Dear Tony,
Thank you for reaching out to the Microsoft Q&A Community.
I understand you're facing an unexpected issue with click-and-drag highlighting only in Word for Mac. Since it works everywhere else, the problem is almost certainly specific to your Word desktop application.
Here are the key steps to resolve this:
1.Test Word in Safe Mode:
- Quit Word completely.
- Hold down the Option key while clicking the Word icon to open in Safe Mode.
- Test highlighting. This helps identify if add-ins or a corrupted template are the cause.
- If it works in Safe Mode: Proceed to step 3 (Disable Add-ins).
- If it still doesn't work: Proceed to step 2 (Reset Word Preferences).
2.Reset Word Preferences:
- Quit Word and all Office apps.
- Go to Finder > Go > Go to Folder...
- Type ~/Library/Containers/ and drag the Microsoft Word folder to your Desktop (backup).
- Again, Finder > Go > Go to Folder...
- Type ~/Library/Group Containers/UBF8T346G9.Office/ and drag the User Content.localized/Startup/Word/Normal.dotm file to your Desktop (backup).
- Restart Word and test.
3.Disable All Add-ins (If Safe Mode worked):
- Open Word normally.
- Go to Tools > Word Add-ins.
- Uncheck all add-ins, restart Word, and test. Re-enable them one by one to find the culprit.
