OP,
Did you ask the apartment complex to take possession of the package in your absence? If not, is there anything in your lease agreement that states they will do so for any and all mail too large for mail slot, and or packages that require a signature? If you did not ask them to take temporary possession (otherwise known as a Bailment Agreement under the law) by verbal consent or signed lease agreement, you can still have standing for remedy.
If the answer to the aforementioned is yes, the onus will be upon you to prove the packages were empty before possession was received via a signature, which you won't be able to do.
Unless Apple shows compassion to you, I don't see you winning this. The only way I see you winning this is if the chain of custody and protocol was violated by a member(s) of UPS.
In the future, do not enter into any "Bailment Agreement." Make arrangements to take personal possession upon delivery.
