I recently purchased a Mac Mini to use as a music server in my system. I came across the Audirvana software and decided to give it a try. There are no iTunes files (songs) on the Mac Mini hard drive and I am streaming my iTunes from cloud account to the Mac Mini. When I attempt to use the Audirvana software I get an error as says it cannot load the song. Do the ITunes song files have to be present on the Mac Mini for the software to work? I am new to Apple PC products. I have a windows (operating system Windows 7 64-bit) PC that houses all my iTunes music files.
