Question details

The user is unable to open a OneNote package file received from another computer on their new MacBook.

Product
Microsoft OneNote
Device & OS
macOS
Scenario
Attempting to access a OneNote file that was created on a Windows computer and transferred to a Mac.
Observed behavior
The OneNote file fails to open because OneNote for Mac does not natively support local OneNote package (.onepkg) files created by Windows versions.
Before you start

Ensure you have an active internet connection and are signed into your Microsoft account, as resolving this compatibility issue requires using cloud services like OneDrive.

Solution 1Recommended

Share the Notebook via OneDrive

This is the most reliable method for accessing Windows OneNote files on a Mac. It requires the sender to host the file on their OneDrive and share it with you.

Since OneNote for Mac relies entirely on cloud-based notebooks, local Windows package files cannot be imported directly. The sender must upload the notebook to the cloud first.

1
Ask the sender to open the notebook

Have the original sender open the OneNote file using their desktop version of OneNote on Windows.

2
Share to OneDrive

Instruct the sender to click 'File' > 'Share' from the top menu, then upload the notebook to their OneDrive account.

3
Send a sharing link

Once uploaded, the sender should generate a sharing link or send an email invitation directly to your email address.

4
Open on your Mac

Click the shared link on your MacBook to open the notebook in OneNote for Web. Finally, click 'Open in Desktop App' in the top ribbon to sync it to your local OneNote for Mac application.

Syncing Complete: Once synced, the notebook will remain accessible in your Mac's OneNote app as long as the owner continues to share it.

Frequently Asked Questions

Why won't my .onepkg file open on my Mac?

The .onepkg file format is a compressed local package file exclusive to the Windows version of OneNote. OneNote for Mac does not support reading local notebook files and relies entirely on notebooks hosted in the cloud via OneDrive or SharePoint.

Can I convert a Windows OneNote file to Mac format myself?

You cannot directly convert the file on a Mac. The conversion requires opening the file on a Windows PC with the OneNote desktop application installed, uploading it to OneDrive, and then syncing it to your Mac.

Where are OneNote files stored on a MacBook?

Unlike Windows, which allows you to save OneNote files in your Documents folder, OneNote for Mac stores notebooks in a hidden internal cache directory. Your actual notebooks are stored online in your OneDrive account.

Can I view OneNote files on my Mac offline?

Yes, but only if the notebook was previously synced to your Mac via OneDrive while you were online. You cannot open a locally transferred OneNote file offline if it hasn't been synced through your cloud account first.
