**System Information**
macOS High Sierra, 3.1 GHz Intel Core i5, 8 GB 2133 MHz LPDDR3, Intel Iris Plus Graphics 650 1536 MB
**Blender Version**
Broken: (version 2.79)
**Short description of error**
Whenever I try playing back my animation via the play button on the timeline, blender crashes almost immediately. This first occurred when rendering particles, but now I realize **it occurs every time**, no matter what seems to be on screen or how many objects and particles have been deleted or remain invisible. For some reason, I can still render the animation, but what I want to do is watch it in my viewport via the material, solid, wireframe, or any view without it immediately crashing. This has never happened to me before. I don't know if it is because there are too many objects in too many different layers or what.
**Exact steps for others to reproduce the error**
To reproduce this error, simply open the blend file and try playing the animation with alt + a or move to different frames on the timeline.
