Add or remove accounts in Notes on Mac
If you keep notes in Internet accounts—for example, iCloud, Google, Yahoo, or AOL—you can add those accounts to Notes on your Mac.
Note: You don’t need an Internet account to use Notes. You can store notes only on your Mac, but these notes won’t appear on your other devices.
