Stop USB–C port rot
WHETHER IT’S IN perfecting the roundness of corners or simplifying the task of unboxing, you’ve got to love Apple’s attention to detail.
If you have an Apple silicon MacBook, you may have come across another example in Accessory Security. Because there are folk going around who’d like to connect their malicious peripheral to your Mac, Apple gives us a way to lock them out.
But in some more recent M3 and M4 notebooks, Apple has another surprise inside each USB–C port: a liquid sensor. When those were discovered, they were mistaken for the detectors that are now commonplace inside most notebooks, which reveal whether damage has resulted from ingress of liquid. These new in–port sensors can warn you if the inside of the port is wet, and let you dry your Mac out before it becomes damaged.
