OS: OSX 10.14.3
Software: Blender 2.8 Beta 21th Feb Build
ProRender version: 2.0.1 (core 1.325)
Consistent crashing regardless of scene (even default scene with a cube).
Instant crash with CPU Only
Crash after 10-15 iterations with dGPU Only
Random crash or completed render with dGPU+CPU
Terminal and logs only point to "Segmentation Fault: 11", Terminal screenshot and crash log attached to post.
Confirmed, same result here.
CPU only = insta crash
dGPU (560) = renders ok
dGPU + CPU = renders but slower and will random crash
Interactive preview always crashes within a few seconds.
MBP 15 i7 3.1 with dGPU 560 4GB macOS latest, latest Blender 2.8, latest RPR 2.0.1 macOS
I do not see the dGPU crash you mention. CPU I can reproduce
And fixed. Will be in the next upload.
