iCloud notes

You can store notes in iCloud so that you can view and edit them on all your devices and on iCloud.com. Notes stored in iCloud appear below iCloud in the sidebar of the Notes app. If you don’t see iCloud in the sidebar, you need to sign in to iCloud and turn on the Notes feature in iCloud settings.

To turn on iCloud notes, choose Apple menu > System Settings, then click [your name] in the sidebar. Click iCloud on the right.
