If text formatting disappears in TextEdit on Mac
If you suddenly lose all formatting in a document, you may have accidentally converted your file’s format from rich text to plain text.
In the TextEdit app on your Mac, try any of the following:
Revert to a previous version of your document.
Choose Edit > Undo one or more times.
Choose Format > Make Rich Text, then reformat the document.
