaemons/com.stepover.pdf-service.plist
> launchctl start com.stepover.pdf-service

The installation script

attached here executes the steps above using a JRE from adoptopenjdk.net for MacOS-x64:

install-pdf-service-with-AdoptOpenJDK-JRE-MacOS-x64.sh

#!/usr/bin/env sh
firstDir=`pwd`

echo "Please read https://www.stepoverinfo.net/src/Agreement/Agreement.html"
echo "Do you agree (y/n)? \c"
read answer
if [ "$answer" != "${answer#[Yy]}" ] ;then
    echo "ok"
else
    exit
fi
