description: "The M series did not appear out of thin air; its prototype can be traced back to the A12Z. Before the release of the M1, Apple had launched a Mac mini (DTK) equipped with the A12Z running macOS. The A12Z itself was a modified version based on the A12.Similarly, the S series in watches are also variants of the A series' low-power cores (for example, the S7 adopted the performance cores of the A15).The essence of Apple integrating its underlying architecture is to bridge the gap in cross-platform development and ensure a high degree of synchronization in the software ecosystem. However, it's basically impossible for a single device to run different operating systems.Craig has repeatedly denied in interviews the idea of forcibly merging macOS and iPadOS. From a business strategy perspective, integrating multiple systems would cause severe internal friction within the product line, affecting the differentiated sales of iPads and Macs, which completely contradicts Apple's commercial interests."
