Question details
Users experience freezing, lagging, or canceled changes when editing PowerPoint files stored or shared via OneDrive on macOS Sonoma.

- Product
- Microsoft PowerPoint, OneDrive
- Device & OS
- macOS Sonoma
- Scenario
- Editing and saving PowerPoint presentations synced or stored on OneDrive.

Resolve OneDrive Sync Conflicts and Update Software
Ensure you only have a single version of OneDrive running and keep macOS, Office, and OneDrive up to date to prevent conflicts.
Running multiple versions of OneDrive (such as the standalone download and the Mac App Store version simultaneously) can cause severe sync conflicts on macOS Sonoma, particularly affecting larger PowerPoint files.
Open the Activity Monitor on your Mac (via Spotlight search or Launchpad) and search for 'OneDrive' to ensure only one instance of the application is running.
If you notice multiple versions installed in your Applications folder, drag the duplicate version to the Trash to avoid ongoing sync conflicts.
Open Microsoft AutoUpdate and the Mac App Store to check for and install the latest updates for macOS Sonoma, OneDrive, and Microsoft Office.
Restart your Mac, open OneDrive, and attempt to edit the PowerPoint file again to see if the freezing issue is resolved.

Test PowerPoint in a New macOS User Profile
A corrupted user profile on macOS Sonoma can cause app-specific freezing issues. Creating a new profile helps isolate the problem.
Use WPS Office for Seamless Presentation Editing on Mac
If Microsoft PowerPoint continues to freeze on your macOS Sonoma device, try WPS Office. It provides a highly compatible, lightweight, and free alternative to manage your presentations without frustrating syncing bugs.
- 1. Download WPS Office: Visit the official WPS Office website and download the installation package designed for macOS.
- 2. Install the application: Open the downloaded file and follow the on-screen instructions to install WPS Office on your Mac.
- 3. Open your presentation: Launch WPS Presentation and open your existing .pptx files to continue editing smoothly without freeze issues.

Frequently Asked Questions
Why does only PowerPoint freeze on OneDrive, while Word and Excel work fine?
PowerPoint files often contain larger media assets, complex graphics, and animations that require more system memory and aggressive cloud syncing. A minor conflict in OneDrive's sync engine on macOS Sonoma can cause PowerPoint to freeze while handling these large data transfers, whereas simpler Word and Excel files remain unaffected.
Will I lose my presentation changes if PowerPoint freezes on my Mac?
If AutoSave was interrupted by the application freezing, you might lose your most recent unsaved changes. It is recommended to force quit the app and check the local Office AutoRecovery folder on your Mac for the most recent backup file when you relaunch PowerPoint.
How do I know if I have duplicate OneDrive apps installed on my Mac?
Go to your 'Applications' folder and look for multiple OneDrive icons. You can also open the 'Activity Monitor' and search for 'OneDrive' to check for duplicate background processes. Running the Mac App Store version alongside the standalone website download version frequently causes system conflicts.
