- Product
- OneNote for Mac
- Device & OS
- Mac
- Scenario
- Adding new rows or columns to tables and applying global formatting settings.
- Observed behavior
- Formatting options and global language settings fail to apply correctly. Fonts automatically revert to Calibri when rows or columns are added to tables in version 16.69.
Before beginning troubleshooting, make sure your Mac is connected to the internet and check your sync status to ensure no recent notes are lost.
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.
Open your preferred web browser and navigate to OneNote for the web.
Log in with your Microsoft account credentials and open the affected notebook.
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.

Uninstall and Reinstall OneNote for Mac
If the formatting issue only happens on the local Mac app, reinstalling the application can resolve corrupted application files causing the bug.

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.
