With the M2 MacBook Air, Apple replaced an Intel-made component responsible for controlling the USB and Thunderbolt ports with a custom-built controller, meaning the last remnants of Intel are now entirely out of the latest Mac .


Earlier this month, repair website iFixit shared a teardown of the new “MacBook Air” and gave a glimpse of the completely redesigned device. A subtle detail that went largely unnoticed was that the latest “MacBook Air” introduces custom controllers for the USB and Thunderbolt ports, unlike previous Macs.

iFixit mentioned it in its report, stating that they found an “apparently Apple-made Thunderbolt 3 driver instead of the Intel chips we’re aware of.” The new component was shared on Twitter todaywhere it got more attention.

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