Apple OSes being so amazingly simple, approachable and cleverly designed with a lot of attention paid to detail

That was the Mac in the 1990s. It was designed for, and highly usable with, a one-button mouse. It didn't have hidden context menus or obscure keyboard shortcuts. Everything was visible in the menu bar and discoverable. The Finder was spatially aware with a high degree of persistence that allowed you to develop muscle memory for where icons would appear onscreen every time you opened a folder.

There was almost nothing hidden or lurking in the background, unlike today (my modern Mac system has 500 running processes right now, despite having only 15 applications open). We've had decades of feature creep since the classic Mac OS, which has made modern Macs extremely hard to use (relatively speaking).
