Because previous owner left "Find Me" on and Amazon does not take care of this, it took 7 months to be able to send the machine into tech support at Apple to get it fixed. And many hours on the phone with Apple. And myriad hours putting together "Proof" I purchased item (they wanted receipt with serial number). Great machine. Not happy to get one with a dead camera and with Find Me turned on. A headache that made it a bad purchase.
