Mac OS Neumorphic Icons

The current Big Sur Mac OS icon set is really inconsistent with no uniformity across Apple's ecosystem of platform apps.

The iconography varies from have soft drop shadows to harsh inner shadows, Indents to emboss, 3D effects to flat UI and the occasional use of skeuomorphism to make the icon appear like the object.

I've designed iMovie, Books, Music and News to demonstrate how the icons could be more uniformed.
