Thank you for visiting Apple Support Communities.
I see you are using an iMac and assume that it is running Mavericks. With Mavericks the only way to sync information via the Info tab would be to use iCloud. Here is some information that will walk you through the process of using iCloud.
If you use OS X Mavericks v.10.9 or later, your contacts, calendars, and other info are updated on your computers and iOS devices via iCloud. For more information, see iCloud Help at icloud.com.
If you are running Mountain Lion or earlier, see the steps in the article below.
