Question details
The user needs to stop PowerPoint for the web from repeatedly crashing and displaying a gray screen with a sad-face icon.
- Product
- PowerPoint for the Web
- Device & OS
- macOS (2024 MacBook Pro, M2 Max)
- Scenario
- Editing or viewing presentation files online using Chromium-based web browsers.
- Observed behavior
- The web application frequently crashes across multiple files and browsers, resulting in a gray screen displaying a sad-face icon.
Before modifying your browser settings, verify your internet connection and try to download a local copy of your presentation to prevent any data loss.
Clear Browser Cache and Disable Extensions
Resolves browser conflicts caused by corrupted cached data or incompatible browser extensions.
A common cause of web application crashes in Chromium-based browsers is a memory leak or conflict triggered by third-party extensions or outdated cache files.
Launch your browser and open an Incognito or Private Browsing window. Log in to Microsoft 365 and open your presentation to see if it still crashes.
If the presentation works in Private mode, go to your browser's extension manager and disable all extensions. Re-enable them one by one to identify the one causing the crash.
Navigate to your browser's settings, locate the privacy or history section, and clear your browsing data, specifically cached images, files, and site cookies.
Try Alternative Web Browsers
Switching browsers can bypass specific rendering bugs present in certain Chromium builds on macOS.
Update macOS and Report the Issue
Ensures your system has the latest bug fixes and helps escalate persistent compatibility issues to Microsoft.

Frequently Asked Questions
Why does PowerPoint for the web show a sad-face icon on my Mac?
The sad-face icon typically indicates that the web page crashed due to a browser memory limit being exceeded, an incompatible browser extension, or a rendering bug specific to Chromium browsers running on macOS.
Does file size cause PowerPoint for the web to crash?
While exceptionally large files with heavy multimedia can strain browser memory, users report this specific crash can occur with files of all sizes. It is often related to the browser environment and memory management rather than the file itself.
Are there browsers that work better with Microsoft 365 web apps on Mac?
Microsoft Edge is specifically optimized for Microsoft 365 web apps, even on macOS. Mozilla Firefox is also a strong alternative if you are experiencing persistent issues with Chromium-based browsers like Google Chrome.
How can I view my presentation if the web version keeps crashing?
You can download the presentation file directly to your MacBook and open it using a stable desktop application like WPS Office, which natively supports PPT and PPTX formats without relying on a web browser.
