How to Fix Microsoft OneNote Crashing and Freezing on Mac
Question details
The user is experiencing repeated freezing and crashing when attempting to open Microsoft OneNote on macOS.
- Product
- Microsoft OneNote
- Device & OS
- macOS Sonoma 14.5
- Scenario
- Opening and attempting to use Microsoft OneNote for note-taking on a Mac.
- Observed behavior
- OneNote becomes unresponsive immediately upon launch, showing a spinning cursor before eventually freezing completely or crashing.
Before proceeding, ensure you have backed up any unsynchronized local notebooks to prevent data loss when clearing caches or removing application folders.
Start Mac in Safe Mode and Update OneNote
Booting into Safe Mode can clear problematic system caches and help isolate software conflicts causing OneNote to freeze.
Click the Apple menu in the top left corner of your screen and select 'Shut Down' to completely power off your device.
For Apple Silicon: Press and hold the power button until 'Loading startup options' appears, select your volume, hold the Shift key, and click 'Continue in Safe Mode'. For Intel Mac: Turn on your Mac and immediately press and hold the Shift key until the login window appears.
While in Safe Mode, open the Mac App Store or Microsoft AutoUpdate tool to check for the latest versions of OneNote. Install any available updates.
Restart your Mac without holding any keys and attempt to open OneNote again to see if the issue is resolved.
Clean Reinstall with the Standalone Version
If updating does not resolve the issue, manually removing OneNote application files and reinstalling the standalone package from Microsoft can fix deep-seated corruption.
Try WPS Office for a Stable Mac Productivity Experience
If Microsoft Office applications continue to freeze or crash on your Mac, consider switching to WPS Office. It provides a lightweight, highly compatible suite for Word, Excel, and PowerPoint documents without the heavy system resource usage.
- 1. Download WPS Office: Visit the official WPS website and download the Mac version of WPS Office.
- 2. Install the Application: Open the downloaded package and drag the WPS Office icon into your Applications folder.
- 3. Open Your Files: Launch WPS Office and directly open your existing Microsoft Office documents to continue your work without missing a beat.
Frequently Asked Questions
Why does OneNote freeze and show a spinning cursor on macOS Sonoma?
This is often caused by corrupted local cache files, compatibility bugs with recent macOS updates like Sonoma, or conflicts with other background applications running on the Mac.
Will I lose my notes if I uninstall OneNote on my Mac?
Notes that are fully synced to OneDrive will not be lost. However, any recent offline changes or notes stored purely in local cache folders will be deleted if you clear the OneNote containers during uninstallation.
Can I use the web version of OneNote while my Mac app is crashing?
Yes, as a temporary workaround, you can log into OneNote.com via a web browser to access, edit, and sync your notes until the desktop application issue is resolved.
