Hi David,
Thank you for posting your query in our community.
Per your description, you are trying to open .one file from OneNote for Mac.
Currently, OneNote for Mac can only open files stored on the Online, and does not support opening .one and .onepkg files, which is a limitation of OneNote for Mac. Therefore, the exported OneNote notes .one and .onepkg files can only be opened in OneNote 2016 on the PC side.
Since you have .one files on your old PC, we assume that you have OneNote 2016 on your device, given this situation, we'd suggest that you could directly open these .one file from OneNote 2016 on your old PC and then create a new notebook in your account, move or copy these sections to this new notebook. Here are the steps:
- Login to OneNote 2016 with your account, and then create a new notebook with this account.
- You can directly double-click these .one files, and they will be opened from OneNote 2016 automatically.
Then these sections will show under Open Sections part.
- Then right-click a section, and click Move and select to the new notebook you created. An article for your reference: Move or copy notes between notebooks and sections (microsoft.com)
- Now you can go OneDrive Online/OneNote Online to see if these sections have been synced successfully.
Best regards,
Jazlyn
