One Note Mac how to display all notebooks?

I'm going to assume this won't ever be implemented.

More important than treating this as a feature request is the fact that Microsoft's documentation is wrong! I just wasted 10-15 minutes trying to get this to work while I was following the "Getting Started with OneNote" tutorial in the OneNote for Teachers page. And this doesn't even count the time I wasted and will waste going through the parts of a tutorial that are completely irrelevant for my version of the app and that are likely to be just confusing!

If something in an app only works on certain platforms, then it should not be mentioned in any documentation, much less an introductory tutorial, intended for all platforms. In the worst case, there should be a caveat stating explicitly that the "feature is not present on the following platforms: ....."

I don't know what school your technical documentation people went to, but I learned this basic rule about documenting software during my first two years in engineering school. It's especially egregious for documentation for an app claiming to improve "productivity" to make this elementary yet fundamental mistake.

Grade for the tutorial thus far, D-  !

Please fix all appropriate documentation, instructional videos, etc. accordingly.

P.S. OMG! I just started the second tutorial in the series, and it instructs the viewer to pin search results. But on my Mac's version of ON 2016 there's no obvious way to pin search results.

Let me guess: the absence of a pin is due to the general absence of pinning on Macs, but discovering this is left as an unstated exercise for the viewer. It's sort of like waking up and finding oneself in a black hole but not knowing what a black hole is. Or maybe, like waking up as a bug but never learning what a bug is. Figure out why everyone around you speaks French but you can't even conceive of language.

P.P.S. and OMG! 2. I'm beginning to feel like a Hindu invited to an Xmas party at a steakhouse; this place is definitely not for people like me. The tutorial not only talks about pinning the search results, it also shows searching for changes by individual authors. But the screen in the tutorial shows a 7-item menu (File, Home, Insert, Draw, History, Review, View), but my poor Mac only has 3 (Home, Insert, and View), with more-but-still-different menu items in the app's menu bar. I have absolutely no way of knowing if this is yet another feature only for true believers (i.e., people who accept the one true religion and use a certain platform) or if I'm doing something wrong.

Either way, this demonstrates how destructive documentation like this is. Once users discover all the instructions don't apply to them but the instructions don't say which ones do and don't apply, then the instructions become worse than useless. The users will try to do things that are impossible on their platforms and just waste their time; they will not know the correct way to do certain things on their platform; and they can never be sure if the problems they run into are because they were not doing things properly or because the instructions don't pertain to them.

P.P.P.S. I stumbled into the tutorials on the OneNote for Teachers page. The first tutorial talks about how you can use OneNote on any platform. But then it goes on to describe things that only work on Windows without ever saying what's Windows-only. After scanning other comments in this thread, I realize I've seen just the tip of the iceberg. If you can't write the app so that it's more or less identical across platforms, then at least get all that awful, misleading documentation off the web!

What a disgraceful waste of time!

Yes, I also would like to have this feature in the mac version of OneNote

Do you mean you want to see the full list of notebooks in a pinned view?  

Good feedback and something we can look into in a future update...do other people want this too?  Thanks for the feedback and please keep it coming!

Yes, definitely!  OneNote for Mac is a great product, but with a lot of notebooks this is a must have IMHO.
