Always Make an Appointment
Sometimes, your phone or computer will have an issue that prevents complete functionality. But, if your issue is an inconvenience and isn’t a total “show stopper,” try to make a Genius Bar appointment in advance for a day that works best for you.
When heading to an Apple Store right away, remember that other people have been waiting to see a technician anywhere from an hour, all the way up to two weeks. Any “walk-in” appointment can take a few hours or more to be seen that same day. Also, you will need one appointment for each device to be repaired.
