Fix PowerPoint Master Slide Names Not Appearing Correctly on Mac
Question details
Users are unable to see custom names for slide masters and layouts in the Layout menu after renaming them in Slide Master view.

- Product
- Microsoft PowerPoint
- Device & OS
- Mac and Web
- Scenario
- Renaming slide layouts in Slide Master view to create custom presentation templates.
- Observed behavior
- The assigned custom names do not display in the Layout dropdown menu outside of the Slide Master view; default or incorrect layout names appear instead.
Because this workaround involves modifying internal presentation XML files, ensure you create a backup copy of your original .pptx file before proceeding.
Edit the Presentation XML Files Manually
Modifying the internal XML code of your PowerPoint file ensures the display name accurately matches your custom layout name.
This issue occurs because PowerPoint sometimes updates the 'name' attribute in its underlying XML structure but leaves the 'matchingName' attribute unchanged. Editing the archive directly bypasses this software bug.
Create a copy of your .pptx file and change its file extension from .pptx to .zip so it can be extracted.
Use a standard archive utility on your Mac to unzip the renamed file into a new folder.
Navigate through the extracted folder to the path 'ppt/slideLayouts'. Here you will find XML files for each layout, such as slideLayout1.xml.
Open the affected XML files with a text editor. Locate the 'name' and 'matchingName' attributes inside the code, and edit the 'matchingName' value so it exactly matches the 'name' value.
Save your changes to the XML files, compress the entire folder structure back into a .zip archive, and rename the extension back to .pptx.

Create and Manage Slide Masters Easily with WPS Presentation
Avoid complex XML editing and software bugs. WPS Presentation provides a seamless, stable environment for designing custom slide masters and layouts. It's fully compatible with Microsoft PowerPoint formats, easy to use, and completely free.
- 1. Open your presentation: Download and install WPS Office, launch WPS Presentation, and open your .pptx file.

- 3. Rename your layout: Right-click the specific slide layout thumbnail on the left pane, select 'Rename Slide Master', and enter your desired custom name.
- 4. Apply and exit: Click 'Close Master View'. Your custom layout names will now reliably appear in the standard Layout dropdown menu.

Frequently Asked Questions
Why do my renamed PowerPoint layouts revert to default names?
This is typically caused by a known software glitch where PowerPoint updates the layout's 'name' attribute in its underlying XML code but fails to update the 'matchingName' attribute, causing the interface to display the old or default name.
Does this slide master naming bug affect all versions of PowerPoint?
Users have reported this specific issue primarily on PowerPoint for Mac (including version 16.89.1) and PowerPoint for the Web. The issue often persists when these files are shared.
Can I rename slide layouts without editing XML files?
If the standard rename function in Slide Master view fails to update the display name in the Layout menu, manually editing the XML file or using stable alternative presentation software like WPS Office are currently the most effective workarounds.
