If you bought the macbook on a credit card, that will occasionally include insurance for theft, loss or damage. I knocked my new iPad off my desk a week after buying it and visa paid for a replacement with very little hassle.

There's also a chance that the credit card you used to purchase the items had a purchase protection clause, though they're often time-limited and some don't cover theft from a car.

Renter's insurance can also cover lost items like that. Don't suppose you have that, do you?
