Exactly. I'm OneNote user for last 15 years or so. I got roped it in because it was free and good enough for my text notes (with image and PDF attachments).
I transitioned to MacOS 10 years back.. and lo behold, free OneNote application available there too with free cloud storage (OneDrive) and cross device sync story (mobile, Windows). Works great.
No way of avoiding cloud storage though, which is a problem for confidential information. That's why I dropped it when I moved to Mac, and the Windows version later moved to the same restriction. It's a pity: I happily paid for OneNote in the early days, and in some respects I have not found anything as good.
Oh, and one peculiar restriction: I found that there was no way to import the .one files I had brought over from Windows, even though there was at least one third party system which could do it.
