If you ordered direct from Apple yes. When your order goes to "shipped" you will see a place on your order online that allows you to pre-sign. Same goes if they shipped via UPS.
If you bough from another company then it depends on how they shipped -- indirect or direct signature. If it's indirect you can leave a note. If it's direct someone at the house must sign in person.
With FedEx you can also redirect to a FedEx Office location for pickup -- just sign up for
Delivery Manager. You can do this w/ UPS too before first delivery attempt but they charge for priveledge. You can arrange for p/u after the first delivery attempt for free. If you call the shipper before first attempt they can arrange for p/u at the UPS station at no extra charge if they are willing.
