macOS Sonoma's Mysterious Liquid Detection: Debunking the Myth
2025-03-23
This article investigates a new background process, `liquiddetectiond`, that appeared in macOS Sonoma 14.1. Initially, it was wrongly suspected as an Apple tool to collect user data for warranty denials. However, investigation reveals it actually detects liquids in USB-C ports to prevent corrosion and prolong device life, not for data collection or warranty avoidance. The functionality is only available on select new MacBook and MacBook Pro models, and logs show it operates locally without sending data to Apple.
