FWIW, liquid (pin-shortage) detection on the USB-port is a standard feature of all Smartphones with IPxx water-ingress certification.
It prevents the device from applying/draining power from any pin in such a state, mainly to reduce corrosion of the contacts and increase longevity.
(Without such a mechanism, an IPxx device may be unable to charge within a few weeks as the contacts of the connector can deteriorate quite fast)
As to why Apple ported the daemon from iOS to macOS....well, for sure a good indicator to reduce warranty repair-costs...
- DannyBee 3y agoYes, it is, and most of them get it from the same chipsets :) They are not making their own, it's a function of the controller of the USB-C PD port they use.
- dharma1 3y agoOn iOS you can thankfully override it (the alert dialog lets you do it) in case of an emergency - which is pretty handy if you’ve had the phone in the pool/shower and really need to charge it and don’t have a blow dryer to hand. Less frequent of an issue for laptops I would hope :D
- rickdeckard 3y agoNow that override is something I would log as a vendor, because THAT's when the corrosion happens on the connector...
