If you're new to the Mac but something of an iOS veteran, this lesson will be a snap. And it should be, because Apple modeled Mountain Lion's Mail, Contacts & Calendars system preference on the setting of the same name found on today's iPhone, iPod touch, and iPad.
If anything, the Mountain Lion version is actually easier to use because it isn't crammed with additional settings specific to the Contacts, Calendar, and Reminders applications. Much as I love discussing the ins and outs of contacts, events, and reminders, our focus here will be on setting up email accounts on your Mac.
Adding a service
Launch System Preferences and, in the Internet & Wireless area, click Mail, Contacts & Calendars. If you took advantage of the offer to set up an iCloud account when you first configured your Mac, you'll see an iCloud entry in the list of accounts on the left side of the resulting window. To the right of that list is a series of commonly used services, including (in the United States) iCloud, Microsoft Exchange, Gmail, Twitter, Facebook, Yahoo, AOL, Vimeo, and Flickr. At the very bottom of the list is an Add Other Account... entry.
To use these services, you must first set up an account with them--something that you can't do within this preference. If, for example, you wish to set up a Gmail account, launch a Web browser (Apple's Safari is the default) and travel to http://www.gmail.com. Create your Gmail account here, making a note of your username and password.
Now that you have an account, let's set it up. Click the Gmail item in the Mail, Contacts & Calendars list. A sheet pops down with Name, Email Address, and Password fields. In all likelihood the Name field will be filled in already; if it isn't, do so. Then, just enter your Gmail address (in the form firstname.lastname@example.org), enter your password, and click Set Up.
As long as your Mac is connected to the Internet, it will create the correct settings so that you can use Gmail's mail, calendars, reminders, messages, and notes features. You'll know that its efforts have been successful if a sheet appears that lets you choose which of Gmail's features to use. If you don't wish to use all of the features--for example, you'd rather not sync your Gmail calendars and reminders with your Mac's Calendar and Reminders applications (and I'll talk about why you might not want to do this when I discuss those specific applications in a later column)--simply uncheck the ones you'd prefer to do without.
When you're done, click Add Account. You'll see a spinning gear icon next to the enabled features, which indicates that your Mac is syncing Gmail's data with the appropriate applications on your computer. You will notice as well that your Gmail account now appears in the list of configured accounts. If you'd like to use a different name for your account, select it, click the Details button to the right, and in the sheet that appears, enter a new name in the Description field and click OK.
