Unfortunately I only have health insurance but not travel. I could've asked for an extra insurance for my rental car but being a poor student, I wanted to save money.
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.
