Add an internet account
You can add an internet account or other type of account. Some accounts can be used with multiple apps.
Click the Add button , then select an account provider.
If you don’t yet have an account from a particular provider, such as Yahoo, create one on the provider’s website, then add it here.
To add an account from a provider that isn’t listed, such as a mail or calendar account for your company or school, do either of the following:
From an app: Click Add Other [Type of] Account, then click Continue.
From Internet Accounts preferences: Click Add Other Account, then select the type of account to add.
Enter the requested account information.
If you don’t know the account settings, ask the account provider.
If you’re adding an account that multiple apps can use, a dialog appears in which you select the apps you want to use with the account.
The account you add appears in Internet Accounts preferences, where you can remove the account or change its settings. See Use your internet accounts on Mac.
