How to Open a Windows OneNote File on a New MacBook
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.
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.
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.
Have the original sender open the OneNote file using their desktop version of OneNote on Windows.
Instruct the sender to click 'File' > 'Share' from the top menu, then upload the notebook to their OneDrive account.
Once uploaded, the sender should generate a sharing link or send an email invitation directly to your email address.
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.
Export to a Mac-Compatible Format (PDF)
If you only need to view or print the contents and do not need to actively edit the notebook, exporting the file as a PDF is a quick workaround.
Looking for a Hassle-Free Office Suite for Your Mac?

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.
