All Apple products, in our catalog, require you to select an option. This is required even if there is only one option to select (color, model, etc).
Therefore, you must click on to “select” all options (even if there is something written in the box by default).
For example, the first box “Case Material” has “Aluminum” showing by default. You must still click in this box to confirm the selections.
All options must be selected in order.
Once complete, you will be able to add the item to your cart and complete the check-out process.
