I am giving Roon a trial and *want to run Roon’s [Core, Control, and Output components all in one computer. I know this is not the optimal installation but my system has a signal computer setup.
This is the most important one if using it to output via usb DAC. https://kb.roonlabs.com/Exclusive_Mode
Not that familiar with osx though as to what else you can do.
I think those relate to library scanning which you don’t want it to do whilst playing music at the same time on the same system I guess as it will take cpu away from playback.
