Changes in DAC Presentation - Need Advice

My MacMini (and all MACs I have had) are awful. I had to buy a cheapo DELL to move my ROON CORE off the Mini. Just too many problems. I do not know how people put up with all the issues I see on Macs. 

Recently ROON had some hiccups for me. I did see 3 software updates from ROON that seemed to have fixed that for me. My music would stop periodically.  So, make sure you have updated all the ROON software to the latest and greatest bits.

I was also only using my MacMini for CORE. My issue was not sound quality. It was that ROON would have performance issues on the Mac. It would crash, stop playing, the MacMini would update the OS and then not reboot. I had to restore this machine close to a dozen times with a backup OS copy. That was also a PIA to do. Just a piece of crap software.

I am a software developer myself and I get frustrated to no end when I have to use the Mac. I am too old now to deal with stuff like this. I just need a machine that just works all the time. 

BTW - I am one of those heretics that say that by using Fibre Optical wire just before the DAC. It does not matter about the quality of the machine hosting the music server (ROON Core in my case) as long as the machine is located before the FIbre Optic cable. Fibre cannot carry analog noise.
