Do I need to install Revoscan background service?

When installing Revoscan 5 on MacOS there is the option to install service and plist. What does the rcpservice do and can I use Revoscan without installing the background service?

I usually do not install the Internet access because I don’t use any of it , but it is helpful to check if new versions are available .

I am not on Mac , but did you tried to run it without the background services installed ?
