• The account that you entered when you first installed Mac OS X: If you entered the information for an email account, it’s available.

• Your .Mac account: If you registered for a .Mac service account, it will be included.

• Upgraded accounts: If you upgraded an existing Mac OS system, your existing Mail accounts will be added to the Accounts list in Mail.

Apple Internet Accounts App

Speaking of the Accounts list, choose Mail –> Preferences and click the Accounts button to display the Accounts dialog box that you see in Figure 1. From here, you can add an account, edit an existing account, or remove an account from Mail. Although most folks still have only one email account, you can use a passel of them. For example, you might use one account for your personal email and one account for your business communications. To switch accounts, just click the account that you want to use from this list to make it the active account.

Figure 1: The Accounts list, where all is made clear (about your email accounts).

To add a new account within Mail, click the Add Account button, which carries a plus sign, to open an Account wizard that leads you through the process.

You can also add an account from the Preferences dialog box. Open the Preferences dialog box by clicking Mail and choosing Preferences; then click the Accounts button on the Preferences toolbar. Follow these steps:

1. Click the Add button at the bottom-left corner of the window, which (also) carries a plus sign.

2. On the General Information panel, click the Account Type drop-down list box and choose the protocol type to use for the account.

You can select an Apple .Mac account, a Post Office Protocol (POP) account, a Microsoft Exchange account, or an Internet Message Access Protocol (IMAP) account. If you’re adding an account from an Internet service provider (ISP), refer to the set-up information that you received to determine which is right. Most ISP accounts are POP accounts.

3. In the Description field, name the account to identify it within Mail and then press Tab to move to the next field.

For example, Work or Mom’s ISP are good choices.

4. In the Full Name field, type your full name — or, if this is to be an anonymous account, enter whatever you like as your identity — and then press Tab.

Messages that you send appear with this name in the From field in the recipient’s email application.

5. In the User Name field, type the username supplied by your ISP for login to your email account and then press Tab.

This is sometimes different from the username and password that you use to connect to the Internet.

6. In the Password field, type the password supplied by your ISP for login to your email account.

Again, this password may be different from your connection password.

7. Click Continue.

8. Click Continue on the Account Summary sheet.

9. Click Done on the Conclusion sheet.

You’re done! The new account appears in the Accounts list.

Your Mac comes with specialized Apple apps: Safari web browser, Mail, Contacts, Calendar, Notes, Reminders, Messages, FaceTime, Photos & iMovie. You’ll want to use them whenever possible to get the full Mac experience. And if you’ve used an iPhone or iPad, they’ll immediately look familiar… but with even more features.

It’s easy to add email accounts, sync contacts and calendars, set up Facebook, Twitter, photo sharing, and instant message services on your Mac. It’s all done in one place: Internet Accounts in System Preferences.

1. Click System Preferences in the dock or select it from the Apple menu. Then click Internet Accounts.
2. To change settings on an existing account, select it in the list and skip to step 5.
3. To add an account, click + button under the list and choose your service on the right. To delete an account, select it and click the – button.
4. Enter the information requested, matching what you use to log into the service’s web page. Contact them for details.
5. Check the services you need. See more information below.
6. Click Details to change the description that shows on the left side. For example, if you have two Google accounts you might label one Personal and another Work.

Now you’re ready to learn how to use Mail, Contacts, Calendar and other apps.

Which checkboxes do you need to turn on? You don’t have to enable everything. For example, you might not enable Google contacts if you’re already syncing them through iCloud. But if you have a personal account and a company account, you might check the boxes next to Mail and Calendars in each account. The Mail app will then show both inboxes, and Calendar app both calendar systems. Even so, your home mail & calendars will be stored in your personal account, and your employer has no access to them on their system. That’s the beauty of the Apple apps: they can show information from multiple sources, while storing them separately and securely.

Having trouble? Your account and passwords on the Mac and the account’s web page must match. If you reset your account password on the web, you must change settings in Internet Accounts. Sometimes the easiest way to do this is to remove the account and add it again (step 3). Your data will be downloaded again.
