Frequently Asked Questions

Will changing the default font affect my existing Word and Excel files?

No, changing the default font settings in Word or Excel only applies to new, blank documents and workbooks created after the change. Your previously saved files will retain their original font and formatting settings.

Why did my font revert back to the old default after I restarted Word for Mac?

This usually happens if the Normal.dotm template fails to save properly. Make sure that when you quit Word, you click 'Save' if a prompt asks to save changes to the Normal global template. Additionally, verify that you selected 'All documents based on the Normal template' when initially setting the default font.

How do I find and backup the Normal.dotm template on my Mac?

The Normal.dotm template is typically located in the hidden Library folder. You can access it by opening Finder, holding down the 'Option' key, clicking 'Go' in the top menu, selecting 'Library', and then navigating to Group Containers > UBF8T346G9.Office > User Content > Templates. You can copy this file to backup your custom default fonts and macros.
