Fix Word for Mac AutoCorrect Not Fixing Spelling Errors
Question details
The user needs to know why AutoCorrect is not automatically fixing specific spelling mistakes on macOS Sequoia, despite underlining them.
- Product
- Microsoft Word for Mac
- Device & OS
- macOS Sequoia
- Scenario
- Typing text where automatic replacement of specific misspelled words is expected.
- Observed behavior
- Misspelled words are underlined but not automatically corrected by the AutoCorrect feature.
Ensure that the correct proofing language is applied to your entire document, as AutoCorrect functions depend on the currently selected language.
Update AutoCorrect Preferences with Missing Entries
Since AutoCorrect only replaces entries that are explicitly included in its dictionary, you can manually add your recurring typos to the AutoCorrect list.
Word does not automatically correct every misspelling. Instead, it relies on a predefined list of common typos and their replacements. If your specific typo is not on this list, it will only be underlined.
Launch Microsoft Word, click on 'Word' in the top macOS menu bar, and select 'Preferences'.
In the Preferences window, locate and click on 'AutoCorrect'.
In the 'Replace text as you type' section, enter your frequently misspelled word in the 'Replace' box and the correct spelling in the 'With' box, then click 'Add'.
Temporarily Revert Office for Mac Version
If the AutoCorrect issue started after a recent update to macOS Sequoia and adding custom entries does not work, reverting to a stable older version of Office (like 16.93) may restore functionality.
Experience Seamless Typing with WPS Office for Mac
If Microsoft Word for Mac continues to struggle with AutoCorrect and performance issues on macOS Sequoia, consider switching to WPS Office. It provides a lightweight, highly compatible alternative with robust spell check and typing assist features.
