It didn't happen when they introduced Leopard, because the new design was legitimately better than the ugly brushed aluminium look that preceeded it.

When they toned down the horrific excesses of skeumorphism (like leather textures) on macOS but still retained some skeumorphic design (e.g., buttons that look like buttons) people were pretty ok with it too. I remember some complaints that the lickable aqua buttons were gone but that wasn't really a serious complaint, just more of a "I kind of liked those gaudy buttons, sad they're gone" type of sentiment.
