Fix PowerPoint Crashing When Exporting Video on M1 Mac
Question details
Microsoft PowerPoint consumes all available memory and crashes while trying to export a presentation as an MP4 or MOV video on a first-generation M1 MacBook Pro.
- Product
- Microsoft PowerPoint for Mac
- Device & OS
- macOS (M1 Mac)
- Scenario
- Exporting a presentation containing audio and multiple slides to a video format.
- Observed behavior
- PowerPoint experiences an out-of-memory condition while rendering through Metal and Core Image, causing the application to hang, log a SIG_HANG_QUIT error, and eventually crash, making macOS temporarily unusable.
Ensure your macOS is fully updated to the latest version and close all other background applications to free up maximum system memory before attempting another video export.
Report the Bug and Update via Office Insider Program
This issue is largely tied to a graphics-rendering bug in PowerPoint or macOS on M1 chips. Reporting it with the crash log and updating to beta builds can provide a patch.
Microsoft actively monitors memory leak issues on Apple Silicon. Providing the exact stack hash (such as main_oom_arm) helps their engineering team issue fixes in the beta update channel.
After PowerPoint crashes, wait for the Apple or Microsoft Error Reporting dialog box to appear. Click 'More Information' and copy the first 50 to 60 lines of the crash report.
Reopen PowerPoint, navigate to the top menu, and select 'Help' > 'Feedback'. Paste your copied crash report details into the submission form and send it.
If you have a Microsoft 365 subscription, go to 'Help' > 'Check for Updates'. Click 'Advanced', and opt into the Office Insider Beta Channel to download newer, potentially patched versions of PowerPoint.
Reduce Presentation Complexity and Export Resolution
Lowering the rendering burden by optimizing media and choosing lower export settings can sometimes allow the export process to finish before exhausting system memory.
Switch to WPS Office for Stable Presentation Workflows
If PowerPoint continues to crash due to macOS rendering bugs, consider switching to WPS Office. It is highly optimized for Mac, consumes fewer system resources, and offers stable performance for your presentations.
- 1. Download and Install: Visit the official WPS website and download the Mac version optimized for Apple Silicon.
- 2. Open Your Presentation: Launch WPS Presentation and open your existing .pptx file without losing any formatting.
- 3. Continue Working Seamlessly: Edit, play, and present your slides with stable system resource usage.
Frequently Asked Questions
Why does PowerPoint run out of memory on my M1 Mac?
This is a known issue involving memory leaks when PowerPoint attempts to render heavy graphics and audio through Apple's Metal and Core Image frameworks on some first-generation M1 models.
How do I find the crash report for PowerPoint?
When PowerPoint crashes, a dialog box will appear. Click 'More Information' to view the detailed text log. The first 50-60 lines contain the stack hash (like main_oom_arm) and error code (like SIG_HANG_QUIT) needed by developers to trace the bug.
Will reinstalling Microsoft Office fix the video export crash?
Usually, reinstalling the same stable version will not fix the issue because it is a core software rendering bug. Joining the Office Insider program to get the latest beta update is a more effective solution.
Can exporting to a different format prevent the crash?
Yes. The crash typically occurs during the heavy video rendering process required for MP4 or MOV files. Exporting your slides to PDF or a static image sequence will generally not trigger the same out-of-memory bug.
