Question details
User is unable to select specific variations of the Work Sans font in PowerPoint for Mac, despite the font being successfully installed in Font Book and functioning in other applications.

- Product
- Microsoft PowerPoint for Mac
- Device & OS
- macOS
- Scenario
- Attempting to apply different font weights and variations of the Work Sans font to text in a presentation slide.
- Observed behavior
- The Work Sans font variations do not appear in the PowerPoint font dropdown menu, even though they display perfectly in macOS Font Book and other design software.
Verify that both your macOS and Microsoft Office installations are updated to their latest versions, and save any open documents before executing system terminal commands.
Rebuild the macOS Font Cache using Terminal
Clearing the system's font cache forces PowerPoint to resync its font directory with macOS, resolving issues where newly installed font variations do not appear.
Microsoft Office applications for Mac sometimes fail to update their internal font lists when new variations are installed. Rebuilding the macOS font cache via Terminal forces a complete refresh of all font directories.
Completely quit PowerPoint, Word, and Excel. Do not just close the windows; ensure the applications are fully terminated from the Dock.
Navigate to Applications > Utilities and launch the Terminal application, or search for it using Spotlight.
Type 'atsutil databases -remove' into the Terminal window and press Enter. You may be prompted to enter your administrator password.
Type 'atsutil server -shutdown' and press Enter to stop the background font service.
Type 'atsutil server -ping' and press Enter to restart the font service and regenerate the clean cache.
Reboot your macOS system to ensure all cache changes are properly applied, then reopen PowerPoint to check for the missing font variations.

Remove and Reinstall the Work Sans Font
Reinstalling the font family ensures that no corrupted font files are preventing PowerPoint from reading the variations correctly.
Try WPS Presentation for Better Font Management on Mac
If PowerPoint for Mac continues to struggle with rendering custom font variations like Work Sans, WPS Office provides a highly compatible and lightweight alternative. It natively reads macOS system fonts without syncing delays and flawlessly handles your existing presentation files.
- 1. Download and Install WPS Office: Visit the official WPS website, download the macOS installer, and move it to your Applications folder.
- 2. Open Your Presentation: Launch WPS Presentation and directly open your existing .pptx file without needing any format conversion.
- 3. Apply Custom Font Variations: Select your text, open the font dropdown menu, and easily apply any Work Sans font variation installed on your Mac.

Frequently Asked Questions
Why do fonts show up in macOS Font Book but not in PowerPoint?
Microsoft Office for Mac utilizes a sandbox environment and maintains its own font cache, which can sometimes fail to synchronize with the main macOS Font Book directory, leaving newly installed variations hidden.
Does the font file format affect compatibility with PowerPoint for Mac?
Yes. PowerPoint for Mac sometimes has difficulties parsing OpenType (.otf) font variations. If you are experiencing missing weights, try uninstalling the OTF version and installing the TrueType (.ttf) version of the font instead.
How can I prevent font synchronization issues in Office for Mac in the future?
Keep your Microsoft Office suite updated via Microsoft AutoUpdate. Frequent updates contain bug fixes for typography rendering and font synchronization that reduce the likelihood of cache failures.
