> It would be nice to be able to use my iPhone or my iPad to remote control roon on the MacBook Pro (which is of course where my roon core is). Can this be done? I can explore this online sometime and plan to download roon to my iOS devices to “play around”.

Yes, absolutely.

You’ll need to leave the MacBook Pro fired up and with Roon running on it, but since it’s both your Core and your Client, there’s nothing else you need to do there.

Then you can just download the Roon app for iOS and as long as your phone/tablet is on the same WiFi network that can reach your laptop, it’ll just work.

At most, you’ll have to select the “Arche” you have configured on your MacBook Pro as the output the iOS device is to control output for. But that’s remembered once set.
