Solution 1Recommended

Isolate the Issue Using OneNote for the Web

Determine if the font and formatting bug is specific to your Mac application or if it affects your account globally by testing on the web version.

By using the web version of OneNote, you can bypass local application bugs. If the web version works perfectly, the issue is isolated to your local Mac installation.

1
Access OneNote Online

Open your preferred web browser and navigate to OneNote for the web.

2
Sign In and Test

Log in with your Microsoft account credentials and open the affected notebook.

3
Verify Formatting Behavior

Try adding rows or columns to a table to see if the font still automatically changes to Calibri. Check if your global font settings apply correctly here.

Isolate the Issue Using OneNote for the Web
Next Steps Based on Web Test: If the issue also occurs in OneNote for the web, further account-specific or notebook-specific troubleshooting may be required.

Frequently Asked Questions

Why does my font keep changing to Calibri in OneNote tables on Mac?

This is often caused by a software bug in specific versions of OneNote for Mac (such as 16.69) where the default font styling overrides your custom settings when the application generates new table rows or columns.

How do I change the default font in OneNote for Mac?

You can change the default font by going to 'OneNote' > 'Preferences' from the top menu bar, selecting 'Edit & View', and choosing your preferred default font and size.

Will uninstalling OneNote for Mac delete my notebooks?

No, uninstalling the application will not delete your notebooks as long as they are successfully synced to your OneDrive account before removal. They will be available once you reinstall and sign back in.
