Display Model Switches
So user-owned Apple products are nearly impossible to break into. But what about the display devices at brick-and-mortar Apple retail locations? It turns out that those devices may actually be a worse target for most thieves.
That’s because all Apple display products have a special OS image installed onto them. That image automatically activates a “kill switch” which renders a device useless when it leaves the premises of a store. All a stolen device can do is send a location back to the store until it dies. And at that point, it’s a brick.
