Update OneNote and macOS to the Latest Version
Installing the latest software updates resolves known bugs, such as the specific performance issues identified in OneNote version 16.42.
Microsoft frequently releases patches to address memory leaks and lagging issues on macOS. Ensuring both your operating system and the OneNote application are up to date is the most effective way to eliminate version-specific freezing.
Launch OneNote, click on 'Help' in the top menu bar, and select 'Check for Updates'.
If an update is available (newer than version 16.42), click 'Update' to download and install the latest version.
Click the Apple logo in the top-left corner of your screen, select 'System Preferences', click on 'Software Update', and install any available updates for macOS Catalina.
Once all updates are installed, restart your Mac to ensure all system changes are fully applied before reopening OneNote.
Use OneNote for the Web as a Temporary Workaround
Using the browser-based version of OneNote bypasses local application glitches and allows you to continue working or teaching without interruption.

Frequently Asked Questions
Why does OneNote for Mac freeze randomly while typing?
Freezing while typing is often caused by known application bugs in specific builds (like version 16.42), background synchronization conflicts, or insufficient system memory when handling excessively large notebooks.
Does notebook size affect OneNote performance on Mac?
Yes. Extremely large notebooks containing high-resolution images, extensive PDF printouts, or heavy handwritten strokes require more memory to render and sync, which can lead to processing delays and lagging.
How can I prevent data loss when OneNote freezes?
If OneNote freezes and displays a processing indicator, wait for it to recover if possible. To prevent data loss in the future, periodically check that your sync status is up to date, and consider typing long texts in a lightweight editor before pasting them into a problematic notebook.
Will reinstalling the app fix the OneNote lagging issue?
Reinstalling OneNote can help resolve issues caused by corrupted cache files. However, if the lagging is tied to an unresolved bug in a specific version update, reinstalling the same version may not fix the problem until a new patch is released.
