  • PowerPoint crashing, freezing, or not responding on macOS 10.14 (especially Mojave 10.14.6)
  • Problems exporting PowerPoint presentations to video formats like MP4 on macOS 10.14
  • Performance issues – PowerPoint being very slow to launch or use on macOS 10.14
  • Compatibility issues running older versions of PowerPoint, especially PowerPoint 2011 which is 32-bit

Main causes:

  • Lack of support for older 32-bit PowerPoint versions on newer 64-bit macOS versions
  • Insufficient system resources like RAM or graphics capability


  • Update both macOS and PowerPoint to latest versions (Mojave 10.14.6 and PowerPoint 16.x)
  • Reset application preferences and caches for PowerPoint
  • Use Mac in Safe Mode to isolate issues caused by other apps
  • Increase system resources like RAM for better PowerPoint performance
  • Upgrade from older PowerPoint 2011 to newer 64-bit PowerPoint version
  • Reinstall or clean install of both macOS and PowerPoint

So in summary – ensuring the latest updates, isolating conflicts, and increasing resources can help resolve most PowerPoint issues on macOS 10.14. Switching from older 32-bit to newer 64-bit PowerPoint may be necessary if all else fails. Let me know if you need any clarification or have additional questions!
