About ONEPKG
OneNote on Windows exports a notebook as a .onepkg: every section's .one file and the .onetoc2 that lists them, in their folders, packed into one Windows cabinet file, which OneNote unpacks into a new notebook when it opens one.
People get them as a notebook sent by email or handed out in a course, and from old backups. OneNote for Mac, phones and the web can't open them, and OneNote on Windows asks where to unpack the notebook before it shows a page.
Filepeek opens the package as a folder in the file list, its section groups as folders, and each section you pick opens as its pages, with their text, tables, pictures and the files attached to them, which never run. Save as ZIP or Extract all saves the sections as files.

Questions
How do I open a .onepkg on a Mac?
Drop it on this page. Its sections open in the file list, and each opens as its pages when you pick it. OneNote for Mac can't open a .onepkg.
Can I get the sections out?
Yes. Choose Export, then Save as ZIP or Extract all, and every section is saved as a .one file, in its folders, that OneNote opens.
