I've been experiencing loads of crashing while rendering lately, and after doing some testing I've finally isolated it to the GPU rendering. As soon as I change to that from CPU, blender goes down. This is odd, because I did a whole project (cgmastersnet Corvette course) with it on and had zero crashes. I have not updated Blender since then.
I found a thread about this on blender.org -> https://developer.blender.org/T53945
They seem to be saying it could be an issue with MacOS High Sierra (I am not running High Sierra, I am running Mojave 10.14.) This is my system:
Model Name: iMac Model Identifier: iMac14,2 Processor Name: Intel Core i5 Processor Speed: 3.2 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 32 GB Boot ROM Version: IM142.0130.B00 SMC Version (system): 2.15f7 Graphics card: GeForce GT 755M
And this is my Blender
2.79 - 2017-9-11
I'm wondering if others have solved this issue. I'm confused on what might have changed (other than the project - which is far simpler than a corvette).
I tried removing any recent add-ons I have used in the past few weeks, saved prefs and restarted, but the crash still happens.
Not sure what other info I can provide, please let me know. For now seems I am stuck with CPU rendering, which is a bummer.
