How to Fix OTF Fonts Not Appearing in PowerPoint on Mac
Question details
Users are unable to use a newly installed OpenType (OTF) font because it does not show up in Microsoft PowerPoint.

- Product
- Microsoft PowerPoint
- Device & OS
- Mac
- Scenario
- Creating or formatting a presentation that requires a specific custom OTF font.
- Observed behavior
- The installed OTF font is missing from the PowerPoint font dropdown menu, even after updating macOS and Microsoft Office.
Ensure that you have closed all Microsoft Office applications before troubleshooting your fonts to prevent file conflicts.
Validate and Enable the Font in Font Book
Use the macOS Font Book utility to ensure the OTF font is enabled and free of validation errors.
Sometimes a font installs successfully on a Mac but remains disabled by default, or it contains minor corruption errors that prevent Microsoft Office applications from recognizing it.
Press Cmd + Space to open Spotlight Search, type 'Font Book', and hit Enter to launch the application.
Use the search bar in the top right corner of Font Book to find the specific font that is missing in PowerPoint.
If the font name is grayed out, right-click on it and select 'Enable'. If it is already enabled, proceed to the next step.
Select the font, click 'File' in the top menu bar, and choose 'Validate Font'. If any errors are found, you may need to download a fresh copy of the font.
Restart your Mac to refresh the system font cache, then open PowerPoint to check if the font now appears in the dropdown list.

Test Font Compatibility on Another Mac
Verify whether the font itself is fundamentally incompatible with Office for Mac by testing it on a different machine.
Try WPS Presentation for Better Font Compatibility
If PowerPoint for Mac refuses to recognize your OTF fonts, consider switching to WPS Office. It is a highly compatible, lightweight, and free alternative that handles custom fonts beautifully while maintaining seamless format compatibility with Microsoft files.
- 1. Download WPS Office: Visit the official WPS website and download the macOS version of WPS Office.
- 2. Install the Suite: Open the downloaded installer and drag the WPS Office icon to your Applications folder.
- 3. Open Your Presentation: Launch WPS Presentation, open your existing .pptx file, and select your custom font from the text properties menu.

Frequently Asked Questions
Why does my OTF font work in Apple Keynote but not in PowerPoint?
Microsoft Office for Mac utilizes a different text rendering engine than native Apple applications like Keynote or Pages. This can cause specific OpenType (OTF) fonts with complex outlines or strict embedding restrictions to fail to load in PowerPoint, despite working perfectly in macOS native apps.
Can I convert an OTF font to TTF to make it work in PowerPoint?
Yes. Converting an OTF font to a TrueType Font (TTF) format using a reputable font converter often resolves compatibility issues with Microsoft Office on Mac. After converting, install the TTF version via Font Book and restart your computer.
How do I safely clear the font cache on my Mac?
The safest way to clear the font cache on a Mac is to restart the computer in Safe Mode. Simply hold down the Shift key while your Mac is booting up. Once you reach the login screen, restart your Mac normally. This process automatically clears out corrupted font caches.
