Use reminders from your Internet accounts on Mac
If you keep your reminders in Internet accounts — for example, iCloud, Exchange, Yahoo or AOL — you can use the accounts in Reminders on your Mac, and access all your reminders in one place. Set up your iOS devices to use the same account, so that your reminders stay up to date across all your devices.
If you use only one account with the Reminders app on Mac, the title of the account in the sidebar is “My Lists”. If you use multiple accounts, the title of each account is the provider name (for example, iCloud or Yahoo) or the the description in the account details.
Note: All Reminders features described in this guide are available when using upgraded iCloud reminders. Some features aren’t available when using accounts from other providers.

You can view, add and modify reminders in the Reminders app on all your devices that use the same accounts. You can also view, add and modify your iCloud reminders on iCloud.com. Changes you make show up everywhere, so you always have your most current reminders at hand. Reminder notifications also appear on your Mac and other devices that use the same accounts.
