Add clickable links automatically to documents in TextEdit on Mac
When you use smart links, any web addresses you enter in new TextEdit documents become clickable links. For example, “www.apple.com” turns into a link that opens the website. And “mailto:firstname.lastname@example.org” turns into a link that creates an email for Karina Cavanna.
In the TextEdit app on your Mac, choose TextEdit > Preferences, then click New Document.
Select “Smart links” under Options.
For information about clickable links, see Add links to documents.
