Apple Macs get digital liquid detection feature for USB-C ports
Apple uses various methods to determine liquid exposure in its devices, as liquid damage isn't covered under warranty. Mac laptops and some Apple keyboards have liquid contact indicators (LCI) inside, which change color when exposed to liquids. And now, with the macOS Sonoma 14.1, Macs also feature a new system daemon, "liquiddetectiond," that detects liquids in USB-C ports, reported 9to5Mac. iPhones and iPads already have a similar feature, but the Mac version is currently used only for analytics.
