Notes stored on your Mac
You can store notes on your Mac instead of in an online account (such as your iCloud account). If you store notes on your Mac, they arenβt available on any of your other devices.
Notes stored on your Mac appear below On My Mac in the sidebar. If you donβt see On My Mac in the sidebar, you can enable it.
Choose Notes > Settings, then select the βEnable the On My Mac accountβ tick box.
Note: If you later disable the On My Mac account, notes in your other accounts (such as iCloud) arenβt affected.
