Question details
The user is looking for a way to compare differences between two PowerPoint presentation files on a Mac.
- Product
- Microsoft PowerPoint for Mac
- Device & OS
- macOS
- Scenario
- Reviewing changes, edits, or discrepancies between two versions of the same presentation.
- Observed behavior
- The built-in 'Compare' feature that exists in PowerPoint for Windows is missing in the macOS version of the software.
Before using any web-based comparison tools, ensure your PowerPoint files do not contain sensitive or confidential business data, as uploading them may expose you to privacy risks.
Compare PowerPoint Files Manually Side-by-Side
Since PowerPoint for Mac lacks a native comparison tool, arranging the two presentation windows side-by-side is the safest way to visually inspect differences without uploading your files online.
macOS offers a built-in Split View feature that makes it easy to arrange two windows perfectly side-by-side. This method guarantees that your confidential data remains secure on your local drive.
Launch PowerPoint for Mac and open both the original and the modified presentation files.
Hover your cursor over the green full-screen button in the top-left corner of one presentation window. Choose 'Tile Window to Left of Screen' from the dropdown menu.
Click on the second PowerPoint presentation window on the right side of the screen to fill the remaining space.
Scroll through the slides manually in both windows to identify layout changes, text edits, or modified graphics.
Use a Third-Party Online Comparison Tool
If your presentations do not contain sensitive information, you can use free web-based services like Aspose to automatically detect differences between two files.
Submit a Feature Request to Microsoft
Since native comparison support is currently exclusive to Windows, submitting direct feedback can encourage Microsoft to add this functionality to macOS.
