The HIG is utter garbage, objectively wrong on many topics and Apple never even follows every aspect of it themselves. Here's all the desktop UI research you need to know: Apple has the worst UI of any desktop OS by far. It's full of undiscoverable functionality, icon-only buttons that you have to click first to find out what they do and lacking many features for basic things like window management... But it certainly is hilarious watching people operate it, swiping furiously to find that full-screen app that they lost because there's no real maximize button and the dock is now hidden or having to use the mouse pointer to do just every operation because the keyboard acceleration sucks. Their mobile OS UI is very similarly meh, lacking options, hiding things and so-forth...the only thing really good about it is that it's more stable than Android. And actually your own ignorance has been displayed here. There's nothing about the alleged superiority of one-button mice in the HIG. Look it up.
