Sure. I don't keep a running list of this (and I feel like I've seen some, but can't find them now) so it's a little off the cuff... - Scrollbars not appearing until you attempt scrolling, so no indication that there is more content to scroll to. If you mouse-wheel scroll, then try to move over to click and drag, sometimes the scrollbar disappears before you can grab it. Yes, you can change this default, but... it's the default. Good examples: Dock & Menu Bar System Preferences sidebar, Spotlight results, Finder windows in list view. - Having to hover over the more inner portion of a notification to get its close button to appear. - Unintuitive Finder toolbar buttons for changing types of view, grouping, and 'More...'. Years on I still click the wrong ones routinely. - Try searching your own music instead of Apple Music in the Music app. And then do it again. You are fighting the system to access your own content. Here's an example of something that to date still is adhered to pretty well: having dialogs with OK/Cancel/possibly other interactions be ordered such that OK is to the right and the default, non-destructive action is the one that is both visually highlighted and resounds to the Return key. And Cancel responds to the Esc key. If you use another system where you literally have to pause for even a split-second and figure out which button is tied to which key action and whether you are going to lose some work — or read the informative text to parse it out — it drives you batty. Have a browse over https://developer.apple.com/design/human-interface-guidelines/components/menus-and-actions/buttons https://developer.apple.com/design/human-interface-guideline... to see the sorts of things I'm talking about. There are countless little interactions now that, if you've only used other computing systems, just feel like the things you need to do to accomplish tasks. Often they are "intuitive" to pro computer users because those users have gotten used to thinking how the computer wants them to think. But, if you've ever used a Mac thing done well, each use is a delight. Sometimes you can almost reflexively use a new interface and be delighted that the right thing just happened. If you then experience the sorts of degradations that have been happening over recent years, it's a double punch: one, a tedious annoyance and two, a reminder that it used to be — and can be — different.
