Mac introduces a system in macOS Sonoma 14.1 that notifies Apple when liquid is detected in the USB-C port

Apple products such as the iPhone and Apple Watch are water resistant, but

AppleCare , a repair service for Apple products, does not cover damage caused by liquids . iPhones, iPods, and other devices have a liquid intrusion indicator in the device to check whether it has been damaged by liquid, but in the latest version of macOS Sonoma 14.1, if liquid is detected in the USB-C port, Apple will notify you. It has been revealed that a system for sending notifications has been added.

To determine if the damage to your iPhone is caused by liquid, the device has a built-in liquid intrusion indicator (LCI) that detects liquid intrusion. For iPhone 14 Pro, the LCI is located inside the SIM card slot.

According to a survey by Apple-related media 9to5Mac, macOS Sonoma 14.1, the latest version of the Mac OS at the time of writing, includes a new system

daemon named ``liquid detection''. ``liquiddetectiond'' is a feature that identifies when a Mac has been exposed to liquid, and it runs in the background and collects liquid detection analysis from each USB-C port on the Mac.

'liquiddetectiond' is also known as the 'liquid detection and corrosion mitigation daemon,' and iPhones and iPods also include a similar daemon. The iPhone version of the Liquid Detection Daemon alerts users if liquid is detected in the connector and notifies users to unplug the charging cable to prevent damage to the device.

However, analysis of the code of the Mac version of the liquid detection daemon suggests that this functionality is only used to analyze information and is not associated with end-user functionality. Apple may eventually implement an alert feature on Macs similar to the liquid detection daemon that already exists in iOS, but at the time of writing, 'The data collected will determine whether a Mac is covered by AppleCare. 9to5Mac points out.

Of course, this is just one way Apple knows if your Mac has been exposed to liquid. According to Apple's website , 'Current Mac notebook computers and some Apple wired and wireless keyboards are equipped with a liquid immersion indicator (LCI) to determine if the product has come into contact with liquid. ”, indicating that it is equipped with the same LCI as the iPhone.

It is unclear whether the Mac version of the liquid detection daemon will work on all Macs running the latest version of macOS, or whether it will only work on M3-equipped Macs due to additional hardware requirements.
