USB Type-C (often shortened to USB-C) is a general-purpose data transfer and power delivery connector, and is the means of wired data transfer on current iOS and Mac devices. Apple was significantly involved in developing the standard, and it is speculated that the connector design originated as a collaboration between Apple and Intel, before being provided to the USB Implementers Forum (USB-IF).[1]
Apple was an early adopter of USB Type-C, introducing it with the MacBook (Retina, 12-inch, Early 2015) as the only port on the device, other than the headphone jack. It was first introduced to the iPad with the iPad Pro (11-inch), and the iPad Pro (12.9-inch) (3rd generation), iPad Air (4th generation), and iPad (10th generation). It was introduced to the iPhone with the iPhone 15.
Implementations of USB Type-C on Macs, with the notable exception of all MacBook (Retina, 12-inch) models, support Thunderbolt 3 and either USB 3.1 or 3.2, with Apple Silicon models supporting Thunderbolt 4 and USB4. As of the iPad Pro (11-inch) (3rd generation) and iPad Pro (12.9-inch) (5th generation), iPad Pro models support USB4, a standard that is based on Thunderbolt 3.
