i want to make a reservation at Kahala for my computer

You can contact the Kahala Apple Store to set a reservation for an appointment

with a Genius by using this link:

• Kahala - Apple Store - Apple (Hawaii)

http://www.apple.com/retail/kahala/

By clicking the "Genius" tile in main page it opens; to where you can choose

the product selector and set up the rest of the details for the reservation there:

https://getsupport.apple.com/

Or in general, use this goes to the same place as the one immediately above.

http://www.apple.com/retail/geniusbar/

There are a few choices, but it is best to have the appointment set ahead of arrival

and the quality of your experience improves greatly with the reservation in advance.

(I know of some who just arrive at the store and didn't have an appointment, to wait.)

Good luck! 🙂
