Question

(How) is it possible to import notes from Apple Notes (Mac) to Notes (Mac oder Web)?

Answer 1

You can't import Apple Notes to Notion directly. You will need to create a shortcut in your Mac to somehow export them to a specific format or export them as PDF to then import the notes into Notion.

Maybe it is easier to copy and paste, it all depends on the number of notes you want to import and in what format you need them.
