How to Fix Custom Word Theme Fonts and Colors Not Loading on Mac
Product
Microsoft Word
Device & OS
macOS Ventura
Scenario
Attempting to apply a customized document theme (.thmx file) to a Word document on a Mac.
Observed behavior
The custom theme fails to load properly, and the specified custom fonts and colors do not appear in the document, despite being installed.
Before you start

Before troubleshooting, ensure that all custom fonts associated with your theme are properly installed and validated in the macOS Font Book, and that you have completely restarted Microsoft Word.

Solution 1Recommended

Manually Browse and Load the Custom Theme

Force Word to recognize and apply the custom theme by locating the .thmx file directly through the Design tab.

Sometimes Microsoft Word for Mac fails to automatically detect custom themes placed in the default templates folder. Manually browsing for the file forces the application to load the specific color and font parameters.

1
Open the Design Tab

Launch Microsoft Word, open your document, and navigate to the 'Design' tab on the top ribbon.

2
Browse for Themes

Click on the 'Themes' button on the far left. From the dropdown menu, select 'Browse for Themes'.

3
Load the Theme File

Navigate to the location where your custom .thmx file is saved, select it, and click 'Open'. The theme should now load and appear under the 'Custom' section of the Themes menu.

Manually Browse and Load the Custom Theme
Verification: Once properly loaded, your custom colors will appear in the 'Colors' palette and your custom fonts in the 'Fonts' dropdown within the Design tab.

Frequently Asked Questions

Why are my custom fonts not showing up in Word for Mac?

Custom fonts may not show up if they are not installed properly in the macOS Font Book, if there is a font cache corruption, or if the fonts were installed only for a specific user rather than system-wide. Try validating the fonts in Font Book and restarting your Mac.

Where are Word themes stored on a Mac?

By default, custom themes in Word for Mac are usually saved in the hidden User Library folder under: ~/Library/Group Containers/UBF8T346G9.Office/User Content/Themes.

Can I use a .thmx theme file created on Windows in Word for Mac?

Yes, .thmx files are fully cross-platform. However, if your theme relies on custom fonts, you must ensure those exact fonts are manually installed on the Mac, as they are not embedded directly into the theme file.
