Checking in before I engage myself in testing High Sierra 10.13.6

Main Rig:
12-core D700 64GB 1TB nMP - RRX in sonnet, 32TB RAID, and 4K decklink via TB2 (all separate boxes and TB2 controller paths)

90% Dragon 6K R3D

Also, was the R3D "black video only" issue fixed when running High Sierra?

Thanks & Best Regards!
