Description of Issue

I am forced to use Roon Legacy 1.8 as my Mac supports only this.

I cannot see the Roon ARC option in the settings, maybe I must download something else other than Roon 1.8 All-in-one?

What I want to ask you is HOW to have Roon ARC enabled on my system?

Thanks for your help!

You can’t only v2 supports ARC.

Ok, thanks!
