Arri Raw playback on 2019 MacPro

Hi,

I'm evaluating a trial of Mistika Boutique 10.2.0 on my 2019 MacPro.

Everything is working great, but I can not get Arri Raw to play back at all. This includes .ari and mxf wrapped from the Amira.  The app just sits there and I get a spinning ball until I hit stop on my tangent panel. 

I have watched the "Performance Setting Tutorial" on YouTube, but nothing I set seems to help with the Arri files.  Maybe I'm missing a setting, can anyone recommend an optimal config setting? 

These are my specs: 

2019-Mac Pro with 3.5Ghz 8-Core Intel XeonW, 

MacOS Big Sur 11.4

288GB RAM, 

Single AMD Radeon W5700X 

Directly attached TB3 SSD Raid.

FWIW, I can play back the same files in realtime on this system with other software packages , so I don't believe I have a hardware bottleneck.

Thanks in Advance!

Michael
