Inspecting Yosemite's Icons
I want to focus on my favorite visual update in Yosemite — the dock icons. Before Yosemite, Apple maintained a system for icon design through a checklist of mostly unstated and understood guidelines paired with a few specific recommendations in the Human Interface Guidelines (HIG). With Yosemite, that system becomes more consistent, and regular, yet the HIG remains silent on the specifics.
Great in-depth analysis of icons in Yosemite. I don’t use the dock at all, but most people seem to. Saving this one for when I'm ready to ship my first OS X app.
