Question details
The user is unable to find the Customize Fonts option within the Slide Master view to change the default presentation font theme.

- Product
- Microsoft PowerPoint
- Device & OS
- Mac
- Scenario
- Attempting to create or apply a custom font theme to a presentation across all slide master layouts.
- Observed behavior
- The Customize Fonts option is missing in PowerPoint for Mac, preventing the user from setting a universal font theme for newly inserted text boxes, charts, and tables.
Ensure the specific font you want to use is properly installed on your macOS system via the Font Book application before attempting to apply it in PowerPoint.
Create a Custom Font Theme Using a Text Editor
Since the GUI option is exclusive to Windows, you can force PowerPoint for Mac to use your desired fonts by manually creating an XML theme file.
PowerPoint for Mac does not natively support creating custom font themes directly from the interface. However, it can read custom XML theme files if they are placed in the correct system directory. By using a plain text editor, you can script the exact font theme you need.
Launch a plain text editor on your Mac, such as TextEdit or BBEdit. If using TextEdit, ensure you switch to Make Plain Text under the Format menu.
Draft a standard Office font theme XML code, specifying your desired installed font names for the majorFont (Headings) and minorFont (Body text) tags.
Save the newly created document with an .xml extension. Move this file to the following directory on your Mac: ~/Library/Group Containers/UBF8T346G9.Office/User Content/Themes/Theme Fonts.
Restart PowerPoint, open your presentation, navigate to the Slide Master tab, click the Fonts dropdown menu, and select your newly created custom theme from the Custom list.

Change Slide Master Placeholder Fonts Manually
If you are unable to edit XML files, you can manually change the font for existing placeholders directly within the Slide Master view.
Switch to WPS Office for a Streamlined Experience
If you are frustrated by the missing features and platform inconsistencies in Microsoft Office for Mac, consider switching to WPS Office. WPS Office provides a fully featured, highly compatible, and completely free alternative for creating professional presentations without the hassle of missing customization options.

- 2. Open your existing presentation: Launch WPS Presentation and open your existing .pptx file seamlessly without losing formatting.
- 3. Edit your presentation effortlessly: Utilize the intuitive interface to customize your slides, fonts, and themes without dealing with missing menus or XML editing.
