Apple’s One-Year Limited Warranty for MacBook Air excludes coverage for damage resulting from a number of events, including accident, liquid spill or submersion, unauthorized service and unauthorized modifications. If damage is outside the scope of warranty coverage, service may be available through a local AASP or an Apple retail store, but all service charges will be your responsibility. In such an event, you will be asked to approve the estimated charges and accept the terms and conditions for service before authorizing the repair. If the repair is performed at an Apple retail store Apple's Repair Terms and Conditions will govern service. Repair service for a MacBook Air that has experienced catastrophic damage, for example extensive liquid damage or a severe impact that results in the product being disassembled into multiple pieces, is generally not available and not eligible for service.
If the Messages app is not an option, Apple’s support site has detailed instructions for setting up the Mac for sharing in System Preferences and using alternative screen-sharing methods or iCloud’s Back to My Mac feature (until Back to My Mac is discontinued in the next version of the operating system). If you are remotely trying to configure settings on someone else’s Mac and you both have iOS devices, Apple’s FaceTime video chat app can be helpful for visual cues walking someone through setup steps; Microsoft Skype users can also share screens for visual reference.
To the Apple rep here. Worked in IT and hated my monthly rotation when I tested as a cust. supp. level 2 rep. It is stressful and I agree - be prepared to wait or have Apple call back. When I was looking for a job, I considered cust. supp. for a brief time and warned my spouse I'd be stressed out if I took the job, so again, I understand. But I'm a user and this is different.
Much like Apple handles support calls over the phone, soon only customers within their warranty period will be able to access online chat support through getsupport.apple.com for free. For others, Apple will charge what it refers to as a “pay per incident” fee or require the purchase of an extended warranty through AppleCare. Previously all online support chat features were available for free to users worldwide. Some users might have noticed back in August when Apple revamped its support sites that it started listing a $19.99 per incident fee for chat support. However, up until now AppleCare hasn’t actually been charging users to access the feature.
