System Information
Operating system: Darwin-19.0.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon VII OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.0.68

Blender Version
Broken: version: 2.81 (sub 15), branch: master, commit date: 2019-10-14 16:46, hash: rB879d269e8769
Worked: Blender 2.8 shows same bug

Short description of error
During CPU rendering, Blender crashes when I log in or wake the display. Blender crashes also after it has finished the render.

Exact steps for others to reproduce the error
I start CPU render, Mac uses eGPU for Display. Display goes to sleep. I wake up the display, log in and blender crashes 100% times. Crash can be avoided by not using eGPU but integrated Graphic on Mac Mini, or Disable Monitor sleep function.
I have reported a bug to Apple already too

  • UPDATE 16.10. *<

I have narrowed down the cause, the crash is triggered solely by display turning off, whether automatic logging off nor screensaver makes Blender render process crash.
