You are right in saying that discoverability has suffered much, by hiding scrollbar and similar changes. Also, you need to move the mouse precisely to a particular spot to re-enable the scrollbars, there is little wiggle room, which may may things harder for handicapped people, older users, or people on the move (e.g. me on a train).

Yeah, e.g. when you have a very short scrollbar and had to guess where it is for more than 5 seconds...I'm kinda grow past that hype, nada, going back to Winux.

It is SUCH a pity that they have extraordinary hardware (even with the price point I'd still consider it a bargin, especially for the air/mini)...

Or just the way the menus are on apps. Some app implement their own file/edit/view menus at the top of the app, then some will use the apple version at the top of the OS. If you plug in a TV to use as a monitor and cannot adjust the aspect ratio you're forced to blindly activate these menus as they're clipped from the screen.

MacOS folder navigation is a complete pain too, sometimes you see the list of OS folders, sometimes you see only the folder you opened in finder. If the menu is clipped due to the above aspect ratio problem, good luck getting to your home folder... No functionality to easily open a folder in terminal. Lots of basics just counter-intuitive.

Yeah, I found it not easy to go up one level in finder. Actually I had to Google when I tried first time. The way that MacOS wants to conceal information from the users is just insane. I don't know how it is justified. Nevertheless it has a good number of ardent fans.
