Fix Garbled PowerPoint Title Text on Mac (Version 16.83)
Question details
Users are experiencing an issue where PowerPoint title text boxes display garbled or unreadable characters on macOS after updating to version 16.83.
- Product
- Microsoft PowerPoint
- Device & OS
- macOS
- Scenario
- Editing or viewing presentation slides in PowerPoint for Mac after a recent software update.
- Observed behavior
- Title text boxes show garbled characters. This display error can affect a specific placeholder, a single slide, an entire file, or the whole application globally.
Determine if the issue is isolated by creating a completely new blank presentation and typing text into a title box. If the text displays normally, the problem may be restricted to a specific corrupted file.
Clear PowerPoint Cache Files from the Containers Folder
Removing outdated or corrupted cache files often resolves application-wide text display issues following a macOS or Office update.
macOS caches application data in the background to improve loading times. However, after updating to version 16.83, old cache data might conflict with the new application files, causing fonts to render as garbled text.
Ensure Microsoft PowerPoint is fully closed by right-clicking its icon in the Dock and selecting Quit, or by pressing Command + Q.
Click on Finder. From the top menu bar, select Go > Go to Folder (or press Shift + Command + G). Type ~/Library/Containers/ and press Return.
Locate the folder named 'Microsoft PowerPoint' (or 'com.microsoft.Powerpoint' on older macOS versions). Drag this folder to the Trash.
Restart your Mac, launch PowerPoint, and open your presentation to verify if the title text now displays correctly.
Reinstall Microsoft PowerPoint
If clearing the cache does not resolve the garbled text, the update installation itself might be corrupted and requires a clean reinstall.

Frequently Asked Questions
Why does my text look like garbled symbols after updating PowerPoint?
This is often caused by a conflict between the new application version (such as 16.83) and older, corrupted cache files stored in your macOS Library. It can also be related to missing or incompatible system fonts.
How do I take a screenshot on Mac to send to support?
You can capture your entire screen by pressing Shift+Command+3, or capture a specific portion by pressing Shift+Command+4. To copy the screenshot directly to your clipboard for pasting into a support chat, press Control+Shift+Command+3.
Will reinstalling PowerPoint fix file-specific corruption?
If the garbled text is isolated to a single presentation file and all new files work perfectly, reinstalling PowerPoint will likely not fix the issue. The specific file itself may be corrupted and might need to be restored from a backup or recreated.
