I’ve made mistakes in the past with incompatible devices
I understand that the Roon app needs iOS 11 as a minimum which is fine however my question is what are the minimum requirements for the core with regard to iOS if I were to use a Mac Mini
I, and many more like me, are running a Roon Core on a “vintage” Mac mini with excellent results. I bought a used 2012 model with16 GB of RAM and stripped most everything off the device that was not Roon. It plays great, including my 5.1 files through HDMI. Works as well sonically as a Nucleus, but does not require a hardwired internet. Mine runs from a Eero mesh with a short Cat 5 from the mesh pod to the Mac mini.
