Help on a mac mini initial set up

rohbob · March 31, 2021, 10:58pm

I have a late 2014 Mac Mini 8gig ram / 500 gig ssd. I wiped it to use as a music server exclusively.
I have downloaded a trial version of Audirvana and it is up and running.
I will run an AudioQuest Carbon USB to a Benchmark 3 HGC DAC/ Preamp and from there to a Purifi based class D amp. I currently have a Bluesound node 2i running through the Benchmark via digital coax and results are very good.
I wanted to run my iTunes through the Audirvana to optimize my cd collection. My collection is loaded at Apple Lossless.
I am not sure how to best set up my Mac Mini and the audirvana to do this. I have read other threads but I am still unsure. I am a novice at understanding the workings of the mac. I have looked into the midi set up but do not understand it and how to best set it up.
anyway ----- any help from a veteran out there would be appreciated.
Regards, Bob in Puyallup WA

Hello @rohbob,

Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message
