System Information
Operating system: macOS Sierra 10.12.6
Graphics card: AMD FirePro D500 3072 MB

Blender Version
Broken: 2.80 (2.80 2018-11-28, Blender Foundation)
Worked: (optional)

Short description of error

Attempted to use dynamic paint with the ocean modifier to simulate an object passing through water.

Exact steps for others to reproduce the error

I essentially followed these tutorials respectively: https:*www.youtube.com/watch?v=XvKQrXMypsM , https:*www.youtube.com/watch?v=smArCTzxGpE

The crash occurs after I've constrained the object to a float plane (using shrinkwrap), and proceeded to apply dynamic paint properties to the ocean (as canvas) and the object (as brush), in this case a sphere.

It crashes at different stages of this process but usually does so when I attempt to tweak settings in one of the dynamic paint objects. For example it just crashed on me when I tried to activate antialiasing on the canvas. I have mainly worked in Evee, however I have experienced trouble in Cycles as well.

Further more, dynamic paint has trouble painting deformations correctly in animation tests. I think it may be due to cache errors, but I haven't figured out how to clear or reset cache yet.

It may be worth noting I have not applied any modifiers to any objects yet.

Here is my Apple crash report:

Based on the default startup or an attached .blend file (as simple as possible).
