AppleCare+ for iMac

Most Apple hardware comes with a one-year limited warranty and up to 90 days of complimentary telephone technical support. To extend your coverage further, purchase the AppleCare Protection Plan or AppleCare+.
Because Apple makes the hardware, the operating system, and many applications, Apple products are truly integrated systems. And only AppleCare products give you one-stop service and support from Apple experts, so most issues can be resolved in a single call.
