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.

Each account you add is listed separately in the sidebar. If the sidebar isn’t showing, click the Sidebar button

Be sure to set up your iOS devices to use the same notes accounts, so that your notes stay up to date across all your devices.
