Question details

Users experience an application freeze with a spinning color wheel followed by a crash when attempting to save new or existing PowerPoint files on macOS.

Product: Microsoft PowerPoint
Device & OS: macOS Sequoia
Scenario: Saving or using the 'Save As' function for presentations, often in an organizational environment using OneDrive.
Observed behavior: PowerPoint hangs indefinitely with a spinning color wheel and eventually crashes during the save process, an issue also observed in Word and Excel.

Before you start

Verify that your Mac is fully updated to the latest minor release of macOS Sequoia, and attempt to save a copy of your presentation to a local folder rather than a synced cloud directory to prevent immediate data loss.

Solution 1Recommended

Force Quit OpenAndSavePanelService and Restart OneDrive

Use this temporary workaround to bypass the immediate freezing issue so you can successfully save your presentation without PowerPoint crashing.

The crashing issue on macOS Sequoia is frequently linked to a conflict between the system's file save dialog service and cloud syncing tools like Microsoft OneDrive. Terminating the background service forces macOS to launch a fresh instance.

Open Activity Monitor

Click the Launchpad icon in the Dock, type 'Activity Monitor' in the search field, and open the application.

Force quit the service

In the search bar at the top right of Activity Monitor, type 'OpenAndSavePanelService'. Select the process, click the 'X' button at the top, and choose 'Force Quit'.

Restart Microsoft OneDrive

Click the OneDrive cloud icon in the top macOS menu bar, click the gear icon (Help & Settings), and select 'Quit OneDrive'. Afterward, reopen OneDrive from your Applications folder.

Save your presentation

Return to Microsoft PowerPoint and attempt to use the 'Save' or 'Save As' function again.

Temporary Relief: This method may not provide a permanent fix. You might need to repeat these steps if the spinning wheel issue returns during future save attempts.

Solution 2

Open a Microsoft Support Ticket via Your IT Administrator

Since this issue affects multiple users across various Office applications (Word, Excel, PowerPoint) on macOS Sequoia, a formal support ticket is required for Microsoft to investigate the root cause.

Frequently Asked Questions

Why does PowerPoint show a spinning color wheel when I try to save?

This commonly happens on macOS Sequoia due to a conflict between the system's 'OpenAndSavePanelService' and cloud storage synchronization apps like Microsoft OneDrive. The application hangs while waiting for the save dialog to respond.

Does this save crashing issue affect other Office applications on Mac?

Yes, many users running macOS Sequoia have reported experiencing the exact same freezing and crashing behavior when attempting to save documents in Microsoft Word and Microsoft Excel.

Will I lose my presentation data if PowerPoint crashes?

If AutoRecover is enabled, PowerPoint may salvage your most recent changes upon reopening. However, forced crashes carry a high risk of data loss. It is recommended to apply the temporary workaround to unfreeze the app before force-quitting PowerPoint itself.

How can I avoid the spinning wheel issue entirely?

While awaiting a permanent patch from Microsoft and Apple, you can avoid this issue by using an alternative suite like WPS Office, which handles file saving reliably on macOS without triggering the OpenAndSavePanelService conflict.
