I thought I'd open a new thread for Mac users: Microsoft have just released an Evernote importer for Mac, available from:

https://www.onenote.com/import-evernote-to-onenote

Dang, this thing is nasty. As soon as it launched it opened Evernote and started exporting notes. Didn't bother to ask permission, tell me what it was doing, or anything. I immediately force-quit the OneNote exporter and deleted it.

Typical arrogant Microsoft software.
