If I assign an eGPU as a single rendering device for previews it fails with blank viewport and "ERROR | Check log for details"
Strangly enough, using both internal pro 560 and an eGPU works.
System:
Macbook pro 2017, amd pro 560 (with 1 egpu Vega 64 in Razer Core X)
macos mojave 10.14
blender 2.79b
RPR 1.7.231
below is part of log:
