> Yea on macOS, the scroll bar is less of a scroll bar, and more of a scroll indicator. There just isn’t any reason to click on the scroll bar if you have a trackpad.
I've seen so many web pages whose "fold line" just aligned so neatly with the end of my viewport that without the scrollbar being visible I would've just closed the page, being disappointed that it's just a meaningless hero page with no content.
Similarly, if stuff like selection boxes align just right, you simply can't see there are more options without a scrollbar. It just looks like you only have those options that are on the screen right now.
It's just plain bad UX coming from Apple.
