How to Fix Montserrat Font Missing in PowerPoint on Mac
Question details
The user installed the custom Montserrat font (OTF and TTF), but it is not appearing as an available font option in PowerPoint.
- Product
- Microsoft PowerPoint
- Device & OS
- macOS
- Scenario
- Attempting to use a third-party Google font (Montserrat) in a PowerPoint presentation after installing the font files locally.
- Observed behavior
- The Montserrat font does not appear in the PowerPoint font dropdown list, even after updating the application and installing both OTF and TTF versions.
Ensure you have downloaded the official and latest version of the Montserrat font directly from Google Fonts, and delete any duplicate font files from your Downloads folder before proceeding.
Verify and Enable the Font via Font Book
Use the built-in macOS Font Book application to ensure Montserrat is properly installed, enabled, and free of validation errors that prevent PowerPoint from reading it.
Microsoft Office applications on Mac rely on the system's Font Book to load fonts. If a third-party font like Montserrat encounters a minor installation error or is disabled by default, it will not populate in PowerPoint's font menu.
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 the Font Book app to search for 'Montserrat'.
Select all Montserrat font weights, right-click, and choose 'Validate Font'. Resolve any corruption warnings or duplicate file errors.
If the font appears greyed out or has an 'Off' status, right-click the font family and select 'Enable'.
Completely quit PowerPoint by pressing Cmd + Q, then reopen your presentation to see if the font appears in the dropdown menu.
Report the Issue to Microsoft and Google
If local troubleshooting fails, report the bug directly to Microsoft Office support or Google, as third-party fonts can sometimes experience inherent compatibility issues.
Try WPS Office for Seamless Font Compatibility on Mac
If PowerPoint continues to struggle with reading custom third-party fonts like Montserrat, consider switching to WPS Office. It is a free, lightweight, and highly compatible alternative that natively supports standard custom fonts and Microsoft Office file formats seamlessly.
- 1. Download WPS Office: Install the free WPS Office suite for Mac from the official website.
- 2. Open your Presentation: Launch WPS Presentation and open your existing .pptx file.
- 3. Apply Montserrat: Select your text, open the font dropdown menu, and seamlessly apply the Montserrat font.
Frequently Asked Questions
Why do custom fonts like Montserrat not show up in Office for Mac?
Office for Mac relies heavily on the macOS system font cache. If this cache fails to sync immediately after installing new OTF or TTF files, or if the font has minor validation errors, it will not appear in the application's font menu.
Should I install the OTF or TTF version of Montserrat for PowerPoint?
It is generally recommended to install the TTF (TrueType Font) version for Microsoft Office applications on Mac. TTF files tend to offer better legacy compatibility and stability within PowerPoint compared to OTF files.
How do I clear the font cache on my Mac?
You can clear your Mac font cache easily by restarting your computer in Safe Mode (hold the Shift key during startup). Once the Mac boots into Safe Mode, restart it normally to rebuild the font cache.
Can I embed the Montserrat font in my PowerPoint file on Mac?
Yes, newer versions of Microsoft 365 and PowerPoint 2019+ for Mac support font embedding. Go to PowerPoint Preferences > Save, and check 'Embed fonts in the file' to ensure Montserrat displays correctly when sharing the presentation with others.
