Fix PowerPoint for Mac Using the Wrong Spelling Language
Question details
The user needs to resolve an issue where PowerPoint for Mac applies the wrong language for spell check and autocorrect despite the correct default being set.
- Product
- PowerPoint for Mac
- Device & OS
- Mac
- Scenario
- Editing an existing presentation where the default proofing language is ignored during spell check.
- Observed behavior
- PowerPoint continues to use a foreign language dictionary (such as German) for spelling and autocorrect on existing text, completely bypassing the default American English setting in Microsoft 365.
Ensure you have saved your presentation progress and verify that the correct language dictionary is installed on your Mac system settings.
Change the Proofing Language for Existing Text and Placeholders
Apply the correct language directly to all existing text elements, as PowerPoint's default settings only affect newly created presentations and text boxes.
In PowerPoint for Mac, the default language setting only applies to new presentations and newly created text boxes. Any existing text retains the language formatting it was originally typed or pasted with. To fix the spell checker, you must manually select the existing text and reapply your preferred proofing language.
Open your presentation, go to the 'View' tab in the top ribbon, and click on 'Outline View'.
Click anywhere inside the outline pane on the left side of the screen and press 'Command + A' on your keyboard to select all the text.
Navigate to 'Tools' in the top Mac menu bar and select 'Language' from the dropdown menu.
Select 'English (US)' or your desired language from the list and click 'OK'. This will update the spelling language for all standard placeholders.

Frequently Asked Questions
Why does my PowerPoint keep reverting to another language?
PowerPoint assigns language attributes on a character-by-character basis. If text was originally pasted from a document in a different language, or if your keyboard input source was temporarily switched while typing, PowerPoint embeds that specific language into the text block, ignoring the application's global default.
How do I change the default proofing language for all future presentations?
To change the default language for new files on a Mac, open a blank PowerPoint presentation, go to 'Tools' > 'Language' in the top menu, select your desired language, and click the 'Default' button. Confirm the prompt to apply this to all future files based on the Normal template.
Can I apply the language change to all slides at once without Outline view?
Unfortunately, PowerPoint for Mac does not have a single 'apply to all' button for proofing languages that affects manually inserted shapes and text boxes. You must use the Outline view to mass-update standard placeholders, and manually update any custom shapes.
