How to Fix Microsoft OneNote Crashing on Mac Running macOS Sonoma
Question details
The user is experiencing repeated crashes with Microsoft OneNote on a Mac running macOS Sonoma, which persist even after reinstalling the application.
- Product
- Microsoft OneNote
- Device & OS
- macOS Sonoma
- Scenario
- Opening and attempting to use Microsoft OneNote after updating the Mac operating system to macOS Sonoma.
- Observed behavior
- The OneNote application crashes repeatedly and fails to stay open, failing to be resolved by a standard application reinstallation.
Verify that your recent notes have been fully synced to OneDrive online before modifying application folders, and ensure your Mac is connected to power.
Clear the OneNote Container Folder
Removing corrupted local cache and configuration files forces the application to rebuild its settings, which is the most effective fix for persistent crashes on macOS.
macOS stores application cache and temporary settings in a hidden Containers folder. If these files become corrupted during an OS update, reinstalling the app won't fix the crash because the old configuration remains. Clearing this folder resolves the conflict.
Ensure all Microsoft Office applications, including OneNote, Word, and Excel, are completely closed.
Open Finder. On your keyboard, press Command+Shift+G to launch the 'Go to Folder' window. Type ~/Library and hit Return, then locate and open the 'Containers' folder.
Find the folder named 'Microsoft OneNote' (or 'com.microsoft.onenote'). Drag and drop this folder onto your Mac's Desktop.
Open Microsoft OneNote from your Applications folder. The app will take a moment to recreate the container folder and should now launch without crashing.
Boot into Safe Mode and Disable Add-ins
Safe Mode helps determine if background software or third-party Office add-ins are interfering with OneNote.
Update macOS and Test a New User Profile
System-level bugs in earlier versions of macOS Sonoma or a corrupted user profile can trigger application instability.
Try WPS Office for a Stable, All-in-One Experience on Mac
If Microsoft Office applications continue to crash or cause productivity issues on macOS Sonoma, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for document creation, spreadsheets, and PDF management without the heavy system load.
- 1. Download the App: Visit the official WPS Office website and download the Mac version.
- 2. Install on Mac: Open the downloaded file and drag the WPS Office icon into your Applications folder.
- 3. Start Creating: Launch WPS Office and easily open your existing documents or start new projects.
Frequently Asked Questions
Why does OneNote keep crashing specifically on macOS Sonoma?
Compatibility issues between older versions of OneNote and the updated system libraries in macOS Sonoma often trigger these crashes. Updating your macOS to version 14.4 or later usually resolves these system-level conflicts.
Will I lose my notes if I move the OneNote container folder to the desktop?
No, your notes are safely synced to your Microsoft account (OneDrive). Moving the container folder simply resets local application cache and settings. Once you relaunch the app, OneNote will rebuild this folder and sync your notebooks.
What should I do if OneNote still crashes in a new Mac user profile?
If it crashes in a completely new user profile, the issue is system-wide rather than user-specific. You may need to completely uninstall the entire Microsoft Office suite, clear all associated Library files, and perform a clean reinstallation.
