Shortly after an image surfaced apparently showing a notch on the M1X MacBook Pro models, it did not take long for another rumor to circulate, stating that the 2022 MacBook Air would sport the same notch. The successor to the M1 MacBook Air is said to arrive with a design change, and perhaps the most significant cosmetic changes could be the one described.

A tipster who goes by the name ‘ty98’ on v2ex claims the 2022 MacBook Air’s design change. Unfortunately, the fresh information does not provide a reason as to why Apple would choose this route, but we feel that it would have to do with more than just adding a regular aesthetic change. For instance, the iPhone X that launched in 2017 featured that notch to accommodate the TrueDepth camera and other components necessary to equip the handset with Face ID capabilities.
