Macs can now inform Apple if any liquids have been detected in the USB-C ports
Apple’s limited warranty doesn’t cover damage caused by liquids, even for water-resistant products like the iPhone, Apple Watch, and some AirPods models. Because of this, Apple has different methods to detect if the device has been exposed to liquids. And on the latest Macs, Apple now has a way of knowing if liquids have been detected in the USB-C ports.
