In this video, I go over the process of upgrading Apple Silicon Macs, specifically an M1 MacBook Air in this case, to the maximum of 2TB of storage. This guide covers performing the upgrade on any machine with a standard M1 or M2 CPU (supports 2 NANDs only) that utilizes BGA110 NAND chipsets. In this instance, I successfully upgraded an odd education model M1 MacBook Air, from a single-NAND 128GB configuration, all the way to a dual-NAND configuration total of 2TB.
