Apple is testing a new Web chat support service for iMac owners. The service is available 24 hours a day, 7 days a week. To begin a chat session with an Apple representative, users must enter their name and iMac serial number. “It’s fast, it’s easy, it’s convenient, and you’ll get proactive, comprehensive help from a real live person right here in your browser. If you can’t find what you’re looking for on Apple’s iMac Support pages, give chat support a try. A support agent can even send you helpful web pages while you’re chatting.”
