I used to have a PPC Mac and I loved it. It did indeed “just work”. But as the os has changed over the years I felt less and less inclined to stick with Mac. These days I find a Mac way too restrictive; stuff that was doable has had the options removed. A good example was when the Apple office suite moved to the on-line shop and became free. Apple removed half the functionality from it.
On a general note, I find it a bit crap that after, (what?) 40? 50? years, the basic desktop interface has not changed much. You could argue that this means that xerox got it right first time round. Maybe. But it’s a pretty bloody inefficient way to work. These days I use i3wm on Void Linux - not needing to use the mouse so much and the lack of all that overlapping window juggling and other crap makes my life much easier
