unity2018 directional light cascade shadows artifacts

Hello, everyone! I already spent 5 hours of researching but couldn’t find a solution, perhaps someone experienced can help me.

Shadows of directional light have a huge artifacts, some kind of circles depends on the distance to the terrain. I’ve tried different shadow types, biases, playing with culling mask, other setting but without a positive result. I also created a clean new project, created terrain - the problem in still present. So it seems it is either unity2018.1.1f1 or something MacBook Pro (Retina, 13-inch, Late 2012) specific.
Thanks a lot!

UPDATE:
Unity3d Macbook pro: shadows cascades artifacts - YouTube apparently it’s it has some direct connection to shadow projection resolution. Still no luck to fix it.

@elpinguinofrio I’m not sure if you have tried this, but have you tried increasing your camera’s Near Clipping Plane to around 0.5 or possibly higher? Sometimes having it too low can cause shadow artifacts like seen in your video.

Hello, i had the same problem.
Go to Edit > Project Settings > GraphicsSettings. Find there Tier Settings uncheck Use Defaults on High (Tier 3) (or others), then uncheck Cascaded Shadows.

It’s help with this problem, but will cause other – called “square shadows”.
