How Do I Make A Genius Bar Appointment?
Start out by visiting the Genius Bar site. Select your local Apple Store from the Genius Bar Reservations drop-down. You must then select the nature of your visit - Mac, iPad, etc. Finally, you will be presented with a list of available appointment times for the next several days. Select a date, fill in your contact info, and be sure to arrive early for your appointment. Upon arrival at the Apple Store, walk to the Genius Bar and check-in for your appointment.
A few tips before visiting: it is recommended that you update all the software on your device and also backup your device in case it needs to be erased for any reason. And remember, anyone can make a Genius Bar appointment. It doesn't matter if you didn't buy your Apple product from the Apple Store. It also doesn't matter if your warranty has ended or you didn't purchase an AppleCare Protection Plan.
