Fix Microsoft Word and OneNote Cursor Bouncing on macOS Sonoma
Question details
Users are experiencing erratic cursor movements in OneNote and sudden page bouncing or scrolling in Word while typing after a macOS Sonoma system update.

- Product
- Microsoft Word and OneNote
- Device & OS
- macOS Sonoma
- Scenario
- Typing and editing documents or notes after updating the Mac operating system to macOS Sonoma.
- Observed behavior
- The cursor randomly jumps in OneNote, and pages unexpectedly bounce or scroll in Word. Reinstalling the Microsoft 365 applications does not resolve these glitches.
Ensure your Mac is connected to a stable internet network and save all open documents before checking for system updates or creating new user profiles.
Update macOS and Microsoft 365 Applications
Software incompatibility between older Office versions and the new macOS Sonoma update is a primary cause of visual glitches. Updating both patches known bugs.
Microsoft and Apple frequently release patches to address compatibility issues shortly after major OS updates. Keeping both environments updated is the most effective way to resolve typing glitches.
Click the Apple menu, go to System Settings > General > Software Update. If an update for macOS Sonoma is available, click 'Update Now'.
Open Microsoft Word or OneNote. Click on 'Help' in the top menu bar, then select 'Check for Updates'. Let the Microsoft AutoUpdate tool install any pending patches.
Once both updates are complete, restart your computer and open Word or OneNote to verify if the cursor bouncing issue is resolved.

Test Applications in a New macOS User Profile
Creating a new user profile helps determine if the erratic cursor movement is caused by a corrupted user cache or account-specific settings.
Report the Issue to Microsoft and Apple
If updates and profile testing do not work, reporting the bug directly provides developers with the diagnostic data needed for a permanent fix.

Frequently Asked Questions
Why does my Word page bounce when typing on macOS Sonoma?
This is a known software compatibility glitch between the macOS Sonoma system framework and certain builds of Microsoft 365, causing the interface to miscalculate the cursor's position and scroll erratically.
Will reinstalling Microsoft Office fix the macOS Sonoma cursor issue?
Typically, reinstalling the applications does not resolve this specific issue because it stems from OS-level compatibility bugs or user-profile corruption, rather than missing or damaged application files.
How do I know if the problem is just with my Mac user profile?
You can isolate the issue by creating a new Mac user account in System Settings > Users & Groups. If Word and OneNote work perfectly in the new account, your original user profile's preferences or cache files are causing the conflict.
