That mini is way under spec so you will maybe not have a great roon experience as it will struggle to get running importing and analyzing your library.
I figured it out. It was user error on my part. It became a matter of where the cursor was on the Roon icon. In fact it aligned to the label under theicon, rather than on the icon itself. Once the cursor aligns to show the “+” sign I was able to drag it to the applications folder icon…I feel pretty dumb, but lesson learned.
Just a note re the specs, you will want an SSD in there as the OS boot drive at the very least. It will struggle for hours maybe days or weeks with your library depending on the number of local tracks to import and analyse. Plus searching for this might be slow.
Roon is a server based database engine and does require some horsepower to run ideally.
Mr Fix It is correct, this is a viable solution as a Roon Server but it is “below the low end” of the performance spectrum recommended.
I have measured one of these and it works just fine but can take some time to build the library.
(And, an SSD is crucial!)
