The user needs to resolve an issue where OneNote for Mac repeatedly crashes after attempting to move a section between notebooks.

How to Fix OneNote for Mac Crashes After Moving a Section

Product: Microsoft OneNote
Device & OS: macOS
Scenario: Moving a section from one notebook to another triggers a fatal application crash.
Observed behavior: OneNote unexpectedly quits and generates EXC_CRASH or SIGABRT error logs immediately following the section move.

Before you start

Before attempting any fixes, log into OneNote for the web to ensure all your recent notes and notebook changes have successfully synchronized to the cloud to prevent data loss.

Solution 1Recommended

Clear the OneNote Container Folder

Removing the Microsoft OneNote container folder forces the app to rebuild corrupted local cache files that cause sync crashes.

macOS stores application cache and configuration files in a specific Container folder. If these files become corrupted during a sync or a section move, it can trigger continuous EXC_CRASH errors. Moving this folder to the desktop is a safe way to reset the app's local state without affecting your cloud data.

Quit the Application

Ensure OneNote is completely closed. If it is unresponsive, press Command + Option + Esc to Force Quit the app.

Navigate to the Containers Folder

Open Finder, click on 'Go' in the top menu bar, select 'Go to Folder' (or press Command + Shift + G), type '~/Library/Containers/' and press Return.

Move the OneNote Folder

Scroll to find the folder named 'Microsoft OneNote'. Click and drag this folder to your Mac's desktop.

Restart and Test

Restart your Mac, then reopen OneNote. The app will generate a fresh container folder. Check if moving a section still causes a crash.

Safe Data Recovery: If the app works perfectly after this, you can safely delete the 'Microsoft OneNote' folder from your desktop.

Solution 2

Reinstall OneNote

If clearing the cache does not work, a clean installation replaces missing or damaged application files.

Solution 3

Test Under a New Mac User Profile

Creating a new user profile helps determine if the EXC_CRASH is caused by system-wide issues or specific user account permissions.

Frequently Asked Questions

Why does OneNote throw an EXC_CRASH or SIGABRT error on my Mac?

These are standard macOS error codes indicating that the application encountered a fatal memory or sync conflict. In OneNote, this frequently happens if local cache files become corrupted when attempting to transfer large sections of data between notebooks.

Will I lose my notes if I move the Microsoft OneNote container folder to the desktop?

No, you will not lose your notes as long as they are fully synced to your cloud account. Moving the container simply removes local cache and temporary files, forcing OneNote to securely redownload your notebooks from the server.

How can I check if my notebooks are synced before I start troubleshooting?

You can verify your sync status by logging into OneNote for the web at onenote.com. If your most recent notes and changes are visible in the web browser, your data is securely backed up and safe for troubleshooting.
