In the M2 MacBook Air, Apple replaced an Intel-made component responsible for controlling USB and Thunderbolt ports with a dedicated controller, meaning the last leftovers from Intel are now out of the latest Macs.


Earlier this month, repair site iFixit shared the teardown of the new MacBook Air, revealing a look inside the completely redesigned device. One subtle detail that’s largely gone unnoticed is that unlike previous Macs, the latest “MacBook Air” offers dedicated controllers for USB and Thunderbolt ports.

iFixit mentioned this in their report, noting that it specified an “apparently Apple-made Thunderbolt 3 drive, rather than the Intel chips we’re familiar with.” The new ingredient was Shared on Twitter earlier todayWhere it got more attention.

Few details are known about the controllers, including whether they are custom made by Apple or a third party. In May 2021, Bloomberg Mark Gorman reports that Apple plans to “replace the last part of Intel with an internal version. Apple’s current M1 Macs still use an Intel component known as USB Retimer, which helps power the USB-C and Thunderbolt ports on their computer.”
