Can''t Connect Remote to Core - MacMini High Sierra 10.13

I’m trying to connect my MacMini (mid 2011) running High Sierra 10.13.6 using the Roon app. When I try and connect I see this on the main screen (see attached). Can I no longer access Roon 2.0 on my MacMini because it’s running an old version of MacOS? My Mid-2011 machine isn’t upgradeable so if so, that would really suck.

Please read to the thread linked below (might contain workaround you can probably use):

Got it @BlackJack so basically with Roon Core 2.0 my older MacMini has rendered obsolete. Oh well.
