Fix PowerPoint Captions Turning Off After Saving on Mac
Question details
The user is experiencing an issue where PowerPoint's live captions automatically turn off after a presentation file is saved.
- Product
- Microsoft PowerPoint for Mac
- Device & OS
- macOS
- Scenario
- Saving a presentation file while the 'Always Use Subtitles' feature is enabled.
- Observed behavior
- The captions disable themselves automatically immediately after saving, requiring the user to manually toggle them back on.
Ensure you have your Microsoft 365 account credentials available, as you may need to install software updates, and save a backup copy of your presentation before troubleshooting.
Isolate the Issue Using Mac Safe Mode
Booting your Mac in Safe Mode helps determine if background programs or cache issues are interfering with PowerPoint's subtitle settings.
Safe Mode clears temporary system caches and prevents third-party software from launching at startup. If the captions stay on while in Safe Mode, a background application is likely causing the interference.
Click the Apple menu in the top-left corner of your screen and select 'Shut Down'.
Turn on your Mac and immediately press and hold the Shift key. Release the Shift key when you see the login window.
Open PowerPoint, enable the 'Always Use Subtitles' feature, and save the presentation. Check if the captions remain active after the save completes.
Update PowerPoint and Submit Feedback
If the issue persists in Safe Mode, it may be a known software bug in your specific build (e.g., version 16.87). Updating the app or reporting it helps Microsoft issue a fix.
Experience Stable Presentations with WPS Office for Mac

Frequently Asked Questions
Why do PowerPoint subtitles turn off automatically after saving?
This behavior is often caused by a software glitch or bug in specific versions of PowerPoint for Mac (such as build 16.87), where the save process incorrectly resets the user's 'Always Use Subtitles' preference.
Does Mac Safe Mode permanently fix the subtitle issue?
Not always. Safe Mode is primarily a diagnostic tool used to rule out interference from third-party apps or system caches. If the issue continues in Safe Mode, it indicates an inherent bug within the PowerPoint application itself.
Where can I report persistent bugs in PowerPoint for Mac?
You can report unresolvable bugs directly to Microsoft's development team by opening PowerPoint and navigating to 'Help' > 'Feedback' > 'Report a Problem' from the top menu bar.
Do I need an internet connection for PowerPoint captions to work?
Yes, PowerPoint's live captions and subtitles require a reliable internet connection, as the application relies on cloud-based speech recognition services to process spoken words into text in real-time.
