Good news!
I didn't try on the Mac Pro / RAID / Mid-2010 yet but...
Everything worked with Linux Lite 5.0 on a Mac Pro Early-2009 (no-RAID and no-Wi-Fi).
** I don't know if I'll INSTALL though, MacOS works and don't want to mess with it. Stuck on Sierra though.
No fiddling, Live worked straight-up!
Was surprise a bit, this Mac (and maybe others?) have really good audio quality.
Almost makes me want to keep it, lol!
I'll check the Mac Mini and more recent Mac Pro laterz.
